What it is
Gifski is a GIF encoder that turns video clips into smooth animations. It uses pngquant palettes and temporal dithering to produce frames with thousands of colors, alongside lossy LZW compression, temporal smoothing, and denoising. Users can resize animations and adjust compression to fit upload size limits. Quality is prioritized over small output by default; reducing dimensions, frame rate, or quality can make GIFs smaller. The site links to a free Windows graphical app and a macOS app, while command-line binaries are available for Linux, macOS, and Windows. The command-line workflow converts video through PNG frames, so ffmpeg may be needed to extract them. The macOS app includes trimming, cropping, dimension and speed controls, preview, looping and bounce options, and sharing integrations. It converts video rather than creating GIFs from added text or other elements, and it does not support QuickTime Animation. The library is open source for free software use; closed-source apps or services require a commercial license.
