Frequently asked questions

Does WebP keep PNG transparency?

Yes. WebP supports an alpha channel, so transparent logos and icons stay transparent after conversion.

How much smaller is WebP than PNG?

It depends on the image. Photos saved as PNG often shrink by 70% or more, while simple flat graphics shrink less. The tool shows the size before and after for every file.

Do all browsers support WebP images?

Yes, every current version of Chrome, Edge, Firefox and Safari shows WebP images, so it's a safe format for websites today.
