How to Easily Lazy Load Images in WordPress (2 Ways)


In the fast-paced world of website optimization, lazy loading images has become a crucial technique to enhance user experience and improve website performance. If you’re a WordPress user looking to boost your site’s loading speed and reduce its bandwidth usage, then you’re in the right place.

In this blog post, we’ll explore two easy methods to implement lazy loading for images in your WordPress website. By the end of this guide, you’ll be well-equipped to reduce page load times and create a smoother browsing experience for your visitors.

What is Lazy Loading?

Before diving into the methods, let’s quickly recap what lazy loading is and why it’s important.

Lazy loading is a technique that delays the loading of non-visible images on a webpage until the user scrolls down and the images are about to come into the viewport. This results in faster initial page load times because only the images visible in the user’s browser window are loaded immediately. The rest are loaded as the user scrolls, reducing the overall page size and improving performance.

Method 1: Using a Plugin

WordPress offers a multitude of plugins to simplify tasks, and lazy loading images is no exception. Here’s how you can easily implement it using the “Lazy Load by WP Rocket” plugin:

  1. Install and Activate the Plugin: In your WordPress dashboard, navigate to the “Plugins” section and search for “Lazy Load by WP Rocket.” Install and activate the plugin.
  2. Configure the Plugin: After activation, go to the plugin settings. You can customize various options, such as enabling or disabling lazy loading for iframes and videos, and tweaking the threshold for when images load. Configure these settings according to your preferences.
  3. Save Changes: Once you’ve configured the plugin settings, don’t forget to save changes. Your WordPress site will now automatically lazy load images.

Method 2: Manual Implementation

If you prefer to have more control over your website’s functionality, you can implement lazy loading manually without relying on a plugin. Here’s how:

  1. Edit Your Theme’s Functions.php File: In your WordPress dashboard, navigate to “Appearance” and then “Theme Editor.” Find the “functions.php” file of your active theme and open it for editing.
  2. Add Lazy Loading Code: To manually add lazy loading, you can use a simple HTML attribute called “loading” on your image tags. Locate the image tags in your theme’s templates and add the “loading” attribute with the value “lazy.”


                        <img src="image.jpg" alt="Description" loading="lazy">
  3. Save Changes: Save the changes to your functions.php file.
  4. Test Your Website: To ensure that lazy loading is working correctly, visit your website and scroll through some pages. You should notice that images load as you scroll down the page.


Lazy loading images in WordPress is an effective way to improve website performance and enhance user experience. Whether you choose to use a plugin like “Lazy Load by WP Rocket” or implement it manually, your visitors will appreciate the faster load times and smoother browsing experience. Take action today and optimize your WordPress site with lazy loading – your users and your website’s performance will thank you!
