Gifski is a top-quality GIF encoder that stands out for creating animated GIFs with thousands of colors per frame. It is based on pngquant and offers efficient cross-frame palettes and temporal dithering. Although it’s primarily a CLI tool, it can be compiled as a C library for easy integration into other applications. To use Gifski, export the video as PNG frames and then convert them to a GIF using commands like gifski -o anim.gif frame*.png. The tool also offers options to resize frames and adjust quality settings for smaller GIF files while keeping quality in check. Installing and building the tool require up-to-date Rust versions, and additional video support may be enabled using ffmpeg. Cross-compliation for iOS is available for seamless integration with Apple platforms.
