Frequently asked questions

Does WebP keep transparent backgrounds?

Yes. Like PNG, WebP supports an alpha channel, so transparent areas stay transparent.

Will every browser display WebP?

All current major browsers do. Very old software and some email clients may not, so keep a JPG copy for those.

How much smaller will the file be?

Often 25–50% smaller than PNG for the same picture, depending on the image and the quality chosen.
