Gifski is a macOS app that converts videos to high-quality animated GIFs.
The tool solves the problem of creating GIFs that retain visual quality and color depth by wrapping the gifski encoder, which uses pngquant's cross-frame palette optimization and temporal dithering to produce animated GIFs with thousands of colors per frame at up to 50 FPS. For users who need smaller files, a quality slider leverages gifsicle to reduce file size at the cost of visual fidelity. The app accepts all video formats that macOS supports, including H264, HEVC, and ProRes, and provides controls for dimensions, speed, frame rate, quality, cropping, and looping.
Gifski suits macOS users who need to convert videos to GIFs for design portfolios, documentation, or social sharing where color depth and frame rate matter. The app integrates with macOS through a share extension and system service, allowing quick conversion from any app with a compatible video file. It also offers a bounce mode that creates yo-yo playback effects by reversing frame sequences, though this doubles file size.
The project maintains backward compatibility across multiple macOS versions through archived releases, with older builds available for users on earlier operating systems. A non-App Store distribution channel is provided for users unable to access the App Store, updated periodically to ensure continued availability.
