Frequently asked questions
How's WebP support?
Modern browsers (Chrome / Firefox / Safari / Edge) support WebP, covering 96%+ of users — it's the go-to web image format.
Why does quality do nothing for PNG?
PNG is lossless, so the quality slider doesn't apply. To shrink it meaningfully, switch to WebP or JPG, or cap the max width.
