WebP produces files roughly a quarter to a third smaller than JPG at the same visual quality, which is why page-speed audits keep recommending it. Converting a site's JPG photos to WebP is one of the cheapest performance gains there is: pages load faster, mobile visitors use less data, and Core Web Vitals improve without changing a single pixel of layout. Every current browser displays WebP.
Typically 25–35% at matched visual quality. Heavily detailed photos save a little less, smooth images such as skies and portraits a little more.
Yes: Chrome, Edge, Firefox and Safari 14 and later all display it. The remaining concern is older desktop software and some email clients, which is why WebP is best for websites rather than attachments.
Displaying WebP and creating it are separate features. Safari shows WebP but its canvas cannot write it, so the conversion needs Chrome, Edge or Firefox: on any operating system, including macOS.
No. The browser WebP encoder is lossy at every quality level; 100 is simply the least compression. For a lossless master keep PNG.
No. Converting through the canvas writes pixels only, so camera details and GPS coordinates are stripped, usually desirable for images you publish.

Add JPG photos
Drop the images you serve on your site. PNG, BMP and TIFF are accepted too.
- 2
Set the quality
Around 80 is the usual web setting: visibly identical to the JPG and much smaller.
- 3
Resize for the layout
Enter the widest size the image is actually displayed at. Serving a 4000 px photo in a 1200 px slot wastes more than any format change saves.

- ·Keep the original JPGs: WebP is for delivery, not archiving
- ·Use a <picture> element with a JPG fallback if you still support very old browsers
- ·Resizing to the displayed width usually saves more than the format switch itself
