How To Lazy Load Images In WordPress Site

Don’t know, how to lazy load images in WordPress Site? You have come to the right place to know all about it.

Lazy load functionality allows your WordPress site or blog to load images from the server, only when a person scrolls down to those specific images. Due to this functionality your blog’s load time is reduced drastically, which in-turn improves the performance.

Websites or blogs that are image heavy can use this functionality to speed up their performance. In this article, we will show you how to easily lazy load images in WordPress site or blog.

Please note that, the release of WordPress 5.5 added the lazy load feature by default. Having said that, if you want to customize how your images lazy load, and lazy load background images, then you’ll need to use a WordPress plugin.

Why Lazy Loading Of Images Is Required

As you might know that, images take the most time to load as compared to other web elements.

Lazy loading your images can speed up your WordPress website or blog & offer a much better user experience to all the people that visit them.

Websites or blogs that load slow, can kill your money making opportunities.

A research study suggests that a single second delay in the loading time leads to 7% less conversions, 11% fewer page views, and 16% decrease in customer satisfaction.

Besides, search engines like Google do not like slow loading websites or blogs either.

Their algorithm is well equipped to rank the slow loading websites or blogs much lower in the search results.

You can handle this by using a Content Delivery Network (CDN).

But that will solve only half the problem, as the images closer to the location where the audience is viewing them will only load faster.

Images that are at far away location from your audience will still take time to load

This is exactly why, you need the lazy load functionality for your website or blog.

How Does Lazy Loading For Images Work?

Now, when someone requests for a page to be viewed by opening a website or by clicking on a link, that request is sent to the server & then page is retrieved from that server. While this entire process is going on, all the images tend to load at once. This causes the website to load slower.

If a functionality is added to your website or blog which allows all your images to load lazy rather than loading all at once, then it can save a lot of time. So, with lazy load, the website or blog loads images only the audience scrolls down to those images. Not just the time is save in loading your images, but also the bandwidth is saved resulting in reduced hosting costs.

One important thing to remember here is that, though lazy load functionality helps you to improve website or blog’s loading speed, you should always optimize your images before uploading them.
