Why we included this project
ImageMagick has been the default answer for scriptable image work for a long time, and it still is. It reads and writes a couple hundred raster formats, and the command-line tools handle resizing, cropping, compositing, and filtering without needing a GUI or a heavyweight runtime. The same operations are available through C, Python, and other language bindings, so you can call them from an application or a batch job. Since everything runs locally with no external service involved, it fits naturally into self-hosted pipelines for jobs like generating thumbnails or normalizing user uploads. It is written in C and runs on Linux, Windows, and macOS, which is part of why it keeps showing up in production scripts.
