Frequently asked questions

How much smaller can WebP get?

Lowering quality to 70–80% typically cuts WebP size by 30–60% with minimal visible loss.

Does WebP compression keep transparency?

Yes. WebP supports alpha transparency, which is preserved during re-encoding.

Can I compress animated WebP?

Only the first frame is kept, because the canvas pipeline renders still images. Use a dedicated tool for animated WebP optimization.
