Frequently asked questions
Why convert AVIF to WebP instead of JPG?
WebP keeps transparency and produces smaller files than JPG. Choose JPG only when the destination does not accept WebP.
Will the WebP be bigger than the AVIF?
Typically yes, by somewhere around 20 to 40 percent, because AVIF is the more efficient format. It will still be smaller than a JPG of the same photo.
Is the conversion slow?
No. WebP encodes quickly, so even large batches finish faster than conversions to AVIF.
Are my AVIF files uploaded anywhere?
No. The conversion runs in your browser using WebAssembly, so your AVIF files stay on your device. There is no signup, no watermark and no cost, and you can convert a whole batch and download it as a zip.
About AVIF to WebP
AVIF to WebP trades a little compression for much broader support. WebP has been in every major browser for years, opens in more editors and is accepted by more platforms than AVIF, while still being much smaller than JPG or PNG. It also supports transparency and, unlike AVIF, encodes quickly, which makes it practical for a batch of images.

Both formats are lossy for photographs, so converting from AVIF to WebP compresses the picture a second time. At normal viewing size the result is usually indistinguishable, but if you still have the original, convert from that. Expect the WebP to come out somewhat larger than the AVIF, since AVIF compresses better. Transparency is preserved. An animated AVIF becomes a still image from its first frame. Metadata is removed.
AVIF is lossy or lossless, compressed with AV1; WebP is either lossy or lossless, depending on how the file was saved. Both formats can store transparency, so transparent areas in the AVIF file stay transparent. AVIF files can be animated, but the result is a still image made from the first frame. For scale, a 12-megapixel photo is typically 1 to 2.5 MB as AVIF and 1.5 to 3.5 MB as WebP. Compatibility: Every current browser displays it. Some older desktop software, email clients and upload forms still reject it.
