A script that automatically downscales images based on custom presets and more.
Originally developed to downscale anime/vidya screenshots "on the fly". Features image cropping and WebP conversion!

Features:

  • Automatic image downscaling based on custom presets with a variable image quality.
  • Automatic WebP conversion to either JPEG or PNG.
  • "Quick Convert" feature, that effectively reduces image filesize without resizing the image. Very useful when images exceed the 4chan filesize limit.
  • Simple image pre-viewer.
  • Image cropping tool.

2.5 changes:

  • Replaced the useless auto PNG conversion with auto WebP conversion.
  • Image preview header now displays the correct file type after conversion.
  • Some minor UI adjustments.

Requires 4chan X.
Tested on Firefox and Librewolf* using Tampermonkey and Violentmonkey. Does not work with Greasemonkey.
*If images appear to be broken after conversion, you need to set "privacy.resistFingerprinting" to false in about:config.
