Does converting WebP to AVIF keep transparency?

Yes. Both WebP and AVIF store a full alpha channel, and FileMorf preserves it exactly — anti-aliased edges, soft shadows, and semi-transparent pixels all survive the conversion.

Will quality drop when re-encoding WebP as AVIF?

Slightly, in principle. WebP 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?

Typically smaller again than the WebP source at similar quality — a difference worth having on high-traffic pages.

What about animated WebP files?

An animated WebP is decoded as its first frame, so the output is a single still image. Static WebP files — the vast majority — convert in full.

Questions about WebP and AVIF.

Check the format behavior, limitations, and follow-up options before processing a real file.

If you already serve WebP, AVIF is the next step down in size — often smaller again at comparable quality, with the same alpha transparency support. It is worth doing for high-traffic pages; keep WebP as the fallback for older browsers.
