How to convert AVIFS to WEBP
- Add your .AVIFS file - drop it in the box above or click to browse.
- Convert it to .WEBP in a few seconds.
- Download your new .WEBP file.
What to expect
- This is a lossy-to-lossy re-encode, so a small amount of AVIF detail is lost unless you force
-lossless 1. - AVIF generally compresses better than WebP, so the WebP may be slightly larger at matching quality.
- FFmpeg must be built with both libavif (to decode) and libwebp (to encode) support.
Frequently asked questions
Does WebP keep the transparency?
Yes, animated WebP supports an alpha channel, so transparent AVIF areas are preserved.
Will the WebP be smaller than the AVIF?
Not usually - AVIF is a more efficient codec, so expect a similar or slightly larger WebP.
How do I make it loop forever?
Add
-loop 0 in FFmpeg, which sets infinite looping for the animated WebP.Can I convert losslessly?
Use
-lossless 1 with libwebp_anim, but the output file will be considerably larger.
