How do you convert AVIF to WebP?
Upload your AVIFs
Drop the images in. Several are processed at once.
Re-encoding to WebP
The browser decodes the AVIF and re-encodes it as WebP at quality 90, alpha channel included.
Download the WebPs
Ready to upload to your website, an online shop or anywhere that does not accept AVIF.

Staying on the web without relying on AVIF
Converting AVIF to PNG or JPG fixes compatibility at the cost of a heavier file and, with JPG, of losing transparency. WebP is the middle ground: almost every current browser, CMS and editor accepts it, and it is still a compressed format built for serving images on the web.
It is the natural conversion when the image is going to be published again — on a shop, a blog or a social network — and the destination rejects AVIF.
The cost: a second compression
Both AVIF and this WebP output are lossy. Converting between them means decoding an already compressed image and compressing it again, and each step can add a little degradation.
That is why quality 90 is used — high enough that the difference does not show — and why it is best to convert once, from the original. If you need a copy with no additional loss at all, convert to PNG.
All in the browser
The AVIF is decoded and the WebP generated by the browser's own engine. Images are never uploaded to a server, and transparency comes through intact.

Frequently asked questions
Why go from AVIF to WebP if AVIF compresses better?
For compatibility. AVIF is newer, and there are still editors, content management systems, plugins and apps that reject it. WebP has been around longer and is far more widely supported, while still being a format designed for the web.
Will the WebP be larger?
Usually, yes. AVIF tends to compress better than WebP, so at similar quality the resulting file is normally somewhat bigger. It is still much lighter than a PNG.
Is quality lost?
A little. The WebP is lossy at quality 90, so it is a second compression on top of an image that was already compressed. At that quality the difference is rarely visible to the naked eye, but always start from the original AVIF rather than converting over and over.
Is transparency kept?
Yes. Both formats have an alpha channel, so cut-out backgrounds and soft edges carry over to the WebP intact.
Can I convert WebP to AVIF?
Not in the browser: browsers can read AVIF but cannot create it. That is why this conversion only goes one way.
