This WordPress Plugin for WebP image uploads enabled WebP image uploads into the media library.

It will also add a class to the body tag for CSS selectors. This is helpful for setting background images.


selector {

background: url(‘images/example.jpg’);

body.supports-webp #selector {
background: url(‘images/example.webp’);

Use the function webpSupported() in template files to conditionally show WebP images.

if (webpSupported()) :
WebP image here
Image with other fallback format here
