   Add MIME types.

   function my_custom_mime_types( $mimes ) {
   	
   	// New allowed mime types.
   	$mimes['svg']  = 'image/svg+xml';
   	$mimes['svgz'] = 'image/svg+xml';
   	$mimes['doc']  = 'application/msword'; 
       // Optional. Remove a mime type.
       unset( $mimes['exe'] );
   	return $mimes;
   }
   add_filter( 'upload_mimes', 'my_custom_mime_types' );

   • Allow SVGZ mime type:

      <?php function svgz_mime_types( $mimes ) {         // SVGZ allowed mime types.         $mimes['svgz'] = 'application/x-gzip';         return $mimes; } add_filter( 'upload_mimes', 'svgz_mime_types' ); ?>

   // To upload photos in format WebP
   
   function wpdocs_custom_mime_types( $mimes ) {
   	
   	// New allowed mime types.
   	$mimes['webp'] = 'image/webp';
   
   	return $mimes;
   }
   
   add_filter( 'upload_mimes', 'wpdocs_custom_mime_types' );

   If you work locally, for example on XAMPP, you should also include extension=gd in php.ini, just uncomment it, removing ; in front of it.
