ImageWorsener is a cross-platform command-line utility and library for image scaling and other image processing. It has full support for PNG, JPEG, BMP formats, experimental support for WebP, read-only support for GIF, and limited support for some other image formats. It’s not as fast or memory-efficient as some utilities, but it’s very accurate.
It is free software, licensed under an MIT-style license.
