About AVIF to WebP

Convert AVIF, the AV1-based format, into WebP for wider app and editor support. WebP is handled by far more tools than AVIF while still keeping files small, and transparency comes through intact so logos and graphics stay clean.

The decode and re-encode both run entirely in your browser with WebAssembly codecs. Your AVIF file never leaves your device, so the conversion stays completely private.
