SSS

What is defer.js?

🥇 Defer.js is an exceptionally lightweight, native performance library designed for lazy-loading resources such as JS, CSS, images, and iframes.

With Defer.js, you can easily enhance your website’s speed.

Why should I implement lazy-loading?

Loading all page contents at once can slow down your website’s loading speed. Users dislike staring at a blank white page and tend to leave quickly.

Implementing lazy loading can alleviate resource contention, resulting in improved performance.

Why should I use this plugin?

This plugin offers practical solutions for optimizing on-page resource downloads, based on recommendations from Google Developers available at this website.

You could manually implement these optimizations, but it’s time-consuming and requires expertise.

How does this plugin function?

This plugin optimizes a wide range of elements, including image tags, videos, audio, iframes, stylesheets, and JavaScript.

It incorporates best practices endorsed by experienced web experts and leverages the latest web technologies for lazy-loading resources.

This includes features like creating “data-src” attributes for media and utilizing the loading=”lazy” attribute recently introduced by Google Developers.

High performance and precision

Additionally, this plugin utilizes the DOM to analyze website structure, delivering precise results and outperforming other plugins that rely on HTML text processing.

Give it a try, and you’ll likely be pleasantly surprised by the performance improvements it brings to your website.

What about performance and compatibility?

We’ve thoroughly tested this plugin alongside numerous others and haven’t encountered any significant conflicts.

For optimal use of this plugin, consider disabling other optimization features (e.g., lazy-loading, HTML minification, JS minification) offered by other plugins.

We also recommend using it in conjunction with a page-caching plugin for the best performance.

Plugin is not supported and score on Google Page Speed test and Gmetrix test is better without this plugin...

I am very happy and satisfy with it, it's a lightweight and very promising plugin. Just install the plugin and keep everything default, It will boost your page speed significantly. In some cases, you can manually exclude by CSS class if you have elements that don't want to be lazyloaded. The developer is a very responsive and quick reply. I am using oxygen builder, If it has a pro version (lifetime deal) for early birds adopters, I'd like to buy it. Great plugin! deserver 5 stars!

incredibly practical and efficient

easy configuration and very efficient performance plugin. It was the only plugin that really managed to make an efficient defer and lazy on my site, without errors! my lighthouse score for Mobile devices jumped from 22 to 84 by combining this plugin + plugin unload feature by Asset Cleanup Pro. Note: for those who use Cloudflare, it will be necessary to disable "mirage" if you want to use the plugin's lazy (it seemed more efficient than Mirage cloudflare)
