gifski is a high-quality GIF encoder based on pngquant's libimagequant, using cross-frame palettes and temporal dithering to produce smooth animated GIFs with thousands of colors per frame. It ships as a CLI tool with GUI variants for Windows and macOS, and can also be compiled as a C library for embedding in other applications.
Use cases
- convert a video to an animated gif
- make high-quality gifs from png frames
- compress gif animations under a file size limit
- encode gifs with thousands of colors instead of dithered mess
- embed a gif encoder in an app via C FFI
- resize and downscale gif animations
When to choose
- you need the best possible quality from the GIF format
- you're converting video clips or PNG frame sequences to GIFs
- you need a scriptable CLI or an embeddable C library
When to avoid
- you want modern formats like WebP, APNG, or MP4 which offer far better quality per byte
- you only need simple GIF decoding rather than encoding
