Convert WebP to AVIF
Free, instant WebP to AVIF conversion - processed entirely in your browser, nothing is uploaded.
If you are chasing the smallest possible web images, AVIF typically shaves another 10-30% off already-optimized WebP files at the same visual quality. It is a sensible upgrade for high-traffic pages where every kilobyte of image weight affects load time. Keep serving WebP as a fallback for the shrinking set of clients that don't handle AVIF - and note that where a browser can't encode AVIF, this tool's WebP and JPG outputs remain available.

Frequently asked questions
Is it worth re-encoding WebP as AVIF?
For large photographic images on busy pages, yes - the extra savings are real. For small icons and graphics the difference is a few KB, and re-encoding an already-lossy file can soften fine detail.
Does converting between two lossy formats hurt quality?
Each lossy re-encode discards a little information. Convert from the highest-quality source you have; if you only have the WebP, keep the quality high to minimize generational loss.
