ALLOWING SVG UPLOAD – using SVG files in WordPress

While direct insertion of .SVG code into the HTML block will work just fine, getting a .SVG file into the media library is a different thing. By default WordPress does not allow .SVG upload – mainly because the format being code based could contain malicious scripts.

This block of code in a theme’s function file would grant .SVG upload permission

//add SVG to allowed file uploads
function add_file_types_to_uploads($file_types){
    $new_filetypes = array();
    $new_filetypes['svg'] = 'image/svg+xml';
    $file_types = array_merge($file_types, $new_filetypes );
    return $file_types;
}
add_action('upload_mimes', 'add_file_types_to_uploads');

There are several plugins on the repository that achieve the same end here are the top two:

Safe SVG
SVG S upport

Both of these plugins will sanitize any uploaded .SVG file before allowing it into the media folder.
