AVIF to WebP Converter: Free & Private
You need broader compatibility than AVIF without falling all the way back to JPG. Convert it here, in your browser, with nothing uploaded anywhere.
Why convert AVIF to WebP?
WebP is the sensible middle ground: it keeps transparency and modern compression, it is supported by essentially every browser and a good deal of software that still rejects AVIF, and it encodes fast. For a fallback image in a <picture> element, or a CMS that has not caught up to AVIF, this is the conversion you want. The two explainers, what AVIF is and what WebP is, set out where each one wins if you are deciding rather than converting.
The catch worth knowing about
Files will get bigger. WebP is roughly 20% behind AVIF at matched quality. That is the price of the compatibility you are buying.
One tip before you start
You do not have to choose. Serve AVIF first with the WebP as a fallback source, and every visitor gets the best format their browser supports.
