8 Best Plugins for WordPress Site Speed Up

Below, I am going to mentions some powerful plugins to accelerate your WordPress site speed immediately.

Note: You need quite technical knowledge to configure the cache plugin with your WordPress site. Before installing any cache plugin, take site backup.

W3 Total Cache

W3 total cache is the most popular cache plugin; it is beyond a simple cache plugin. It offers various levels of caching options with easy to embed third-party services like CDN features.

On the contrary, some W3 features are quite difficult to integrate, so if you don’t know, How to do this, then you need a WordPress developer to do it for you.

Whether you configure W3 Total cache plugin yourself, make sure you will not do anything wrong. if you will do something wrong, it breaks your site.

W3 Total Cache Plugin Features

  • One-click browser cache clear

WP Super Cache

WP Super Cache plugin is the best alternative to the W3 Total Cache plugin. It has more than 5.5 million active installations with more than 4 ratings in the WordPress plugin directory. 

In other words, the WP Super Cache plugin is the most noteworthy and top-rated WordPress Cache plugin.

WP Super Minify allows you to combine them and reduce that file size for improving WordPress site speed.

However, when setting this plan, you need to pay attention to it. Because in the past, I have found this plugin was the conflict with some themes and plugins.

WP Super Minify

  • Combine JavaScript’s, CSS and HTML files
  • Option to discard unnecessary CSS and java Scripts files
  • Easy to use and integrate with other security and speed up plugins

WP Fastest Cache

Cache Enabler is the lightweight and easy to use cache plugin offered by the team KeyCDN. 

Cache Enabler has plenty of extra features than other plugins like automatic cache expires and minifies javascript and CSS.

However, this plugin has one con than other plugins that is no CDN integration feature. If you want to integrate CDN with this plugin, then you need to install one more plugin of team KeyCDN that is CDN Enabler.

WP Smush is the image optimization plugin for use to remove unnecessary bytes from the image file size. Most of the image optimization plugins provide a Lossy compression format, and this format degrades image quality too. However, Smush offer “Lossless” format optimization, in this format, only image file size reduction, but the image quality will remain the same as the original image.

  • WP Features
    • Without effect on image quality reduce the image file size
    • Optimize all types of images such as JPG and PNG format
    • Easy to integrate with API
    • Able to optimize already used images in bulk action

Imagify – The Number #1 Image optimization plugin

Imagify is the number #1 image optimization plugin in the WordPress directory. It offers 3 levels of image file size optimization options, which are Normal, Aggressively, and Ultra. I personally use, aggressively optimization feature. In this format, without losing image quality, you can reduce image file size.

  • One-click set up a facility
  • Reduce image file size up to 90%

LazyLoad plugin by WPRocket

If you publish long in-depth blog posts including lots of images and videos. When users visit our website, typically, your website will load with all elements of your blog post including images and videos together. Certainly, your website will load slowly.

Better than loading all images together, you can use a lazy load plugin for images like Lazy Load Plugin by WP Rocket. This plugin only loads images that will be displayed on the user’s screen.

One more advantage of using LazyLoad Plugin by WpRocket is, this plugin replace YouTube iframes with video preview thumbnails.

These plugins have more active users than other speed optimization WordPress plugins. Almost all cache plugin provides easy to integrate CDN facility, so use CDN with a cache plugin for better performance.
