Adding visual elements to your site is an easy way to make your pages more engaging. You might include marketing banners, product images, galleries, or video tutorials. Unfortunately, including a bunch of files can weigh your site down and result in slower performance.
Lazy loading is a great way to relieve pressure on your server while increasing the loading speed of your website. It delays images from rendering for visitors until they’ve scrolled down to their place on the screen. Better yet, some lazy load plugins are free, easy to use, and come with extra features for website optimization.
In this post, we’ll explore some of the best lazy load plugins for WordPress. Then, we’ll show you how to choose the ideal tool for your needs.

Verdict: what’s the best lazy load plugin for WordPress?
The best lazy load plugin depends on your website needs. For instance, if you have many high-quality images on your site, you might prefer a plugin that offers image optimization features like compression and resizing.
Additionally, if most of your media files are videos or WebP formats, then it’s important to find a plugin with this capability since some tools will only work with JPEG/JPGs and PNGs.
With Jetpack Boost, you can tick multiple checkboxes. While you’re able to enjoy extra features like Critical CSS and deferral of non-essential JavaScript, Jetpack Boost isn’t going to weigh your site down with a bunch of tools you don’t need. Instead, these features are used to enhance quick content delivery along with lazy loading.
Better yet, you couldn’t ask for an easier tool to set up and configure. Once it’s installed on your site, simply head to the dashboard, where you’ll use toggles to enable/disable each of the settings. Then, Jetpack Boost works in the background of your site, requiring little to no ongoing maintenance.
How to choose a lazy load plugin
Now that you know the best lazy load plugins for WordPress, here are some ways to narrow down the right option for your site.
1. Make sure it matches your skill level
Some users might want a more hands-on tool with lots of control configurations and customization options. But for a beginner, all these settings can be intimidating. That’s why finding a lazy load plugin that matches your skill level is important.
If you don’t have a lot of tech experience, you’ll probably prefer a tool that’s easy to install and works automatically. There are plenty of options with “set and forget” options, so there’s no need to tinker around with complicated features and ongoing maintenance.
2. Check for additional features
If you’re looking for a lazy load plugin, you might simply want a method to delay the loading of images below the fold. Some of these plugins, like LazyLoad and Lazy Loader, do just what they say on the box.
But, for more complex, content-heavy websites, you can benefit from tools that provide additional features to enhance your content delivery. For instance, if you have a portfolio, you might want optimization and compression tools. Meanwhile, photography websites could find a watermarking feature useful.
3. Find out which image formats and sizes are supported
Typically, most plugins will accommodate popular image formats like JPEGs and PNGs. But not all tools offer lazy loading for animated images like GIFs or videos. Plus, some newer image formats like WebP and Retina might be ignored.
That’s why it’s important to ensure that the lazy load plugin you choose can support all the file types you intend to use on your website. Additionally, keep in mind that the free versions of some plugins are often a lot less powerful. Therefore, while a free lazy load plugin may seem like the best option in the short term, it might not work on large media files.
4. Make sure it’s compatible with other plugins on your website
The last thing you want to do is to get started with a lazy load plugin only to find that it isn’t compatible with other plugins essential to the running of your site. For example, if you own an online store, you probably rely on a platform like WooCommerce. Meanwhile, forum sites utilize specialized plugins like bbPress to gain functionality.
If the plugin isn’t compatible with other software you’ve installed, you risk breaking your site. Therefore, it’s crucial to pay close attention to the integrations and compatibility of your preferred tool. A good example of this is the Lazy Load for Videos plugin, which doesn’t work with a specific extension of Jetpack.
In general, Jetpack Boost, because it’s made by the people behind WordPress.com, will work reliably with most themes and plugins.
