How much smaller are WebP files compared to JPEG and PNG?

WebP lossy images are typically 25–34% smaller than JPEG at equivalent quality. WebP lossless is around 26% smaller than PNG. For a site with many images, this translates to significant bandwidth savings.

Is WebP supported in all browsers?

Yes. WebP is supported in Chrome, Firefox, Safari (since version 14), Edge, and Opera — covering over 95% of global browser usage. For the remaining browsers, serve JPEG as a fallback using the HTML picture element.

Does converting to WebP affect image quality?

At quality settings of 80+, WebP images are visually indistinguishable from the original JPEG or PNG to most viewers. Lower quality settings produce more visible artifacts but dramatically smaller files.
