How to Disable Scripts on Specific WordPress Pages

Most plugins load their CSS and JavaScript on every page of your site, even where they do nothing. A contact form plugin loads its files on your blog posts. A slider loads on pages without a slider. Each file is another request and more code for the browser to parse, and it adds up. The fix is to unload those files everywhere except the pages that need them.

Step 1: find the script and style handles

WordPress loads files through handles: names that plugins register with wp_enqueue_script() and wp_enqueue_style(). You need the handle to unload a file.

The quickest ways to find them:

• View the page source (Ctrl+U) and search for the plugin’s folder name. Stylesheets appear as <link id="contact-form-css" ...>: the handle is the id without -css. Scripts appear as <script id="contact-form-js" ...>: the handle is the id without -js.
• Install Query Monitor (free on WordPress.org). Its “Scripts” and “Styles” panels list every handle on the current page and which plugin added it.

Write down the handles and the pages where the plugin is really used.

Step 2: unload them where they aren’t needed

Hook into wp_enqueue_scripts with a late priority (so the plugin has already added its files), check which page you’re on, and dequeue:

add_action( 'wp_enqueue_scripts', function () {
    // Keep the form files only on the contact page.
    if ( is_page( 'contact' ) ) {
        return;
    }

    wp_dequeue_style( 'contact-form' );   // replace with your handles
    wp_dequeue_script( 'contact-form' );
}, 100 );

Useful WordPress conditions:

Condition	Matches
is_front_page()	the homepage
is_page( 'contact' )	a page by slug, ID or title
is_page( [ 'contact', 'quote' ] )	any of several pages
is_singular( 'post' )	single blog posts
is_archive()	category, tag and date archives
is_admin()	never use dequeue in wp-admin without checking this

Some plugins register extra files that depend on the main one. If something still loads, look for related handles in Query Monitor and dequeue them too.

Step 3: test

Open the pages where you removed the files and the pages where you kept them. Check the browser console (F12) for errors, and test the feature itself: submit the form, open the slider. If something breaks on a page, that page needs the files, so add it to the condition.

Make one change at a time and keep a list of what you unloaded. If a plugin update renames a handle, the file simply loads again; nothing breaks.

Where to put this code

You have three options:

• Your child theme’s functions.php. Works, but a typo can take the site down, and the code disappears if you switch themes.
• A code snippets plugin. Keeps snippets separate from the theme, with an on/off switch for each.
• Scripts Organizer. Add the snippet as a PHP code block with the Everywhere trigger location. You get a full code editor, can switch any snippet on or off with a toggle, and have a safe mode in case a snippet breaks something.

The same approach works for your own CSS and JavaScript. Scripts Organizer can load a code block only on selected pages, post types or taxonomy archives (the Template conditions), exclude specific pages from “everywhere”, or schedule it by date and time, so your custom code is also only loaded where it’s needed.
