2025-10-28 (GIMP 3.0)

The old BIMP-plugin doesn't work with GIMP 3.0.
Alternative plugin is Batcher: https://kamilburda.github.io/batcher/

-Install Batcher plugin with instructions on its website
-Restart GIMP, the File-menu now has option "Batch Convert"
-Batcher works very much the same as the old BIMP-plugin

Basic batch editing is easy with Gimp!

Download this plugin for gimp:
BIMP. Batch Image Manipulation Plugin: http://registry.gimp.org/node/26259
-The plugin has a neat installer, install the plugin
-Next, open gimp, open File menu and select "Batch Image Manipulation..."
-Select your effects, select files or folders
-Click apply!

Note: the editor may not always overwrite files, create a new folder and select it as your output folder to be sure!


Example usage:

Cropping
I have a lot of icon images which have borders around the actual icon. I wish to remove the borders. This is a lot of work to do by hand so we use the Batch Image Manipulation Plugin!
-I open the Batch Image Manipulation Plugin from the File menu in Gimp
-I click "Add" and select Crop
-In the Crop tools properties I select "Manual Crop (pixel values)" and input 74 by 74 pixels (I measured this beforehand)
-I leave the "Start from:" to it's default setting (it's Center by default)
-Then I select my folder full of icons and click "Apply"
-Success! The borders are gone and I have a set of nice icons
