Common questions

Is WebP supported everywhere?

All current major browsers support it. Very old clients may not, so keep a fallback if that matters.

Does WebP support transparency?

Yes. It handles alpha well, which makes it a good replacement for PNG graphics.

Will conversion lose quality?

It is lossy at most quality settings. Compare at 100% zoom before replacing the original.
