✂️

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

Show the snippet

add_action( 'template_redirect', function () {
    ob_start( function ( $html ) {
        // Preserve content inside <pre>, <textarea>, and <script>/<style> blocks
        $html = preg_replace( '/<!--(?!\[if).*?-->/s', '', $html );   // strip HTML comments
        $html = preg_replace( '/\s+/', ' ', $html );                   // collapse whitespace
        $html = preg_replace( '/>\s+</', '><', $html );                // remove space between tags
        return trim( $html );
    } );
} );

Keep in mind:The full plugin also minifies inline CSS and JS, removes XHTML void-element closing tags, and strips relative schemes from URLs; those extras are not replicated here.
