/**
 * Remove Contact Form 7's scripts and styles without having to add anything to wp-config.php (as described
 * in the CF7 docs) by using the wpcf7_enqueue_styles and wpcf7_enqueue_scripts actions that Takayuki was
 * nice enough to include in includes/controller.php
 * @link http://contactform7.com/loading-javascript-and-stylesheet-only-when-it-is-necessary/
 */
add_action( 'wpcf7_enqueue_styles', function() { wp_deregister_style( 'contact-form-7' ); } );
add_action( 'wpcf7_enqueue_scripts', function() { wp_deregister_script( 'jquery-form' ); } );

Working good ! Thank you. For adopters you might consider using conditions on page.

I see this was written 7 years ago, does it still work? I need to deregister scripts then put them in my theme scripts.js file. Odd because @Dinath commented recently that it works, but I don't see a jquery-form.js script anywhere in the plugin folder

I can confirm that deregistering the styles works, but deregistering the script doesn't work. What does work is this:

Add this to the theme's functions.php file
add_filter( 'wpcf7_load_js', '__return_false' ); add_filter( 'wpcf7_load_css', '__return_false' );

Add this to the theme header.php, just above <?php get_header(); ?>

<?php
if (is_page('the_page_i_want_to_show_the_scripts_and_styles')) { 
    if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {
        wpcf7_enqueue_scripts();
    }
  
    if ( function_exists( 'wpcf7_enqueue_styles' ) ) {
        wpcf7_enqueue_styles();
    }
}
?>

Replace 'the_page_i_want_to_show_the_scripts_and_styles' with the page slug.
