Convert a whole Outlook PST mailbox to PDF, attachments and all

A .pst file is a sealed box. It holds years of email, often with the important material buried in attachments, and it only opens cleanly in Microsoft Outlook. The moment someone outside that world needs the data, the problems start. A lawyer asks for a custodian’s mailbox for review. Compliance needs a five-year retention copy in a format auditors can actually read. An employee leaves and IT has to archive their inbox before the license is reclaimed. In every one of these cases, “here is a PST file” is not a useful answer.

The standard workaround is painful. You open Outlook, print each message to PDF one at a time, then chase down every attachment by hand and save it next to the email so nothing gets lost. For a mailbox with a few thousand messages, that is days of work, and it is exactly the kind of manual process where attachments quietly go missing.

reaConverter 8 now converts PST to PDF directly, with no Outlook required. More importantly, it does something most PST converters cannot: it keeps the original attachments as real, openable files embedded inside the PDF. Convert a mailbox with hundreds of emails into a single PDF, open it in Acrobat Reader, and the Attachments panel appears on the side. Every original file is right there to open or save.

Short answer: Install reaConverter 8, add your .pst files, choose PDF as the output format, enable the option to embed attachments, and click Convert. reaConverter reads the PST without Outlook, writes the email text into the PDF, and stores each attachment as an embedded file you can open from the PDF’s Attachments panel. It runs as a batch, so an entire mailbox becomes one searchable document in a single pass.

Why convert PST to PDF?

PST (Personal Storage Table) is Microsoft Outlook’s local data format. It stores messages, folders, and attachments in one proprietary container. That design is fine while you live inside Outlook, and a real obstacle the moment you need to share, archive, or review that mail anywhere else.

PDF solves the parts PST gets in the way of:

• Universal access. Anyone can open a PDF, on any device, with no Outlook license and no special viewer.
• Long-term archival. PDF, and PDF/A in particular, is a recognized preservation format. PST is tied to a specific application and its versions.
• Search and review. The email text becomes selectable, searchable text inside the document.
• A fixed, shareable record. A PDF looks the same to everyone who opens it, which matters when the document is evidence or a formal record.

Common situations where teams need PST to PDF:

• E-discovery and litigation. Counsel needs custodian mailboxes in a reviewable, productionable format, with attachments intact.
• Compliance and retention. Regulators and internal policy require email kept in a stable, readable format for a set number of years.
• Offboarding and mailbox archiving. A departing employee’s inbox has to be preserved before the account is decommissioned.
• Email migration. Moving off Exchange or consolidating accounts, where legacy mail needs a portable archive.
• Public records and FOIA responses. Email has to be handed to people who do not run Outlook.
• Personal backup. Keeping a clean, openable copy of your own mail outside the application that created it.

The recurring failure point in all of these is the attachment. A contract PDF, a signed agreement, a spreadsheet of numbers: that is often the actual evidence, not the email body. Many PST converters either drop attachments, flatten them into flat images you can no longer use, or scatter them into a separate folder that loses its link to the message. reaConverter keeps each attachment as the original file, embedded in the same PDF as the email it arrived with.

PST vs PDF, quick reference

What makes reaConverter’s PST to PDF different

Two things set this conversion apart from the usual “print each email” approach.

Many emails become one PDF. Point reaConverter at a PST and it can walk every message and write the whole mailbox into a single, paginated PDF. The email text goes in as real text, so the document is searchable end to end.

Attachments stay as files, not pictures. This is the part that matters for legal and compliance work. Instead of rasterizing a spreadsheet into a screenshot, reaConverter embeds the original file inside the PDF. Open the result in Adobe Acrobat Reader and the Attachments panel (the paperclip icon) opens automatically. Each attachment can be opened in its native application or saved back out, exactly as it was sent. You get one self-contained document that still carries the original evidence inside it, which keeps your record intact rather than degraded.

Why not just use Outlook’s Print to PDF?

If you only need to save one or two emails, Outlook’s built-in Microsoft Print to PDF does the job. The trouble starts past that. Outlook prints the message body and nothing else, so attachments are dropped. There is no batch option, so a mailbox of a few thousand messages means a few thousand manual prints. And it only works while Outlook is installed and the mailbox is loaded, which rules out reading an archived .pst on a machine that has no Outlook on it at all.

reaConverter approaches the same task from the file rather than the application. It opens the .pst directly, converts the whole mailbox in one pass, and keeps every attachment as an openable file inside the PDF.

For a handful of messages, Outlook is enough. For a mailbox you need to archive, hand to a lawyer, or keep for compliance, reaConverter turns a multi-day manual task into a single batch job.

What you’ll need

• reaConverter 8. The Standard edition is enough for GUI batch conversion. Watch Folders and command-line automation require Pro. See the PST to PDF conversion page for an overview of what is supported.
• Your .pst files. reaConverter reads PST directly, both the older ANSI and the modern Unicode variants.
• No Microsoft Outlook, Exchange, or internet connection. Conversion runs entirely offline on your own hardware, which is what you want when the mail is sensitive.

Method 1 — Convert PST to PDF in the GUI

This is the fastest way to convert one or several PST files interactively.

Step 1. Add your PST files

Launch reaConverter and load your mailboxes. You can:

• Drag and drop .pst files or whole folders from Windows Explorer.
• Use the Add Files or Add Folder buttons on the toolbar.
• Right-click a PST file in Explorer and choose Convert from the context menu.

reaConverter opens the PST and reads its messages directly. No Outlook process is launched at any point.

Step 2. Choose PDF as the output format

In the bottom panel, set Save as → PDF. You do not need to configure anything for the attachments: reaConverter embeds each email’s original attachments into the PDF automatically. That default behavior is what populates the Attachments panel when you open the file in Acrobat.

The gear icon next to PDF opens the PDF format settings. There are no email-specific options here, but a couple are worth knowing for an email archive. Create PDF/A document produces a preservation-grade file for long-term or compliance storage, and the Document Open password and permissions options let you lock down a mailbox that holds sensitive material.

To combine an entire PST into one continuous PDF instead of a separate file per message, open Saving settings (the gear on the far right, next to Convert) and go to the Multipage files tab. By default reaConverter keeps each item separate (“Convert each multipage file to another”). Switch to Save all processed files to one file to merge the whole mailbox into a single document.

Step 3. Set the destination folder

Choose where the converted PDF should be saved. You can keep the source folder structure, save everything to one flat folder, or use reaConverter’s subfolder naming options.

Step 4. Click Convert

Hit Convert and reaConverter processes the mailbox. The conversion log shows progress message by message. When it finishes, click Show converted files to jump straight to the output folder.

Step 5. Open the result and check the attachments

Open the PDF in Adobe Acrobat Reader. The email text is laid out as searchable text, and the Attachments panel opens on the left. Click the paperclip icon if it is collapsed. From there you can open any original attachment or save it back to disk.

Other formats you can convert PST to

PST to PDF is the headline, but the same engine handles the rest of reaConverter’s catalog. Once a PST is loaded, you can convert its content to other formats too, for example rendering messages to JPG, PNG, or TIFF when you need image output instead of a document. All of it runs as a batch, so whole folders of mailboxes go through in one pass.

Method 2 — Watch Folders (fully automated)

Watch Folders turn any Windows directory into a self-converting hot folder. Drop a PST in, and a PDF appears in the output directory with no clicks. This suits recurring archival jobs: an offboarding folder where IT drops departed-employee exports, or a compliance inbox that needs a PDF copy of every PST that lands in it.

How to set it up

1. Open reaConverter and go to Menu → Watch Folders → Add new folder…
2. Set the Source folder, the directory reaConverter will monitor, for example C:\Mail\PST_inbox\.
3. Set the Output folder, for example C:\Mail\PDF_archive\.
4. Choose PDF as the output format and enable embed attachments and merge-to-single-PDF as in Method 1.
5. Click Start Watching.

From then on, every PST that lands in the source folder is converted automatically and the PDF is written to the output folder. reaConverter keeps running in the background and can watch several folder pairs at once.

Tip: Combine the “Subfolder of source folder” output option with “Read subfolders” to mirror your directory structure while keeping originals separate from the converted PDFs.

For a full walkthrough, see the dedicated guide: A Beginner-Friendly Guide to reaConverter’s Watch Folders.

Method 3 — Command-line conversion

reaConverter Pro includes cons_rcp.exe, a full command-line tool that accepts the same settings as the GUI. It can be driven from batch scripts, PowerShell, Task Scheduler, or any automated pipeline.

Convert a single PST to one PDF with attachments

cons_rcp.exe -s "C:\Mail\custodian.pst" -o "C:\Output\custodian.pdf"

Batch convert a folder of PST files

cons_rcp.exe -source_folder "C:\Mail\" -source_ext pst -dest_path "C:\Output\" -dest_ext pdf

This converts every .pst file in the source folder, merges each mailbox into its own PDF, and embeds the attachments.

Include subfolders and run silently

cons_rcp.exe -source_folder "C:\Mail\" -source_ext pst -dest_path "C:\Output\" -dest_ext pdf -read_subfolders 1 /hide

Add /hide to suppress the console window for scheduled tasks, and append > "C:\Logs\pst_to_pdf.txt" to capture the conversion log. Saved as a .bat file and pointed at Task Scheduler, this becomes a nightly, hands-off PST archival job.

Troubleshooting

I don’t see the attachments in the PDF. Make sure you opened the file in a reader that supports embedded files, such as Adobe Acrobat Reader, and that the Attachments panel (the paperclip icon) is expanded. Some lightweight or in-browser PDF viewers do not display embedded files even when they are present. The data is in the PDF either way, so reopening it in Acrobat will show it.

The PST is very large. Mailboxes that run to many gigabytes take longer and use more memory. Convert during off-hours, or split the work across folders and let Watch Folders or a scheduled command-line job process them in sequence.

The PST is password protected. Remove the password in Outlook before converting, or supply the credentials if your workflow allows it. A protected container cannot be read without its password.

Old ANSI PST from a legacy system. reaConverter handles both ANSI and Unicode PST, so older Outlook archives are supported alongside modern ones.

Which reaConverter edition do I need?

Frequently asked questions

Do I need Microsoft Outlook to convert PST to PDF? No. reaConverter reads the PST format directly and does not launch or require Outlook, Exchange, or any internet connection. Everything runs offline on your machine.

Are email attachments preserved in the PDF? Yes. When you enable the embed-attachments option, each email’s original attachments are stored inside the PDF as openable files. In Adobe Acrobat Reader they appear in the Attachments panel, ready to open or save in their native format.

Can I convert a whole mailbox into a single PDF? Yes. The merge option combines every message in a PST into one continuous, searchable PDF, rather than producing a separate file per email.

Is this suitable for e-discovery and legal review? PST to PDF with embedded attachments produces a self-contained, searchable record that keeps the original files intact, which is what review and production workflows need. It runs offline, so sensitive mail never leaves your hardware.

Can I convert many PST files at once? Yes. reaConverter is a batch converter. Load a folder of PST files and it processes all of them in one pass. With Pro you can also automate the job through Watch Folders or the command line.

Can PST be converted to formats other than PDF? Yes. Besides PDF, you can render PST content to image formats such as JPG, PNG, and TIFF, all in batch.

Does the converted PDF keep the email text as searchable text? Yes. The message body is written as selectable, searchable text, so you can search across the whole archive inside any PDF reader.

Background — why we built this

This feature came from our support inbox, not a roadmap meeting. Over time we kept seeing the same request in different words: people sitting on a PST file that someone else needed, with no clean way to hand it over.

One message summed it up well:

“We have to send a former employee’s mailbox to our lawyers. They don’t use Outlook, and when we print the emails to PDF the attachments get lost. We need one file that has the emails and the actual attachments in it.”

That is the exact gap we set out to close. PST fit naturally into reaConverter’s existing pipeline, so we taught it to read mailboxes, write the message text as real PDF text, and, the part that took the most care, embed each attachment as an openable file inside the same document rather than flattening or dropping it. The result is a single PDF that anyone can open, search, and pull the original files out of, with no Outlook anywhere in the chain.

Conclusion

Converting PST to PDF used to mean opening Outlook and grinding through a mailbox one message at a time, hoping no attachment slipped through. reaConverter replaces that with a batch job: load your PST files, convert to PDF, and get back a searchable document with every original attachment embedded and openable. It works through the GUI for one-off jobs, through Watch Folders for automated archival, and through the command line for scheduled pipelines. No Outlook, no cloud, no lost attachments.

For legal teams, compliance and records staff, IT admins archiving mailboxes, and anyone who needs Outlook mail in a format the rest of the world can actually read, this is the workflow that removes the bottleneck.

The .geo file format belongs to Trumpf’s TruTops suite, the CAM software that drives TruLaser, TruPunch, and TruMatic sheet metal machines. It stores 2D part geometry for laser cutting and punching: outer and inner contours, bend data, material type, and thickness.

Outside the Trumpf ecosystem, almost nothing opens it. Generic CAD programs don’t recognize the format. Online converters either skip it or silently fail. Forum threads going back more than a decade end with the same two answers: go back to the shop that made the file, or license TruTops Convert from Trumpf.

Starting with version 8.0.200, reaConverter reads Trumpf GEO files directly and exports them to DXF, ready for AutoCAD, SolidWorks, Fusion 360, Bystronic BySoft, Amada AP100, or any other CAD or CAM system that speaks DXF.

Download reaConverter

Step-by-Step: GEO to DXF Conversion

The manual workflow takes under a minute, regardless of how many files are in the batch.

1. Install or Update reaConverter 8

Download the latest version from reaConverter.com. GEO support requires version 8.0.200 or later.

2. Add Your GEO Files

Drag your .geo files into the main window, or use Add Folder to load an entire parts directory at once. reaConverter processes large batches in a single pass with no file count limits.

3. Select DXF as the Output Format

In the output panel, choose DXF. Set your destination folder and any file-naming convention you want to apply.

4. Start Conversion

Click Start. reaConverter reads each GEO file, extracts the geometry, and writes a standards-compliant DXF.

Open the results in AutoCAD, LibreCAD, SolidWorks, Fusion 360, BricsCAD, or feed them directly into your CAM system.

Who This Is For

Job shops with used or second-hand Trumpf equipment. You bought a TruLaser off the auction market and inherited hundreds of legacy GEO parts. The machine runs. The files are locked inside a format your current CAD system doesn’t open.

Subcontract fabricators. A customer sends you GEO files because that’s what their engineering department exports. You run a Bystronic or an Amada. You need DXF.

Engineers migrating between CAM platforms. Your shop is standardizing on a different system, but you have years of part geometry sitting in GEO. Rebuilding from scratch isn’t an option.

Anyone who received a GEO file and needs to open it. Sometimes a customer, a vendor, or a colleague sends a file in a format their software exports by default. You don’t need to match their software stack. You need to read the file.

Batch Conversion for Legacy Libraries

Inherited parts libraries often contain hundreds or thousands of files. Manual conversion isn’t viable at that scale. reaConverter processes the entire folder in one pass and preserves the original directory structure if you want it to.

For shops that receive GEO files on an ongoing basis, such as subcontractors working with Trumpf-equipped customers, Watch Folders automate the conversion entirely. Point reaConverter at a hdd folder, set DXF as the output, and any GEO file that lands there gets converted automatically. Nobody has to launch the application or click anything.

Command-line support is available for IT teams integrating GEO conversion into ERP workflows, scheduled parts-library migrations, or customer file intake pipelines. Both features are available in reaConverter Pro.

Why GEO Is Hard to Convert

TruTops GEO is a proprietary 2D geometry format. It stores outer and inner contours, bend lines, cut types, and material properties in a structure that only Trumpf’s own software documents fully. There’s no public specification. The format was designed for round-tripping inside the Trumpf ecosystem, not for interoperating with third-party CAD.

That’s why most conversion attempts fail. Generic DXF libraries don’t understand the structure. Even technically capable users reaching for open-source tools come up empty.

reaConverter parses the GEO contour and geometry data directly and writes a clean DXF with the outlines preserved, ready to import into any standard CAD or CAM workflow.

Alternatives and Where Each Fits

TruTops Convert is Trumpf’s own conversion utility. It’s the right choice for shops running Trumpf machines and already using the TruTops suite. For everyone else — shops on other CAM platforms, subcontractors processing occasional incoming GEO files, or teams migrating away from TruTops — it’s more software than the job requires.

Re-exporting from the source CAD. The standard forum advice is to ask whoever generated the GEO file to export DXF instead. Sometimes that works. Often the source isn’t reachable, the customer isn’t responsive, or the parts were generated years ago by a shop that no longer exists.

Manual redrawing. Feasible for a handful of simple parts. Not feasible for a library of hundreds.

reaConverter sits in the space these options leave open: direct GEO reading, batch processing, offline, on any Windows machine.

Background

This feature was built in response to a direct customer request. A shop running Trumpf equipment hit a conversion failure on a specific GEO file and asked whether we could handle the format. We obtained sample files, built the extraction logic, and shipped support in reaConverter 8.0.200. The customer’s response after testing:

“FROM TRUMPF TO DXF. IS GO WELL. MASSIVE THANKS.”

If your workflow involves Trumpf GEO files and you need them as DXF — reliably, in batch, on Windows — reaConverter handles it.

Why convert DWG to DXF?

DWG is the native binary format of AutoCAD. It’s powerful, but proprietary. When you need to share drawings with partners who use SolidWorks, BricsCAD, FreeCAD, LibreCAD, or any non-Autodesk CAD tool, the proprietary DWG container becomes a bottleneck. DXF (Drawing Exchange Format) was designed specifically to solve this: it’s an open, documented interchange format that virtually every CAD program can read and write.

Common real-world scenarios where DWG → DXF conversion is essential:

• Cross-platform collaboration with partners who use SolidWorks, BricsCAD, FreeCAD, or other non-Autodesk CAD tools.
• CNC and laser cutter pipelines that accept only DXF input.
• Archival and compliance requirements where an open format avoids vendor lock-in.
• Automated production workflows where DWG files must be converted before entering a review or manufacturing system.

If you’re converting one or two files, an online tool might do. But when the job involves hundreds of drawings on a recurring basis, you need batch automation that runs offline, keeps your intellectual property on your hardware, and doesn’t require an expensive AutoCAD seat.

That’s where reaConverter comes in.

DWG vs DXF — quick reference

What you’ll need

• reaConverter Standard edition is enough for GUI batch conversion. For Watch Folders and command-line automation, you’ll need Pro. See the DWG to DXF conversion page for a quick overview of what’s supported.
• Your .dwg files. reaConverter supports all AutoCAD versions from R12 through the latest releases.
• No AutoCAD installation is required at any point.

Method 1 — Batch conversion in the GUI

This is the fastest way to convert a folder of DWG files interactively.

Step 1. Add your DWG files

Launch reaConverter and load your drawings. You can:

• Drag-and-drop files or entire folders from Windows Explorer.
• Use the Add Files or Add Folder buttons on the toolbar.
• Right-click DWG files in Explorer and choose Convert with reaConverter from the context menu.

reaConverter reads DWG natively, no CAD software needed. The file list shows previews, page count, and size for every drawing.

Step 2. (Optional) Configure DWG loading settings

Before converting, you can fine-tune how drawings are read:

• Layout selection: convert Model Space only, all Paper Spaces, or all layouts. Look for the DXF/DWG/DGN loading settings in the Settings panel on the left side of the main window.
• Grayscale: render the drawing in grayscale if color is not needed downstream.
• Layer extraction: split each layer into a separate output file.

These settings are especially useful when your DWG files contain multiple layouts and you only need the Model Space geometry.

Step 3. Choose DXF as the output format

In the bottom panel, set Save as → DXF. Click the gear icon next to DXF to open format-specific settings:

• DXF version: choose from AutoCAD 12, 13, 14, 2000, 2004, 2007, 2010, or 2013. If unsure, AutoCAD 2000 offers the best balance of compatibility and feature support.
• Units: millimeters or inches.
• Text handling: save as text or convert to polygons (useful when downstream tools have font substitution problems).
• Splines: enable or disable spline output.

Step 4. Set the destination folder

Choose where converted DXF files should be saved. You can keep the same folder structure as the source, save everything to a flat folder, or use reaConverter’s subfolder naming options.

Step 5. Click Convert

Hit Convert and reaConverter processes every file in the queue. The conversion log shows the status of each drawing. When done, click Show converted files to jump straight to the output folder.

Install reaConverter

Method 2 — Watch Folders (fully automated, zero clicks)

Watch Folders turn any Windows directory into a self-converting hot folder. Drop a DWG file in → a DXF file appears in the output directory. No interaction needed.

This is the ideal setup for:

• Engineering offices where designers save DWG files to a shared network folder and downstream teams need DXF.
• CNC / fabrication pipelines where an operator drops files for cutting.
• Any recurring workflow where manual conversion is a bottleneck.

How to set it up

1. Open reaConverter and go to Menu → Watch Folders → Add new folder…
2. Set the Source folder — this is the directory reaConverter will monitor, for example C:\CAD\DWG_inbox\.
3. Set the Output folder — for example C:\CAD\DXF_ready\.
4. Choose DXF as the output format and configure version, units, and other settings as described in Method 1.
5. Click Start Watching.

From now on, every DWG file that lands in the source folder will be automatically converted to DXF and placed in the output folder. It doesn’t matter how the file got there: copied manually, saved by a CAD tool, or synced from the network.

reaConverter keeps running in the background and can monitor multiple folder pairs simultaneously.

Tip: Use “Subfolder of source folder” output option combined with “Read subfolders” to maintain your directory structure while keeping originals separate from converted files.

For a detailed walkthrough, see the dedicated guide: A Beginner-Friendly Guide to reaConverter’s Watch Folders.

Method 3 — Command-line conversion

reaConverter Pro includes cons_rcp.exe, a full-featured command-line tool. It accepts the same parameters as the GUI and can be called from batch scripts, CI/CD pipelines, PowerShell, or Task Scheduler.

Basic single-file conversion

cons_rcp.exe -s "C:\Drawings\floorplan.dwg" -o "C:\Output\floorplan.dxf"

Batch convert an entire folder

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf

This converts every .dwg file in the source folder and saves each one as .dxf in the output folder.

With subfolders

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -read_subfolders 1

Set the output DXF version

Use -dxf_version to target a specific AutoCAD version:

Convert to AutoCAD 2000 DXF format:

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -dxf_version 4

Control layout output

Use -dxf_dwg_layout to specify which layout to convert:

Export only Model Space:

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -dxf_dwg_layout 1

Additional useful parameters

• -dxf_text 1 — preserve text as editable text (use 0 to convert text to polygons).
• -dxf_spline 1 — include splines in the output DXF.
• -dxf_units 1 — set output DXF units to millimeters (2 for inches).
• -dxf_dwg_gray 1 — convert the drawing to grayscale.
• -dxf_dwg_extract_layers 1 — extract each layer as a separate DXF file.
• -overwrite 1 — overwrite existing files instead of skipping them.
• /hide — run silently (no console window), ideal for scheduled tasks.

Full production example

Convert all DWG files (including subfolders) to AutoCAD 2000 DXF, Model Space only, with splines, millimeters as units, and overwrite existing output:

cons_rcp.exe -source_folder "D:\Projects\2026\CAD\" -source_ext dwg -dest_path "D:\Projects\2026\DXF\" -dest_ext dxf -read_subfolders 1 -dxf_version 4 -dxf_dwg_layout 1 -dxf_spline 1 -dxf_units 1 -dxf_text 1 -overwrite 1

Automate with Windows Task Scheduler

Save the command above as a .bat file and schedule it to run nightly, weekly, or at any interval. Add /hide to suppress the console window. Use > log.txt to capture the conversion log:

cons_rcp.exe -source_folder "D:\Projects\2026\CAD\" -source_ext dwg -dest_path "D:\Projects\2026\DXF\" -dest_ext dxf -dxf_version 4 /hide > "D:\Logs\dwg_to_dxf_log.txt"

For the full CLI reference, see: Command-line Interface for Developers.

Troubleshooting

Layers missing after conversion? Check the layout setting. If you’re exporting only Model Space (-dxf_dwg_layout 1) but your geometry lives in a Paper Space layout, switch to All Layouts (0) or All Paper Spaces (2).

Text looks wrong or is replaced by boxes? The target system may not have the fonts used in the DWG. Two options: set -dxf_text 0 to convert text to polygons (preserves appearance but loses editability), or install matching SHX / TTF fonts on the receiving machine.

File size significantly larger than original? This is expected. DXF (especially ASCII DXF) is less compact than binary DWG. If size matters, check whether your downstream tool accepts binary DXF. reaConverter outputs ASCII DXF by default for maximum compatibility.

Which reaConverter edition do I need?

Conclusion

Converting DWG files to DXF doesn’t require AutoCAD, doesn’t require uploading your proprietary drawings to the cloud, and doesn’t have to be a manual file-by-file task. reaConverter handles the job in three ways: GUI batch, Watch Folders, and command line. Whether you need a one-off conversion or a fully automated 24/7 pipeline, you’re covered.

For engineering firms, architecture studios, fabrication shops, and anyone working with CAD drawings at scale, this is the workflow that eliminates the bottleneck. Already know what you need? Head straight to the DWG to DXF converter page to download or try online.

Extract individual frames from embedded multiframe DICOM — no scripting, no manual splitting

Multiframe DICOM files pack dozens or even hundreds of image frames into a single container. CT volumes, MRI sequences, ultrasound cine loops, and nuclear medicine studies are commonly stored this way. When a downstream system, analysis pipeline, or colleague expects one-image-per-file DICOM, you’re stuck — most conversion tools either ignore the extra frames or don’t offer DICOM as an output format at all. The usual alternatives are writing Python scripts with pydicom, wrestling with dcmtk command-line utilities, or paying for specialized medical imaging software.

A recent customer request summed up the problem:

“My goal was converting from an embedded DICOM multiframe file to multiple single-frame files, but there was no such option.”

Starting with version 8.0.200, reaConverter supports direct DICOM to DICOM conversion, including full extraction of frames from both classic and Enhanced multiframe DICOM files.

Download reaConverter

Classic vs. Enhanced Multiframe DICOM

Multiframe DICOM comes in two flavors. Classic (Simple) Multiframe is the older format where all frames share one set of metadata(common in legacy archives and ultrasound systems). Enhanced Multiframe is the modern standard for CT and MRI, where each frame carries its own metadata through Functional Group sequences — more capable, but significantly harder for third-party software to parse. Most DICOM tools either don’t support Enhanced multiframe at all, or only extract the first frame. If your file contains multiple images and you need to separate each frame into its own DCM file, reaConverter handles both types.

Who This Is For

Radiologists and imaging departments — Separate multiframe CT, MRI, or ultrasound studies into individual slices for viewers that require single-frame input. Prepare data for second opinions or external consultations where the receiving system doesn’t support multiframe.

Medical researchers and AI developers — Convert multiframe studies into single-frame datasets for machine learning training and image analysis pipelines. Most ML frameworks expect one image per file; multiframe DICOM breaks that assumption.

PACS engineers and healthcare IT — Migrate imaging data between systems with different multiframe support. Normalize mixed archives. Handle extensionless DICOM files exported from older equipment without manual preprocessing.

Step-by-Step: Multiframe DICOM to Single-Frame DCM

Follow these steps:

1. Install or Update reaConverter 8

Download the latest version from reaConverter.com. DICOM-to-DICOM conversion requires version 8.0.200 or later.

2. Add Your Multiframe DICOM Files

Drag files into the main window, or use Add Folder to load an entire study directory.

reaConverter detects DICOM files automatically — with standard extensions (.dcm, .dic, .dicom) or without any extension at all, based on the DICOM header. Extensionless DICOM is extremely common in PACS exports and scanner-generated archives. No renaming needed.

3. Select DCM as the Output Format (DICOM to DCM Conversion)

In the output format panel, choose DCM. This is a DICOM-to-DICOM conversion: the input is your multiframe file, the output is a set of individual single-frame DICOM files.

4. Start Conversion

Click Start. reaConverter will:

• Detect the multiframe structure inside each input file
• Extract every frame
• Save each frame as a separate single-frame DCM file

Output files are named sequentially:

pacient_scan_001_frame_001.dcm
pacient_scan_001_frame_002.dcm
pacient_scan_001_frame_003.dcm
...

No additional settings, filters, or scripting required.

Clinical-Grade Output: UIDs and Header Remapping

Splitting a multiframe file is only half the job. For the output to work in a PACS or treatment planning system, two things have to happen under the hood — and most general-purpose converters skip both.

Unique SOPInstanceUID per frame. Every DICOM instance needs its own globally unique SOPInstanceUID. reaConverter generates a fresh, standards-compliant UID for every single-frame file it writes, so PACS systems don’t reject, overwrite, or silently deduplicate the output.

Functional Group Sequence remapping. Enhanced multiframe stores per-frame metadata inside Shared and Per-Frame Functional Group Sequences. Legacy single-frame readers don’t know where to look for it. reaConverter extracts those attributes and writes them into the top-level header of each output file, producing legacy-compatible DICOMs that load correctly in older viewers and PACS archives.

These two steps are the reason teams often fall back to command-line tools like dcm4che‘s emf2sf. reaConverter delivers equivalent output through a standard Windows GUI, with batch processing and Watch Folder automation on top.

Beyond Multiframe Extraction

reaConverter doesn’t only split multiframe DICOM into single-frame DCM. You can also:

• Convert multiframe DICOM to JPEG, PNG, TIFF or PDF for visualization, presentations, or reporting
• Batch-process large imaging archives with hundreds of studies
• Convert other medical and non-medical formats to DCM

Save Hours with Automatic Conversion

The four steps above work when you need to convert a batch of files once. But in a busy radiology department or research lab, multiframe DICOM files keep arriving — from scanners, PACS exports, external referrals. Converting them manually every time means someone has to stop what they’re doing, and that someone usually has patients waiting.

Watch Folders eliminate that step entirely. You pick a folder on your computer, tell reaConverter what format you want, and that’s it. From that point on, any file that lands in that folder gets converted automatically. No clicks, no application window, nothing to remember.

Here’s what that looks like in practice: your MRI scanner exports a multiframe Enhanced DICOM study into a shared network folder. Within seconds, reaConverter detects the new file, splits it into single-frame DCMs, and places the results in your output folder — ready for your PACS, your analysis pipeline, or your colleague down the hall. Nobody had to open anything or press any buttons.

Setting it up takes about two minutes:

1. In reaConverter Pro, go to Menu → Watch Folders → Add New Folder
2. Point it at your input directory
3. Choose DCM as the output format
4. Set a destination folder

That’s the entire configuration. It runs quietly in the background from that point forward.

For a radiologist reviewing 20–30 studies a day, or a research team processing imaging data from multiple sites, this turns a recurring manual task into something that simply doesn’t exist anymore. That’s one less thing standing between a scan and a diagnosis.

Command-line support is also available for IT teams who want to integrate DICOM conversion into scripts, scheduled tasks, or PACS migration workflows. Both options are available in reaConverter Pro.

Background

This feature was built in response to a direct customer request. A user reached out explaining that they needed to extract individual frames from embedded multiframe DICOM files, and couldn’t find a way to do it in reaConverter or anywhere else without resorting to scripting.

We obtained sample files covering both classic and Enhanced multiframe DICOM, including extensionless files from PACS exports, and built extraction logic that handles all of these cases reliably. DICOM-to-DICOM conversion shipped in reaConverter 8.0.200.

Full support for Enhanced multiframe DICOM extraction is still uncommon, even in professional medical imaging software. Many tools handle classic multiframe but fail on Enhanced, or extract only the first frame, or simply don’t offer DICOM as an output format. reaConverter fills that gap: no DICOM dictionary edits, no Python scripts, no per-frame configuration. Load the file, pick DCM, click Start.

If your imaging workflow involves multiframe DICOM files and you need them split into individual frames, reliably, in batch, with no manual intervention, reaConverter handles it.

Get reaConverter and split your first multiframe DICOM in seconds.
