AVIF to WebP
Nearly as small, more widely accepted — never uploaded.
How it works
Three steps, and nothing leaves your device.
-
1
Drop the AVIF in
It is decoded in the page; nothing is sent anywhere.
-
2
It is encoded as WebP
At 92%, with transparency carried across.
-
3
Download the WebP
Still small, and accepted in more places.
The middle ground between AVIF and JPG
- This is the compromise conversion. AVIF is the smallest and the least widely supported; JPG is the most supported and much larger. WebP sits between them — noticeably smaller than JPG, and readable by far more software than AVIF.
- Transparency survives, which JPG would not allow. Both formats have a real alpha channel, so a cut-out keeps its transparent background.
- The file will grow, but not dramatically. AVIF is more efficient than WebP, so expect some increase. It is a much smaller penalty than converting all the way to JPG or PNG.
- It is a second lossy encode. Both formats are lossy, so the AVIF remains the better master. At 92% the extra generation is not visible on a photograph.
Frequently asked questions
Why not just convert to JPG?
WebP is meaningfully smaller than JPG and keeps transparency. Choose JPG only when something refuses WebP.
Is transparency kept?
Yes. WebP has a full alpha channel.
How much bigger will it be?
Somewhat larger than the AVIF, far smaller than a JPG or PNG.
Is my image uploaded?
No. It is converted in your browser.
