WP Enable WebP


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

Major features in WP Enable WebP include:

  • Enabling WebP Image uploads into the media library.
  • Browser detection that adds a class to the body tag indicating WebP is supported by the browser.
  • Helper function to use in theme template files to check if the browser supports WebP image format.


Upload the “wp-enable-webp” folder to your wp-content/plugins directory, then Activate it.

Really good plugin. I now use that plugin for nearly a year. It helps to save webspace. ItΒ΄s not updated for the newest WordPress version, but it still works without any problems or errors. Great work!
