Questions

Which browsers can open WebP and AVIF?

Current versions of Chrome, Edge, Firefox and Safari display both, but AVIF arrived later (Safari needs version 16 or newer, and older Edge builds lacked it). This page checks your own browser below.

Can I convert if my browser doesn’t support AVIF?

Yes. Encoding uses a WebAssembly build of libavif, independent of what your browser can display, and AVIF input falls back to a WebAssembly decoder.
