Gifski

What Gifski 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, and supports lossy LZW compression, temporal smoothing, and denoising. You can resize an animation and adjust compression to meet file-size limits. By default, Gifski prioritizes quality over smaller output; reducing dimensions, frame rate, or quality can help shrink files. The site links to a free Windows graphical app and a macOS app, and command-line binaries are available for Linux, macOS, and Windows. In the command-line workflow, video is converted through PNG frames, so ffmpeg may be needed to extract them. The macOS app includes trimming and cropping, dimension and speed controls, previews, looping and bounce options, and sharing integrations. It converts video rather than creating GIFs from added text or other elements, and does not support QuickTime Animation. The library is open source for free software use; closed-source applications or services require a commercial license. Gifski is free, with video import supported on Windows, macOS, and Linux.
