How much smaller will AVIF be than my WebP file?

Typically another 20-30% smaller at the same visual quality, since AVIF is currently the most efficient mainstream image format.

Is it worth converting if WebP already works fine for me?

Only if you serve a lot of images and bandwidth or storage matters — otherwise WebP is already a strong, widely supported choice.

Can I convert several WebP files to AVIF at once?

Yes. Add a whole batch of WebP files together and click Convert — each one becomes its own AVIF in a single pass, with no limit on the number of files.

Does every browser support the AVIF I get back?

Nearly all current browsers do, but a few older versions and some image-editing tools still do not open AVIF at all. Check where the image needs to display before replacing every WebP on a site with AVIF.

Will the AVIF keep the WebP's transparency and animation?

Yes. AVIF supports both an alpha channel and animation just like WebP, so a transparent logo or a looping animated WebP converts with those features intact rather than being flattened.

Does converting from WebP to AVIF lose any quality?

If the source WebP is lossy, re-encoding to lossy AVIF adds one small additional generation step; at standard quality settings it is not visible, but repeated round-trips between lossy formats should be avoided, especially for images you plan to keep re-saving.

When should I NOT bother converting to AVIF?

Skip it for a master file you plan to keep editing, since every lossy re-encode discards a little data. AVIF is best applied as a final delivery step for images that are done being edited and just need to load fast on a live website.

About WEBP and AVIF

Key things to know before you convert WEBP to AVIF:

WEBP

WebP is Google's web image format: ~25-35% smaller than JPG at the same quality, with support for transparency and animation. All modern browsers display it; some older software still does not.

AVIF

AVIF is the most efficient mainstream image format, built on the AV1 codec: about half the size of JPG. Supports HDR, transparency and animation. Encoding is slower and tool support is still maturing.
