Are you worried that your photographs might be used without permission once you post them online? The easiest way to make sure your author rights are protected is to add a visible watermark on your photos. This is the equivalent to adding a signature — it can be your name or the initials of your name, your logo, a quote, or any other type of text or image you find suitable. Watermarking is also a good way to keep track of your photos; you can use it to create date stamps or to mark EXIF or META data on your photos.

What is the easiest way to apply watermarking on all your desired photos at once, thus avoiding repetitive and dull operations? Instead of searching for specialized software, that might be expensive and/or difficult to use, why not use reaConverter’s image editing features for watermarking? This high quality and user-friendly software not only works as a powerful batch conversion program, supporting over 500 image formats, but can also function as a watermarking tool for your images. reaConverter Lite edition is completely free and supports batch image watermarking features.

Install reaConverter Lite

How does it work?

Open reaConverter to select all the images you intend to watermark and add them manually or drag-and-drop them to the file list.

Then move on to the Edit images tab, where you have a wide variety of image editing options available. Take a few moments to browse through the actions and pick one of the four watermarking options:

Image Watermark

Take any image from your computer and position it anywhere you like on your photo. For example, you can place a small and discrete logo in one of the photo’s corners, or you can add a large one, placed transparently over the entire image. reaConverter allows you to rotate or resize the watermark image, as well as use the Opacity feature to control its transparency. You can always check how the image will look like in real time by ticking the Preview button, in the upper right corner of this window.

Text Watermark

Place your name, your initials or any other text you think is relevant on your photos. ReaConverter allows you to customize its font and size, as well as add the copyright symbol and the hash sign if you choose to. You can also use the text watermark feature to add a date stamp on every one of your photos, the image description or a page number. As in the previous case, you can position and rotate the text, control its transparency and preview how it will look like on the photograph.

Dynamic Watermark

In case you have an entire series of photos that you want to watermark and you don’t plan to use an identical text for each of them, reaConverter allows you to place customizable info on each photo. You can opt for inserting the image file name, it’s EXIF ingormation as watermark, copyright information or description, the full date and time when the photo was taken, as well as several other different details connected to each different photograph.

Primitive Drawings

Also described as basic elements used in computer graphics to help in structuring more complex images, primitives can take the form of lines, squares, circles and other similar shapes. reaConverter Lite includes a simple and intuitive feature for watermarking with primitive drawings, that also involves a rich array of customizing tools.

Apply Watermarks and Save the Result

In case you are using reaConvert only as an free watermarking tool, in the final step of the conversion process, pick the output format of the image to be the same as the input format. In case you want to take advantage of the conversion services offered by this software too, pick the desired extension from buttons at the bottom.

Then press the Start conversion button and quickly enjoy your watermarked pictures!

Advanced users can perform image watermarking using command line interface or DLL in manual, automated or scheduled mode. You are welcome to contact our technical support when you have any questions about reaConverter.

If you want to make sure your copyrights are protected and no one will use the images you create without explicit permission, watermarking your images is the best solution. But this implies editing each image so that it includes a personalized text or image which appears transparently, with customizable size and position. Many people might find that to be a complicated task, involving a series of repetitive operations.

However, we are convinced watermarking your images shouldn’t be a difficult, time-consuming or costly process. And for this reason we recommend using ReaConverter Pro for adding watermarks, especially in case you are a developer or an advanced user who would like to integrate this feature in his own customized solution. As opposed to many other converters, reaConverter Pro not only supports a GUI interface, but can also be operated through command-line or Watch folder. Which means it can help you integrate a large variety of image editing features in your very own custom solution.

How can you watermark a series of images using command line? Just follow these easy steps:

Create action file

Create a file with the .act (action) extension, which includes the Watermark action. How? Start the conversion process normally, by opening reaConverter and moving directly to the Edit images tab. Click + add action button and choose Watermark from the dropdown menu. After you pick the type of watermark you intend to use (image or text) and its features, use Save action file as… What will result is the .act file you will need in order to process this feature through command-line. Make sure you remember where you saved it.

Run CMD

Open the cmd tool or a third party application that enables you to use it. Here you can issue commands written as text lines. Though more difficult to use than the GUI (graphical user) interface – because it requires more knowledge about how to write command lines and thus it is addressed mainly to developers and advanced users, command line is very effective when a complex set of tasks is involved, such as watermarking a large number of images.

Start cons_rcp.exe

Use reaConverter’s command-line tool, cons_rcp.exe, to process over 500 images file formats, including PDF, JPG, TIFF and many others. Make full use of the .act file you have created and include Watermarking in your own customized software solution.

Example

Here is the example on how to apply watermark with text on your images:

cons_rcp.exe -s "C:\Path_to\input_file.jpg" -o "C:\Path_to\output_file.jpg" -text_watermark t"Text Watermark Here" pos50x50% op100 fn"Arial" fs24 b


Watermarking with image:

cons_rcp.exe -s "C:\Path_to\input_file.jpg" -o "C:\Path_to\output_file.jpg" -image_watermark p"C:\Path_to\watermark.png" pos10x10% op50 rot90 mt


Dynamic watermarks:

cons_rcp.exe -s "C:\Path_to\input_file.jpg" -o "C:\Path_to\output_file.jpg" -text_watermark datetime pos50x50% op100 fn"Arial" fs24 b


You can also watermark images with primitive drawings:

cons_rcp.exe -s "C:\Path_to\input_file.jpg" -o "C:\Path_to\output_file.jpg" -line pos50x50 size100x100 rgb(66,137,212) p2 aa
