Will the AVIF file have transparency?

Not automatically — JPG images carry no alpha channel, so the converted file is fully opaque. The difference is that AVIF can store transparency, so after converting you can open the image in an editor and erase the background without another format change.

Will quality drop when re-encoding JPG as AVIF?

Slightly, in principle. JPG and AVIF are both lossy formats, and every re-encode discards a little more data — the digital equivalent of photocopying a photocopy. In practice, keeping the quality slider high makes the difference imperceptible. Just avoid converting the same image back and forth repeatedly.

Do I need a particular browser to convert to AVIF?

Yes — the encoding runs in your browser, and in-browser AVIF encoding is currently available in Chromium-based browsers such as Chrome, Edge, Brave, and Opera. If your browser cannot encode AVIF, FileMorf reports an error instead of silently producing a different format. The finished files display in Chrome, Firefox, Edge, and Safari 16 or later.

How much smaller will the AVIF file be?

A clearly smaller file at comparable visual quality is a common result, and AVIF renders smooth gradients with less banding than JPG.
