GIMP 3 Export Plugin

A plugin for GIMP 3 to batch export images, optimized for web development. This plugin allows you to quickly render images in multiple resolutions and formats.

Features

• Batch export images in JPEG, PNG, WebP, and AVIF formats
• Supports resizing into different aspect ratios with cropping
• Process multiple images at once

Installation

Place the script in your GIMP plug-ins folder:

Windows:
C:/Users/AppData/Roaming/GIMP/3.0/plug-ins/batch-export/batch-export.scm

MacOS/Linux:
~/Library/Application Support/GIMP/3.0/plug-ins/batch-export/batch-export.scm

Restart GIMP afterwards.

Usage

1. Open the image/s in GIMP you want to export.
2. Go to Batch Export > Render Images in the menu bar.
3. Enter desired resolutions:
   • Width only (e.g., 500) keeps the aspect ratio.
   • Width x Height (e.g., 800x600) crops the image before resizing.
   • Separate multiple resolutions with a comma (e.g., 500,800x600).
4. Toggle Select All Open Images if needed.
5. Click OK, and images will be saved in the same folder as the original, with new widths appended to the filename (e.g., image_500.jpg).

Customization

You can modify the script by simply opening it in an IDE or text editor. Especially the export options for the formats can be easily tweaked.
