Allow SVG through WordPress Media Uploader


For your functions.php file or a functionality plugin:

function cc_mime_types($mimes) {
  $mimes['svg'] = 'image/svg+xml';
  return $mimes;
add_filter('upload_mimes', 'cc_mime_types');

Without this, SVG files will be rejected when attempting to upload them through the media uploader.

Before WordPress 4.0, you also make them display properly in the Media grid. But that’s broken now. If anyone knows how to fix, let me know!

function fix_svg_thumb_display() {
  echo ' img[src$=".svg"], img[src$=".svg"].attachment-post-thumbnail { 
      width: 100% !important; 
      height: auto !important; 
add_action('admin_head', 'fix_svg_thumb_display');
