Why convert GIF to HEIF?

Introduced in 1987 by CompuServe, GIF was great for its time. But HEIF (created in 2015 by MPEG Group) offers lossy compression and 10-bit HDR – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize

Only the first frame of animated GIF files will be converted
