AVIF→WEBP

Convert AVIF to WEBP

Turn an .avif image into a WEBP — right in your browser, with a real re-encode via canvas, not a server upload. Keeps transparency, and WEBP support is broader than AVIF across older tools and CDNs.

Convert a AVIF File to WEBP

Drop an .avif file below. Your browser decodes it (AVIF is supported by all current major browsers), then it's re-encoded as a real WEBP on a canvas — transparency preserved — previewed here, ready to download.

Why convert AVIF to WEBP

AVIF is the newest and most efficient of the modern web image formats, but WEBP has been around longer and is supported by a wider range of image CDNs, editing tools, and older browser versions. Converting AVIF to WEBP is a common middle ground when a workflow doesn't (yet) fully support AVIF, without falling back all the way to JPG or PNG.

Edge cases this tool handles

Animated or HDR AVIF

Only the first frame is converted, and your browser tone-maps any HDR/wide-gamut color down to standard sRGB for the WEBP, the same way it would display the image on a standard screen.

Transparent AVIF

Fully preserved — WEBP supports an alpha channel, so transparent and semi-transparent areas from the source AVIF carry over.

File size

AVIF is generally the more efficient format, so the output WEBP will often be somewhat larger than the source AVIF at a comparable visual quality — the tradeoff for WEBP's broader compatibility.

Frequently asked questions

Does converting AVIF to WEBP upload my file anywhere?

No. The image is decoded and re-encoded entirely inside your browser using a canvas — the file never leaves your device or touches a server.

Do I need a special browser for this to work?

No — all current versions of Chrome, Firefox, Edge and Safari can decode AVIF natively. Only a very old browser version might not support it.

Does converting to WEBP keep transparency?

Yes — WEBP supports an alpha channel, so transparent and semi-transparent pixels in the source AVIF are preserved in the output.

Why convert to WEBP instead of just keeping AVIF?

WEBP has broader support across older browsers, image CDNs, and editing tools that don't yet handle AVIF — converting is a practical middle ground when your workflow needs that wider compatibility.
