WebP to AVIF Converter
Convert WebP to AVIF online for free — even smaller files than WebP, transparency preserved. Works cross-browser via a built-in encoder; nothing uploaded, batch convert.
100% private — your images never leave your browser. Conversion happens on your device; nothing is uploaded.
AVIF is a modern format that’s typically 30–50% smaller than JPG at the same quality. Conversion happens in your browser — where your browser can’t write AVIF directly, a lightweight in-browser encoder is used, so it still works in every modern browser. Nothing is uploaded, and metadata is stripped on re-encode.

Is AVIF actually smaller than WebP?
Usually yes — at equal quality AVIF tends to be smaller than WebP, which is the main reason to convert.
Does WebP to AVIF preserve transparency?
Yes — the alpha channel is kept, so transparent areas stay transparent.
What happens to an animated WebP?
The first frame is converted to a still AVIF; animation is not preserved.
Do all browsers support AVIF like WebP?
Almost — modern browsers support AVIF, but older Safari and legacy Edge don't, whereas WebP support is slightly wider.
Is there quality loss going from WebP to AVIF?
Both are lossy formats, so pick a quality that looks right; AVIF is efficient and looks great at 60%+.
