Frequently Asked Questions

Is WebP supported everywhere?

Yes, in every current browser — Chrome, Edge, Firefox, Safari and all major mobile browsers. Support has been universal since Safari 14 in 2020. Some older desktop software still cannot open WebP files, so keep a JPEG copy for those workflows.

How much smaller is WebP than JPEG?

Typically 25–35% at equivalent visual quality, and sometimes more for images with large flat areas. The exact saving depends on the image, which is why the tool shows the real number for your file.

Does WebP support transparency?

Yes, unlike JPEG. That means WebP can replace both JPEG and PNG in most web use, which is why it is worth converting a whole image library.

Will converting improve my page speed score?

Smaller images reduce bytes transferred and usually improve Largest Contentful Paint. Serving correctly sized images and using lazy loading matter just as much, so treat conversion as one part of image optimisation.
