There are numerous ways of further developing your WordPress site’s exhibition. Best lazy Loading WordPress Plugin 2022 Pictures and different media records are probably the greatest guilty parties behind long stacking times. That implies executing any picture improvement strategies can essentially affect site execution, and sluggish stacking is no special case.

In this article, we’ll discuss how languid stacking works and how it can help your site. Then, at that point, we’ll show you probably the most well-known ways of adding postponed stacking in WordPress for a considerable length of time of components. At last, we’ll discuss the absolute most normal specialized issues this setting may cause.

What Is Lazy Loading?

As a rule, when you visit a site, every one of its parts attempts to stack immediately. Your program will show each medium resource, text, interface, and another component on the page. Assuming the page has numerous media resources, for example, pictures, they can dial back stacking times significantly.

There are a lot of ways of decreasing the effect that pictures have on page stacking times. You can enhance pictures, empower program storing, utilize a Content Delivery Network (CDN), and pick more modest document types. In a perfect world, you’ll exceed everyone’s expectations and carry out whatever number of those improvements as could be allowed since there’s no such thing as a site that is excessively quick.

Lethargic stacking doesn’t diminish picture document sizes or change what amount of time they require to stack for every client. Conversely, this setting can concede stacking each image until your program viewport arrives at the part of the page with that record:

In practice, deferred loading should have a minimal impact on how users interact with your website if you already have a responsive site. Most visitors shouldn’t notice images appearing as they scroll through your pages. At the same time, you can benefit from faster initial loading times since users won’t have to request and load every image simultaneously.

What Are the Benefits of Lazy Loading in WordPress?

Delayed loading can help initial loading times. This is essential when you consider that 40 percent of users will leave a webpage if it takes more than three seconds to load. Therefore, this setting can entice visitors to stay on your site and browse your content.

Furthermore, delayed loading can reduce the strain on memory and storage. As such, using it might enable you to opt for a more affordable website hosting plan.

It’s important to note that as of WordPress 5.5, the Content Management System (CMS) lazy loads images by default. However, there’s some contention about whether the default approach can harm Core Web Vitals scores.

By default, the delayed loading improves loading times on paper. However, it can also hurt Largest Contentful Paint (LCP) scores.

LCP measures how long it takes for the largest image or text block on any page to load:


WordPress uses the HTML loading=lazy attribute for images on your website. Generally speaking, that is the easiest way to implement deferred loading. However, not all browsers support that attribute.

If you want to disable deferred loading for specific images, you’ll need to modify that attribute manually using HTML. The alternative is using a WordPress plugin that implements delayed loading with a different approach (which gives you more control).

Can Other Elements Have Lazy Loading?

Actually talking, you can concede stacking for practically any component on a site. Postponed stacking functions admirably with pictures, and it’s likewise an amazing component for video resources.

Beside media resources, you can likewise concede stacking code like JavaScript and CSS. Indeed, we suggest postponing scripts that might hinder delivering on your site to further develop your First Contentful Paint (FCP) scores.

Continuing on, you can likewise decide to sluggish burden text resources. Notwithstanding, that is not a decent practice from an ease of use outlook. Besides, regardless of whether you show a whole book of text on a page, it shouldn’t essentially affect stacking times.

Conceded stacking is best for weighty media resources that fundamentally sway stacking times. Be that as it may, WordPress center just backings languid stacking for pictures. To stretch out that training to different components, you’ll have to search for an elective execution. That is the place where modules come in.

How to Add Lazy Loading for Images and Video in WordPress

As we mentioned before, WordPress adds lazy loading for all images by default. However, you’ll have little control over which pictures to lazy load. If you want to opt for a different approach, we recommend using the a3 Lazy Load plugin.

Step 1: Install and Activate the a3 Lazy Load Plugin

The a3 plugin enables you to exclude specific images and pages from lazy loading. Moreover, it also supports delayed loading for videos on your website:

This plugin also adds support for lazy loading external images and videos. That is something that the WordPress core implementation doesn’t do.

Install and activate the plugin from your WordPress dashboard. You’ll now be able to customize the tool’s settings.

Step 2: Adjust the Plugin Image Settings

Next, head to Settings > a3 Lazy Load. Looking under Lazy Load Activation, you’ll notice that the plugin is turned on by default after installation.

Open the Lazy Load Images tab. You can (1) choose which images to delay within your website and (2) enable a fallback for browsers that block JavaScript. You can also (3) set a CSS class for images that you don’t want to defer loading for:


The default settings have every option turned on, which we recommend maintaining. Go ahead and set up a CSS class that will enable you to skip deferred loading for specific images.

Step 3: Adjust the Plugin Video Settings

Next, move on to the Lazy Load Videos and iframes tab. Just as with images, a3 Lazy Load enables you to choose delayed loading for specific clips.

The plugin supports videos in (1) content and widgets, and it offers (2) a fallback feature for browsers that block JavaScript:

The video settings (3) enable you to specify a CSS class that excludes specific videos from deferred loading. For easier configuration, you can use the same class you chose in the images section.

Step 4: Disable Delayed Loading (Optional)

Finally, if you want to disable deferred loading for specific types of pages, you can do so in the Exclude by URLs and Page Types tab. Here you can enter particular pages or content types that shouldn’t use lazy loading:


Save the changes to the plugin’s settings, and you’re good to go. If you want to disable deferred loading for a specific element, open the editor and select the image or video block that you want to configure.

Open the block settings menu and navigate to the Advanced tab to find the Additional CSS class(es) field:

You can use that field to add the lazy-loading exclusion class that you set up while configuring the plugin. If you do this, that image will load instantly when a user visits your site.

Troubleshooting Lazy Loading Issues

Although deferred loading is handy and a core feature in WordPress, it can also lead to several types of errors within your website. This section will discuss what those issues are and how to troubleshoot them.

Problems With Images Above the Fold

Generally speaking, we recommend that you don’t lazy load images above the fold. When we say “above the fold”, we mean the first viewport that your visitors see when they load a page from your website.

Deferring images above the fold can impact your FCP scores. It can also affect users’ first impressions when they visit your website.

The simple solution is to disable deferred loading for images in your page headers and other top elements. If we take this page, for example, we’d recommend disabling lazy loading for (1) the logo and (2) the header background:


WordPress requires you to add code to your website to disable its native implementation of lazy loading. The easiest way to turn off deferred loading for specific media assets is to use a plugin such as a3 Lazy Load, as we explored in the last section.

Layout Shifting Due to Deferred Loading

Layout shifting happens when you’re loading a page and elements move around as they become visible. The Cumulative Layout Shift (CLS) is a Core Web Vital that measures layout shift. In some cases, poor implementation of lazy loading can impact your website’s CLS scores.

Elements on a page don’t load all at once. Instead, they come through one by one, even if the process looks near-instant on a browser. When you have image files that load after other elements, they can move those assets around.

The solution to that problem is to avoid using full-size images in WordPress. When you upload pictures to WordPress, the CMS will automatically resize them to standardized resolutions:

Using standard resolutions reduces the likelihood of drastic layout shifts even with deferred loading. You can also specify image dimensions manually for each file. However, that’s a time-consuming process. In short, we only recommend doing it for images that you want to show in unique dimensions.

Problems With Deferred Loading and Caching Plugins

It’s common for caching plugins to conflict with lazy loading tools. Some caching plugins, such as WP Rocket, include built-in delayed loading functionality. Using that feature with a deferred loading plugin, such as a3 Lazy Load, will often lead to conflicts.

We recommend sticking with one family of plugins to avoid problems with images not showing up due to conflicting tools. If you have both lazy loading and caching plugins enabled and you start running into errors, we recommend deactivating the former option first:

After disabling the lazy loading plugin, check to see if your images are loading correctly. If that’s the case, your caching tool probably comes with built-in delayed loading functionality. That means you don’t need to set up any additional software for that feature.

End review

Albeit apathetic stacking is essential for WordPress’ center elements, there are ways of further developing its execution. You can utilize modules, for example, a3 Lazy Load to have more command over deferred stacking on your site. With the right module, you can likewise arrange and reject conceded stacking for outside resources.

Contingent upon how you carry out sluggish stacking, the training ought to radically diminish page stacking times. The more media-weighty your site is, the better the outcomes you’ll see – all of that with next to no adverse consequence on the client experience.
