Batch processing in Gimp - how it works
You can also use the free Gimp image processing software to automate tedious routine tasks using batch processing. However, this feature is not part of the standard Gimp installation, but must be supplemented with a plugin. Once that's done, you can easily rotate, scale, crop, sharpen, blur, or rename 100 photos in one go.
Batch processing super fast: processing photos in Gimp
You don't have to write a script yourself to scale a large amount of photos to a certain size with one command, for example. The plugin "David's Batch Processor (DBP)" does this and many other tasks quickly and reliably. You can download the plugin from this page. If you are not sure how to install the plugin, just read the tip Gimp: Install plugins - how it works.
- After installing the plugin, you will find the "Batch Process" entry under the "Filter" menu item. One click opens David's Batch Processor.
- With the button "Add Files" on the working surface of the plugin you can browse through the pictures on your computer and select the ones you want to edit. With "Add" you add the images to your stack. You can also remove individual pictures ("Remove Files") or the entire list ("Clear List") later. When your selection is complete, close the window.
- The various functions of batch processing can be called up via tabs in the menu bar. You can rotate, blur, scale, crop, sharpen and edit your images. To be able to use the tools, you have to activate them. To do this, check the "Enable" entry.
- This allows you to largely use all the functions that Gimp offers to a large number of images. Of course, you can also use the tools at the same time, e.g. scaling images to a certain size, increasing the brightness and sharpening them. If you have set all values, you can call up a preview of the processed images via "Test".
- Before you start the final editing process, you must set the output format for the images on the "Output" tab. All common image formats such as .JPG, .PNG, .TIFF are available here. Once this is done, start processing via "Start". The original images are then overwritten with the new values.
- For example, if you only want to create smaller images for the web, it makes sense to keep the originals. In this case, go to the "Rename" tab before you start batch processing. There you can add or add your name to a picture. In this menu there are further possibilities for image processing, for example the conversion to black and white images.
