Re encode AVIF to WebP for broader legacy browser support while keeping strong compression. WebP is the safe fallback when AVIF is not yet universal.
How it works
When you need to go back to WebP
WebP and AVIF are both modern formats, so converting between them is a choice rather than a rescue. The common reasons are practical rather than technical: a content management system that will not accept AVIF uploads, an email client that renders the image wrong, a design tool that cannot read it, or a need for a format a particular platform validates. Each of those is a reason to keep a WebP copy, not to abandon AVIF entirely.
| Destination | AVIF accepted? | WebP accepted? | Safest choice |
|---|---|---|---|
| Your own website, modern browsers | Yes | Yes | AVIF with WebP fallback |
| Older browsers and webviews | No | Yes | WebP |
| Most email clients | Often no | Usually yes | JPG or PNG |
| Common CMS media libraries | Increasingly yes | Usually yes | WebP, check first |
| Design tools such as older suites | Rarely | Often | PNG or JPG |
| Print shops and lab upload forms | No | No | JPG or TIFF |
The quality cost of stepping back
As with any lossy conversion, moving from AVIF to WebP re-encodes an already compressed image. The file will come out larger than the AVIF it came from, because WebP is the less efficient of the two at the same quality. That is expected and is the price of the compatibility. One conversion is fine. Converting repeatedly in both directions is what damages an image, so keep whichever original has the most information.
- Expect the WebP output to be larger than the source AVIF. That is the format trade, not a failure.
- Convert once from your highest quality source, not from a previous conversion.
- Keep the original AVIF if you may need to re-export later.
- If size is the real goal and compatibility is not an issue, stay with AVIF.
Choosing a sensible quality setting
Because the output is larger than the input, the quality slider matters more than usual. Lowering it compensates for the format difference, but lowering it too far is where artefacts appear, usually as banding in skies and blockiness around edges. A balanced setting matched to the display size of the image is the sensible default, and checking the result at full size is the only reliable way to judge it.
- Start at balanced and compare against the original at 100 percent.
- Reduce the output size first if the image is far larger than where it will be displayed.
- Move up a step for images with gradients or fine text, where banding shows first.
- If the destination is email or print, use JPG or PNG instead rather than forcing WebP.

Frequently asked questions
Is WebP supported more widely than AVIF?
Yes. WebP has broader support in older browsers and operating systems, so it is safer for fallback.
Will converting AVIF to WebP lose quality
A small loss occurs because WebP recompresses lossy AVIF. Use balanced quality and keep the original AVIF as master. See WebP vs AVIF for comparison.
Should I serve WebP or AVIF on my site
Serve AVIF for smallest files and WebP as fallback for older browsers that do not support AVIF.
Will converting to WEBP degrade quality?
Every WEBP re-encode discards a little detail. Keep your original file if you might re-edit it later.
