It offers simple utility but suffers from reported fatal errors and a high price for Pro features.

You might not need this plugin. Its core job is small enough to live in your theme's functions.php.

Show the snippet

add_filter( 'upload_mimes', function( $mimes ) {
    $mimes['svg']  = 'image/svg+xml';
    $mimes['csv']  = 'text/csv';
    $mimes['xml']  = 'text/xml';
    $mimes['zip']  = 'application/zip';
    $mimes['ai']   = 'application/postscript';
    $mimes['mobi'] = 'application/x-mobipocket-ebook';
    $mimes['dwg']  = 'application/acad';
    // Add or remove entries as needed.
    return $mimes;
} );

// Required in WordPress 5.1+ to pass the real MIME check.
add_filter( 'wp_check_filetype_and_ext', function( $data, $file, $filename, $mimes ) {
    if ( ! $data['type'] ) {
        $ext = strtolower( pathinfo( $filename, PATHINFO_EXTENSION ) );
        $allowed = wp_get_mime_types();
        if ( isset( $allowed[ $ext ] ) ) {
            $data['ext']  = $ext;
            $data['type'] = $allowed[ $ext ];
        }
    }
    return $data;
}, 10, 4 );

Keep in mind:The snippet covers the core whitelist behaviour; the plugin also provides an admin UI for managing types without editing code.

Reviews

what people actually say

File Upload Types by WPForms is a generally well-regarded utility for expanding WordPress's allowed file types, praised for its ease of use and responsive support, but let down by recurring reports of custom file types failing to work and at least one serious PHP fatal error triggered by the plugin.

What people like

+Works reliably out of the box for most users needing to enable additional file types×5
+Custom file type drag-and-drop feature is effective and easy to use×2
+Support is praised as fast and helpful×3
+Clear instructions and clean UI

Common complaints

−Custom file type additions fail for some users, with uploads still being blocked despite correct MIME type configuration×3
−Fatal PHP error (Uncaught ValueError: Path cannot be empty) in Sanitizer.php caused site-wide critical errors affecting other plugins until disabled
−Some core functionality reportedly requires the paid Pro version, which is priced at $199/year
−Functionality is seen as something that should be built into WordPress or WPForms core rather than requiring a separate plugin
