Convert AVIF to WebP online

AVIF compresses beautifully but still trips up a lot of software: older browsers, many CMS media libraries, email clients and image editors. Converting AVIF to WebP gives you near-identical file sizes with support virtually everywhere.

Why convert AVIF to WebP?

Compatibility. WebP works in 97%+ of browsers and every mainstream CMS, plugin and image editor.

Tiny size penalty. WebP files are usually only 10–20% larger than AVIF at matching quality.

Faster to encode and decode, which matters for image-heavy pages on low-end devices.

Upload anywhere. Many platforms (WordPress before 6.5, older Shopify themes, email tools) reject AVIF but accept WebP.

How to convert AVIF to WebP

Step 1

Select your AVIF files

Click the drop zone or drag and drop your AVIF images. Files stay on your device; nothing is uploaded.

Step 2

Choose quality and size

Move the quality slider (80% is ideal for most images) and set a maximum width to downscale oversized images.

Step 3

Convert to WebP

Press "Convert to WebP". Your browser encodes each AVIF to WebP in a fraction of a second.

Step 4

Download

Download each WebP file, or grab the whole batch as a ZIP with PRO.

When does AVIF to WebP make sense?

AVIF is technically excellent, and if you can serve it with a WebP fallback via the <picture> element, do so. But you often cannot: a client's CMS refuses the upload, a newsletter tool renders a broken image, or a stock photo download arrives as AVIF and your designer's software cannot open it. In those cases, WebP is the format that just works.

Quality settings for AVIF sources

AVIF files are already lossy, so avoid stacking too much extra compression. Use 82–90% to stay visually transparent to the AVIF source. Expect the WebP to be roughly the same size, sometimes slightly larger; the trade is compatibility, not size.

AVIF to WebP: questions

AVIF compresses 10–20% better at equal quality, but WebP is faster, more widely supported and accepted by far more software. For most websites the practical difference is negligible.

Your browser probably cannot decode AVIF. Update to a current version of Chrome, Firefox, Edge or Safari 16.4+ and try again.
