Gifski

Gifski is a GIF encoder by Kornel Lesiński that works around the format's limits with pngquant palettes, temporal dithering and lossy LZW compression, reaching thousands of colours per frame. It is free software, available as a Mac app by Sindre Sorhus, a Windows app, a command-line tool and a library with a C interface for other apps. Designers use it to turn screen recordings of interactions into GIFs that stay smooth and small enough for upload limits.
