Smaller again, but slower to encode and less universally supported. WebP is the safer default today.

≈25–30% smaller than JPEG

WebP produces files roughly 25–30% smaller than JPEG at matching visual quality, and it supports transparency like PNG. Every current browser reads it, which removes the main reason people used to avoid it.

How to compress to WebP

1 Drop in images of any format your browser can read.

2 Set the quality — 78 is a good default.

3 Cap the longest side if the images are oversized.

4 Download the batch as a ZIP.

WebP replaces both JPEG and PNG for web use, which is the unusual thing about it: lossy mode competes with JPEG on photographs while lossless mode with alpha competes with PNG on graphics. The remaining friction is outside the browser — some desktop software, older email clients and a few social platforms still handle it poorly, so it is the right format for a website and occasionally the wrong one for a file you are sending to someone.
