How much does WEBP actually save?

On photographs, usually a quarter to a third of the bytes at the same visible quality. On line art and flat colour the win can be larger; on already-aggressively-compressed JPGs, smaller.

Do all browsers support WEBP?

Every current mainstream browser does, including Safari on macOS and iOS. If you must serve a very old client, keep the JPG alongside and use a source-set fallback.

Will I need to re-do this for AVIF?

AVIF usually shaves a little more, but converts are one-way here: you can turn AVIF into JPG or PNG today, which is the honest migration path.
