   Here’s a quick one-liner using this filter that I wrote for a site that serves .webp images as well as whatever jpeg or png was uploaded to WordPress. When any image file is deleted, it also deletes the .webp version, if it exists. e.g. when you delete an image such as /uploads/2024/01/example.png from the Media Library, it will also delete /uploads/2024/01/example.webp.

   /* When image files are deleted, also delete the .webp version, when it exists */
   add_filter( 'wp_delete_file', function ( string $file ): string {
     return preg_replace_callback( '/^(.+\.)(?:bmp|gif|jpe?g|pdf|png)$/i', function ( array $matches ): string {
       wp_delete_file( $matches[1] . 'webp' );
       return $matches[0];
     }, $file );
   } );
