Best WordPress Caching Plugins (2021)

Are you searching for the best WordPress caching plugins? Or only searching for ways to speed up your WordPress website? Read this blog and find the best WordPress caching plugins.

Either way, I’ve got you covered.

In this article, you'll discover 10 WordPress caching plugins that will help your WordPress website load faster. You can find plugins for caching, plugins for minifying, lazy plugins for loading, and some additional plugins that allow you to make different tweaks to your website.

So, because of slow page load times, you can lose traffic, members, and clients.

Let’s dive in:

The best wordpress caching plugins

1. WP Rocket


WP Rocket is the one of the best WordPress caching plugin to manage all of them.

Along with a lot of things you certainly wouldn't imagine, you get all the caching functionality you'd expect.

All bundled in the most user-friendly GUI that I've seen in such a plugin.

Where some caching plugins seem to need you to learn a whole course to find it out, by contrast, WP Rocket makes the configuration phase truly simple.

I love that it contains functionality with which you will usually have to install a few additional plugins. For starters, you get lazy loading of photos, optimization of databases, and even the ability to host Google Analytics code on your site.

And the opportunity to postpone the execution period of Javascript can have a major influence on website load times and ratings for Google PageSpeed.

If you want a pace enhancement addon that does it all, WP Rocket is well worth testing. I was able to remove 3 other plugins after downloading WP Rocket on one of my pages.


  • User-friendly interface
  • Minimal tweaking required for speed improvements
  • Minify CSS, HTML and Javascript
  • Page caching
  • Cache pre-load
  • Image lazy loading
  • Advanced caching rules
  • Database optimization
  • CDN integration
  • Direct Cloudflare integration
  • Google Analytics integration to load the code from your server
  • Settings import and export
  • Version rollback
  • Delay Javascript execution time

2. Perfmatters

perfmatters plugin

In optimizing page load times, Perfmatters takes a different path than other plugins on this list.

WordPress has certain options available by default, which are not sufficient for most sites and slow down efficiency. With the click of a few keys, Perfmatters helps you to uninstall these choices.

Although, HTTP queries that are not required are the main thing that threatens to bog down the rendering of your sites.

This plugin often enables these scripts to be removed on a per-page basis. This means you can avoid code from being loaded through plugins where it is not required.

You may also take advantage of features that improve efficiencies, such as DNS prefetch, preconnect, local hosting of Google Analytics scripts, and more.

So, even though you have built a WordPress caching plugin, you can still use Perfmatters.

Note: I was able to take one of my smaller pages from a page speed level of 59 to 90, using Perfmatters and WP Rocket. Not bad, huh?


  • Works with your existing caching plugin
  • Disable WordPress options that are slowing your site down
  • Disable scripts on per page/post basis
  • Supports advanced performance boosting functionality such as DNS prefetch and preconnect
  • REST API control
  • Heartbeat control
  • Lightweight plugin

Price: Starts from $19.95/year.Get Perfmatters

3. NitroPack


More than a WordPress performance mod, NitroPack is a full tool for speed optimization.

Simplifying the method of speeding up websites is the concept behind this platform. NitroPack optimizes it about you, instead of using multiple plugins and trying to manually select whether to customize.

Only link your website to it and mount the plugin adapter. You will then pick how aggressive the optimizations are for you to be.

NitroPack would then immediately begin optimizing the site. It would introduce a global CDN, multiple forms of caching, minification, compression, optimization of files, serving images in next-gen formats (e.g. SVG), DNS prefetch, JavaScript referencing, etc.

And their servers run all of these optimizations because it eliminates the use of your server.

Both of these adjustments will enhance first-byte time (TTFB), reduce main-thread function, enhance Site Core Vitals, and more.

You can adjust the settings to squeeze out still more results, but you can see big changes in page load times and Google PageSpeed scores even under the “solid” environment.

And, in our analysis, using Elementor, Colin was able to minimize load times by over 3 seconds. I was able to get my PageSpeed smartphone performance in the '90s using GeneratePress.

Note: There is a free plan, but it attaches the footer to a ‘driven by' badge. It is appropriate for the intent of small sites or research, but I suggest having a paid package to delete the badge.


  • Automatic website optimization
  • Supports WordPress and other content management systems
  • Global CDN included and automatically configured
  • Various caching types (page, browser, and more)
  • Automatic image optimization
  • Convert images to next gen formats
  • DNS prefetching
  • Defer JS loading
  • HTML, JS and CSS minification
  • HTML, CSS and JS compression

Price: Free plan available for very limited sites or research purposes, but attaches the footer to a powered badge. Paying schemes to delete the logo and include extra services. Try NitroPack Free

4. WP Fastest Cache

WP Fastest Cache is a plugin for consistency with an emphasis on caching. It comes with a fantastic range of characteristics that are matched with ease of usage.

Some plugins are too simple, others are too advanced-the middle ground has certainly been reached by the maker of this plugin.

Simply install, allow and run via the settings. Hit save then, and you're good to roll.

For some URL strings, I particularly like how simple it is to set cache expiration times.

And it's getting bigger because over 200,000 users use this plugin and get amazing feedback on


  • Easy setup
  • 1-click to clear cache and/or minified CSS etc
  • Minify CSS and HTML
  • Set posts/pages to exclude (some like admin area excluded by default)
  • Set expiration times for all posts/pages or certain URL strings
  • CDN integration
  • Premium version available with extra features

5. Cache Enabler

Cache Enabler is a fantastic plugin from KeyCDN's team.

It's a lightweight plugin for caching that can be set up in minutes.

The choice to set the cache expiry time, minification configuration, and a few other features come with the option. Other than that, the functionality is sparse, but that's the whole idea of this plugin.

If a content delivery network service has to be added, you can use a sister plugin named CDN Enabler. The same idea applies: lightweight and simple to customize.


  • Simple setup
  • 1-click to clear cache
  • Set cache behaviour (e.g. clearing after new posts)
  • Minification feature
  • Set post ID’s to exclude from cache
  • Set expiration times

6. WP Super Cache


One of the most commonly used caching plugins accessible for WordPress is WP Super Cache . It had over 5.5 million downloads at the time of writing this article.

It's simple to set up, but it has certain settings that can be used to get something out of the plugin for experienced users.


  • Support for multiple caching types (Mod_Rewrite, PHP and Legacy)
  • Serve static html files
  • Cache preload
  • CDN support

7. W3 Total Cache


 Another common speed improving plugin is W3 Total Cache. It goes beyond only being a simple plugin for caching.

There is a wide variety of alternatives and different types of caching that are assisted.

For Cloudflare and other CDN providers, there is specialized assistance.

Although, the fact is that it's not the simplest to set up since there are so many choices. And you could ruin anything if you don't know what you're doing. I suggest this plugin to experienced users for that purpose.

It is also worth mentioning that it may be tricky to remove this plugin-it takes longer to get rid of it than the usual deactivation and deletion.


  • CDN Support
  • Browser caching
  • Database caching
  • Object caching
  • Minifying
  • And lots more

8. WP Super Minify

The definition of minifying is to merge files from Javascript, HTML, and CSS so that they can be compact and served to guests in a manner that eliminates loading times for websites.

It is worth mentioning that when setting up these styles of plugins, you should be vigilant. In the past, I have noticed that often unique themes and plugins will clash with this form of a plugin.

WP Super Minify offers you the ability to disable JavaScript and/or CSS compression only if there are conflicts.


  • Minifies JavaScript, CSS and HTML
  • Option to disable compression of CSS/JavaScript
  • Extremely straight forward and easy to use.

9. WP

WP Smush is based on the Yahoo service, which is used to delete unwanted bytes from image files and improve images.

Most tools use lossy formats that reduce consistency, but WP Smush uses lossless formats such that no variation in quality can be observed.

In the past, I downloaded this plugin and discovered it to be quite buggy.

It broke all my picture thumbnails at the moment, but luckily there is a plugin named ‘Regenerate Thumbnails' that solved the problem within 5 minutes on my web, so no damage was done.

It is worth remembering that this occurred a long time ago and now WPMU DEV maintain the plugin.


  • Strips un-used colour from images
  • Strips meta data from JPEG’s (this isn’t needed anyway)
  • Optimizing JPEG compression
  • Integrates with the API
  • Choose to run existing images through the plugin

10. LazyLoad by WP Rocket

It would normally load the whole screen anytime a tourist enters your website and attempts to load a page.

This will cause the loading times to spike if it's a long page with loads of photos.

The reality is that you don't need to load the whole page at the same time, especially photos that typically take the most time to load.

The principle of ‘lazy loading' is that when they are required, particular elements are just prepared. And LazyLoad by WP Rocket is going to do it.

One fascinating aspect is that you can use preview thumbnails to cover your YouTube iFrames.


  • Replaces pictures for blogs, article thumbnails, etc.
  • No jQuery or Javascript is included since it is super lightweight.
  • It is possible to substitute YouTube iFrames with preview thumbnails

Bonus: 5 top tools to test the speed of your website

This article is more about showing you WordPress plugins that you use to cache your website, minifying your website elements, and setting up stuff like lazy loading, all plugins that can speed up your website's page load times.

And I was going to hold it that way initially, but I think it's important to share a few non-WordPress tools you can use to test your site's pace.

These kinds of tools function by merely inserting the URL of the website into the tool and running the test.

Here are 5 tools to get you started:

Choosing the right plugin for WordPress results

If you're struggling to speed up your installation of WordPress, only one of these plugins can increase your website loading times drastically.

It is necessary to find out that any of these should not be installed and you should not move further. Just install what you need and note that more is less. There are certainly other options to speed up the website, but some of these plugins are a fantastic way to get started.

The best efficiency improvement is given by NitroPack and optimizations are applied for you, like a global CDN. For tiny places, they have a free plan.

If you want to reduce costs but also substantially boosting page load times, WP Rocket and Perfmatters will be an efficient combination. Caching, lazy loading, and more, these optimization plugins will place a lot of features at your fingertips. And it's worth mentioning that WP Rocket is the only caching plugin they allow if you host with Kinsta.

I was able to take one of my smaller pages from a page speed ranking of 59 to 90, utilizing these two plugins. Fantastic.

On the other side, be sure to start with a caching plugin like WP Fastest Cache if you're searching for a free WordPress output plugin. And if you are a novice, it is easy to use.

There are loads of ways to speed up the website with WordPress. Next up, I suggest trying out our roundup of the best distribution networks of content (otherwise referred to as CDN's), which will significantly speed up website load times.
