Practical format guide
Browser support for WebP to AVIF conversion
AVIF encoding from a browser canvas is not available in every browser engine. This tool uses native browser encoding when the capability is present and reports a clear error when it is not.
Use a current browser
For the best chance of AVIF export support, use a current Chromium-based browser. Decoding WebP is broadly supported.
Choose quality carefully
AVIF can be very efficient. Start around 82% and compare the result with the original WebP.
Resize oversized images first
Reducing unnecessary pixel dimensions can improve file size regardless of the final image codec.
