Convert WebP to AVIF
Updated Jul 2026
WebP is the image format most modern websites already use, and AVIF is a newer format that can hold the same picture in a noticeably smaller file. To convert, open the WebP in a converter and export it as AVIF. Doing that on your own computer means the image never has to be sent anywhere to be converted.

How to convert WebP to AVIF
- Open Morphjet and drag in the WebP images you want to convert. Add one file or a whole folder at once.
- Choose AVIF as the output format, and set a quality level if you want to trade some detail for a smaller file.
- Convert. The AVIF files are written next to your originals, and nothing leaves your machine.
WebP vs AVIF: what actually changes
| WebP | AVIF | |
|---|---|---|
| Opens everywhere | Yes, supported by nearly all current browsers and apps | Growing, but some older browsers, editors, and CMS tools still can't open it |
| File size | Compact | Often noticeably smaller at the same visual quality |
| Quality | Very good, lossy compression with a wide quality range | Very good, and tends to hold detail better at low file sizes |
| Transparency | Yes | Yes |
| Opens in image editors | Widely supported | Support is improving but still patchy in older software |
When to convert, and when not to
Convert WebP to AVIF when you want to shrink website images further to speed up page loads, and you're fine with a format that newer browsers handle well but some older tools don't.
Keep the WebP if the images need to open reliably in older browsers, image editors, or a CMS that hasn't added AVIF support yet, since WebP compatibility is still noticeably wider.
Why not just use an online converter?
Plenty of free WebP to AVIF converters work by having you upload your image to their server, convert it there, and send it back. That's an extra copy of your photo, screenshot, or product image sitting on a computer you don't control. Converting on your own machine skips that step entirely, the file goes from WebP to AVIF without ever leaving your hard drive.
Questions
Does converting WebP to AVIF lose quality?
Both are lossy formats, so there's some re-compression on export, but at a matched quality setting AVIF usually keeps as much or more visible detail than WebP while producing a smaller file.
Will the AVIF file work everywhere the WebP did?
Not necessarily. Current browsers handle AVIF well, but some older browsers, image editors, and content platforms still don't open it, so check where the image needs to work before converting.
Why convert to AVIF instead of just keeping WebP?
Mainly for smaller file sizes. If you're serving a lot of images and want faster page loads, AVIF's tighter compression can add up, as long as your audience's browsers support it.
Does the AVIF keep the transparency from the WebP?
Yes. AVIF supports transparency just like WebP, so a WebP image with a transparent background will convert cleanly to AVIF without adding a background color.
Can I convert WebP to AVIF without uploading it anywhere?
Yes. A desktop app like Morphjet converts the file locally on your own computer, so the image never travels over the internet, you could even do it with your wifi off.
