How do I convert AVIF to WebP?

Drop the file on this page. It runs in your browser, so there is no upload, no account and no daily limit.

Why will my software not open a AVIF file?

Desktop editors, operating system previews, and most software written before about 2022 that opens images as a side job.

Why WebP specifically?

WebP keeps transparency at a fraction of the size, as long as whatever opens it is a browser. Outside one it is still the format people ask about.

Is the image uploaded?

No. It is decoded and re-encoded by the page, and no request carries it anywhere, which the network panel will show you.
