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.
Example:
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.
Example: 
if (webpSupported()) : 
 WebP image here 
 else: 
 Image with other fallback format here 
 endif;
Major features in WP Enable WebP include:
<ul>
<li>Enabling WebP Image uploads into the media library. </li>
<li>Browser detection that adds a class to the body tag indicating WebP is supported by the browser.</li>
<li>Helper function to use in theme template files to check if the browser supports WebP image format.</li>
</ul>

WP Enable WebP

Works fine for uploading webp images. I set one up as a featured image, it loads fine on a desktop, but for mobile users also loads a full-size image. Does not scale it down like jpeg formats...

Would be great if the developer could continue his work on it.
