JPG to WebP

How to use it

1. Add your JPG photos.
2. Set the quality. Try 80% and compare it with the original.
3. Download the WebP versions.

Good to know

Re-compressing a JPG that is already heavily compressed gives little benefit and can add artefacts. Start from the highest-quality original you have.

Saving WebP requires Chrome, Edge or Firefox, because Safari does not offer this in the browser.

How much smaller will it be?

Google's published comparison found WebP about 25 to 34% smaller than JPG at equivalent quality. Your results depend on the picture and on how heavily the JPG was already compressed. Try 80%, then compare the two side by side at full size.

Avoid stacking compression

Every lossy save discards a little more. A JPG that already shows blocky areas will carry those flaws into the WebP, and the encoder wastes bytes on preserving them. Start from the largest original you have, and keep it as your master copy.

Using WebP on your site

• WordPress has accepted WebP uploads since version 5.8.
• Camera and location data are removed, which also shaves off a little size.
• Resize first. An oversized picture wastes more than the format can save.
• Saving WebP needs Chrome, Edge or Firefox.
