AVIF searches much harder for ways to save bytes, and that takes time. A big photo can take many seconds even on a fast laptop.

Can everyone view AVIF?

All current major browsers can. For very old browsers, serve a JPG or WebP fallback.

Is a quality of 60 too low?

AVIF's scale isn't JPG's. Quality 60 in AVIF is usually comparable to around 80 in JPG.

No. Encoding happens in your browser with WebAssembly, so nothing is sent to a server.
