GraphicsMagick vs Light Image Resizer

GraphicsMagick is free image-processing software with command-line tools, programming interfaces, and graphical interfaces for image conversion, editing, and 2D vector rendering. It can resize, rotate, sharpen, reduce colors, apply effects, compare and composite images, create montages and GIF animations, and draw shapes or text. It reads, writes, and manipulates images in more than 92 major formats, including AVIF, GIF, HEIC, JPEG, JPEG-2000, JXL, PNG, PDF, TIFF, and WebP. The software also supports very large images, including gigapixel-size files. OpenMP multi-threading can scale CPU-bound processing across processor cores when built with a compatible compiler. Interfaces include C, C++, Lua, Perl, PHP, Python, Tcl, Ruby, Windows .NET, and Windows COM, alongside the command line. Some format support relies on external components, such as Ghostscript for PDF and PostScript or dcraw for camera RAW formats. GraphicsMagick is distributed under an MIT-style license for open-source, proprietary, or GPLed applications. The project lists version 1.3.48, released July 23, 2026, as current and recommends updating because significant issues are addressed in almost every release.
