Do you want to replace the default WordPress jQuery script with jQuery from Google Hosted Libraries?

WordPress includes jQuery with the core software by default. However, replacing it with the latest jQuery version from Google library can improve performance.

In this article, we’ll show you how to easily replace the default WordPress jQuery script with Google library to improve performance and speed.

Replacing the WordPress jQuery with Google library

Why & When You Should Replace Default WordPress jQuery

jQuery is a popular JavaScript library used by developers to create beautiful web applications. It’s used quite often in WordPress to add features like sliders, popups, and much more.

WordPress includes a jQuery library packaged with the core WordPress software. Many of the top WordPress plugins and most popular WordPress themes rely on this library for essential functionality and features.

JQuery and other third-party scripts packaged in WordPress

However, loading jQuery on a shared hosting server can be resource-intensive and slow down your site, especially if you are using any poorly coded WordPress themes or plugins that don’t follow WordPress best practices.

Another issue with using the jQuery version that’s included with WordPress is that it won’t get updated unless WordPress updates it. There could be newer versions of jQuery with performance or security fixes, but you won’t get access to them until they’re included in a WordPress update.

There are a few workarounds to fix this. For instance, you can load jQuery via Google servers or jQuery’s official CDN.

Google Hosted Libraries is a good choice because their servers are stable, updated, and highly optimized for speed which allows jQuery to load much faster on your WordPress site.

That being said, let’s take a look at how to easily replace the default WordPress jQuery with the Google library.

Replace Default WordPress jQuery with Google Library

WordPress comes with a built-in method to easily add scripts and stylesheets. This also allows you to safely remove any scripts or stylesheets that are loaded using the built-in method.

We’ll use this method to first disable the WordPress default jQuery. After that, we’ll tell WordPress to load jQuery via Google library.

You’ll need to add the following code to your theme’s functions.php file, a site-specific plugin, or a code snippets plugin.

function wpb_modify_jquery() {
    //check if front-end is being viewed
    if (!is_admin()) {
        // Remove default WordPress jQuery
        // Register new jQuery script via Google Library    
        wp_register_script('jquery', '', false, '3.6.0');
        // Enqueue the script   
// Execute the action when WordPress is initialized
add_action('init', 'wpb_modify_jquery');

We recommend using the WPCode code snippets plugin to add this code in WordPress. It’s free, easy to use, and won’t break your website if anything goes wrong.

Note: There’s also a premium version of WPCode that offers advanced features like code revisions, automatic conversion pixels, scheduled snippets, a private cloud library, and more.

To get started, you’ll need to install and activate WPCode. If you need help, see our guide on how to install a WordPress plugin.

Once the plugin is activated, navigate to Code Snippets » Add Snippet from your WordPress dashboard. From there, find the ‘Add Your Custom Code (New Snippet)’ option and click the ‘Use snippet’ button underneath it.

Add a new custom code snippet in WPCode

Next, you can add a title for your code snippet. This can be anything to help you remember what the code is for.

After that, simply paste the code from above into the ‘Code Preview’ box and select ‘PHP Snippet’ as the code type from the dropdown menu.

Paste code snippet into WPCode

Lastly, toggle the switch from ‘Inactive’ to ‘Active’ and click on the ‘Save Snippet’ button.

Activate and save your custom code snippet

That’s all! WordPress will now replace the default jQuery and load it via Google library instead.

Note: This method will continue loading the jQuery version mentioned in the URL. In the future, you may need to change the Google library URL to use a newer jQuery version.

Google won’t automatically update the version number for you because it could cause compatibility issues if your theme or plugins are relying on a different version.

You can find the latest URL by visiting the Google hosted libraries website.

Google hosted libraries - jQuery

From there, you can also find the URLs for older versions of jQuery that you can use for troubleshooting if needed.

Replacing Other Default jQuery Libraries

Apart from the core jQuery library, WordPress also includes a bunch of other jQuery scripts. Some of these scripts, like jQuery Mobile and jQuery UI, are hosted on Google library.

For other libraries, you can use jQuery’s own CDN servers to load them much quicker. In the following example, we have replaced the WordPress jquery-ui-core script with the official jquery-ui version.

function wpb_modify_jquery_ui() {
if (!is_admin()) {
wp_register_script('jquery-ui-core', '', false, '1.12.1');
add_action('init', 'wpb_modify_jquery_ui');

Just like Google libraries, you will need to replace the URL after a while to use the latest version of the script.

Completely Disable jQuery in WordPress

Due to its wide usage, we don’t recommend completely disabling jQuery on your WordPress website. Even if your WordPress theme doesn’t use jQuery, many popular WordPress plugins still need it.

However, if you’re certain that your website doesn’t need jQuery, then you can safely disable it.

Simply add the following code to your theme’s functions file, a site-specific plugin, or a code snippets plugin like WPCode.

if ( !is_admin() ) wp_deregister_script('jquery');

That’s all. This code simply disables the jQuery script from loading on the front end of your WordPress website.

Troubleshooting jQuery Related Issues in WordPress

New versions of jQuery can sometimes deprecate, or remove, old methods and functions. If a WordPress plugin on your website is using an older method, then this could potentially break things.

You may notice warnings in the Console area of the Inspect tool, or you may notice some features have just stopped working.

WordPress used to use a script called jQuery-migrate to provide backup compatibility with older versions of jQuery. However, since WordPress 5.5 this script has been retired from WordPress.

If you want to add back the jQuery-migrate script or troubleshoot between different jQuery versions, then you can try the following method.

Simply install and activate the Version Control for jQuery plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to visit the Settings » jQuery Version Control page. From here, you can choose the jQuery version you want to use.

The plugin will automatically load that version from the official jQuery CDN.

jQuery version control

The plugin will also load the jQuery migrate script. If you want, then you can disable it during troubleshooting.

Don’t forget to click on the ‘Save Changes’ button to save your changes.

    We have a server in China, and all of resource from Google are blocked by Chinese government firewall.

    But, the Jquery and Fonts resources are loaded from Google on WordPress by default now, and the site is caused seriously delay.

    So, is there anyway to force Js or CSS resources to be loaded from local server please?


    • WPBeginner Support says

      If you have a web address for the jquery files on a local server then you would change the url in the snippet to point toward where the jquery is located.

    Hey, sorry for haling this post out of the grave… :) How relevant is this still? In Terms of the latest P Core versions?

    Here is a more advanced implementation:

    add_action( ‘wp_enqueue_scripts’, ‘register_jquery’ );
    function register_jquery() {
    if (!is_admin()) {
    wp_register_script(‘jquery-core’, ‘’, true, ‘1.11.3’);
    wp_register_script(‘jquery-migrate’, ‘’, true, ‘1.2.1’);

    Where “” it should be replaced by the file path, using a CDN for a better result.

    Best Regards,

    Jorge Ortiz

        Jorge’s code worked for me – but the quotation marks must be replaced. Try this:

        add_action( ‘wp_enqueue_scripts’, ‘register_jquery’ );
        function register_jquery() {
        if (!is_admin()) {
        wp_register_script(‘jquery-core’, ‘’, true, ‘1.11.3’);
        wp_register_script(‘jquery-migrate’, ‘’, true, ‘1.2.1’);

        • Plato39 says

          OK – it’s this webpage that is adding the fancy quotes. Just do a ‘find and replace’ in your text editor (or manually replace the quotes with plain ones) and the code will work in your theme’s functions.php file.

    thank you very much for your post, I tried to change it and do not know if I did well because my web now is 2 seconds slower
    How do I check if I did well and I’m using the google libraries?

  6. Ihsan says

    I tested code above and i replace the last line with this to make it work and better

    add_action( ‘wp_print_scripts’, ‘modify_jquery’, 100 );

  7. Alejandro says

    Hi, Thank you for your tips. I do not know Why when using this function, the jquery from Google is loading twice, I mean, I have two HTTP request instead of one, Here is the test:!/dROQaF/

    With jquery.easing the same happends, but this time with 3 HTTP request for the same file.

    Any ideas? I’ve been looking into the code but didn’t find duplication of wp_enqueue_script(”);

    Thank you in advance

  8. Joseph Chambers says

    What if I want to load either HTTP or HTTPS based on whatever the visitor is visiting our page on.

    for most things we can change: -> // and it works. However; something in the wp_register_script() is throwing a error ( White page with the word: Error ) when I change that. thoughts, solutions?

    Here is the latest version of the googleapi jquery file.

    When you copy/paste the code above, don’t forget to replace the jquery URl by this one :

    Then replace “1.4.4” by “1.6.2”

    Like that :

    //Making jQuery Google APIfunction modify_jquery() { if (!is_admin()) { // comment out the next two lines to load the local copy of jQuery wp_deregister_script(‘jquery’); wp_register_script(‘jquery’, ‘’, false, ‘1.6.2’); wp_enqueue_script(‘jquery’); }}add_action(‘init’, ‘modify_jquery’);

    • vnu says

      Could anyone tell me if I need to modify (!is_admin) to “minimum” capability if I use a plugin plugin like thethefly ‘s tabs and accordions . So the tabs created on pages are view-able by everyone?

      Thanks !

  10. Melissa Cleaver says

    Thanks so much for the code, but when I tried to use it in my functions.php file, I got a fatal error, no matter where in the code I put it. Am I doing something wrong here?

    Question: does Google Library do a good job at pulling in the alt tag info from the media library? … I have several professional themes that use a main page jQuery slider, but they don’t pull in the alt tag … thus, the source code look like: alt=”” … which of course, is an seo no-no. I’ve never used the Google Library script … I’d be curious how that works. What’s your experience?

      • swanie says

        OK … I guess I’m specifically talking about jQuery sliders … I have purchased several professional themes with a main page jQuery slider … here’s one of them: … if you view source, it pulls in the images, but not the alt tags … the alt tag is empty.

        I guess by reading this post, this Google Library approach could possibly resolve that.

        Another solution could be to break open the plugin files and add to the alt tag so I should have:

        img src=”file.jpg” alt=”” title=””

        Just wondering why these jQuery sliders don’t pull in the alt tags. That make sense? Am I off-subject?

        You guys rock, by the way.
