Frequently Asked Questions
Why convert WebP to AVIF?
AVIF is the newer format and usually compresses a little better than WebP, so the file gets smaller again while quality stays close. Both keep transparency.
Does it keep transparency?
Yes. AVIF supports an alpha channel, so a transparent WebP background stays transparent in the AVIF.
Which browsers can create AVIF here?
Encoding runs in your browser, so you need Chrome 100 or newer, or Edge 100 or newer. If your browser cannot encode AVIF, the tool tells you instead of saving a wrong file.
Will I lose quality?
AVIF is saved with a quality setting, so there is some loss, but at this setting it is hard to see while the file gets smaller.
Is my image uploaded anywhere?
No. Everything runs in your browser, so the file never leaves your computer and the tool works offline.
Does it keep the same dimensions?
Yes. The pixel width and height stay identical; only the format and file size change.
Is AVIF always smaller than WebP?
Usually a little smaller at the same quality, but it depends on the image. The tool shows both sizes so you can compare.
Does it work on a phone?
Yes, on a recent Chrome or Edge mobile browser, with nothing to install.
