AVIF is a modern image format based on AV1. It compresses 30–50% better than WebP at similar quality and supports animation, alpha and HDR.

Which browsers can decode AVIF here?

Chrome, Edge and Firefox 113+ decode AVIF natively. Safari 16+ supports still AVIF; animated AVIF support is improving.

Are my files uploaded?

No. Decoding happens in your browser; encoding uses ffmpeg.wasm locally.

AVIF to GIF Converter

Decode an AVIF image (still or animated) in your browser and re-encode it as a universal animated GIF. AVIF is far more efficient than GIF, but legacy software still requires GIF — this is the bridge.

Frequently asked questions

Why is my browser rejecting the AVIF?

Older browsers (Safari ≤ 15, Firefox ≤ 112) lack AVIF decoding. Update your browser or use Chrome / Edge.

Does this preserve HDR / 10-bit AVIF?

GIF is SDR 8-bit only, so HDR detail is mapped down to standard range when re-encoding.
