WP-Optimize or WP Fastest Cache: Which is the better cache plugin?

Having a fast website is essential for any website owner. It not only helps with search engine rankings, but it also makes visitors more likely to stick around and explore your content.

Two of the most popular WordPress cache plugins are WP-Optimize and WP Fastest Cache. Both plugins have their own strengths and weaknesses, so it can be difficult to decide which one is best for your website.

As mentioned previously in this blog, both WP-Optimize and WP Fastest Cache are excellent plugins utilised and recommended by users worldwide. However, as one might anticipate, not all cache plugins are equal. While both plugins provide a paid edition with a slew of additional features and tools, this blog will compare the features accessible in their free versions.


What is a cache system?

Caching in WordPress is a vital technique that involves caching static versions of web pages for rapid retrieval and delivery to users. Caching greatly reduces the time and resources needed to load a webpage by creating pre-built pages, resulting in improved website speed and performance. This approach enhances user experience by minimizing loading times and also significantly contributes to improving SEO results as search engines prioritize fast-loading websites.

In addition, caching reduces the burden on the server by delivering cached content instead of producing it anew for each user visit. Incorporating caching in WordPress can result in enhanced page loading speeds, less server load, heightened search engine prominence, and ultimately an enhanced user experience for website visitors.


WP-Optimize is really amazing in its operation. The plugin is an all-in-one platform that enables you to quickly and easily accomplish the following tasks:

  • Cleaning up databases
  • Caching and minification of CSS and JS
  • Compression of images

With over one million active installations, WP-Optimize is a powerful, successful, and popular plugin that you should consider using to maintain your website in tip-top shape.

WP Fastest Cache

WP Fastest Cache is another well-known WordPress caching plugin, mostly for its simplicity. Although a free version is available, the major features that the majority of users will require – such as Mobile Cache, Widget Cache, Minify HTML Plus, Minify CSS Plus, Minify JS, Combine JS Plus, Defer Javascript, Optimize Images, Convert WebP, Database Cleanup, Google Fonts Async, and Lazy Load – are available only in the premium version.

The free version is sufficient if you’re looking to make some quick improvements to your WordPress site’s loading times. However, as someone who wants to optimise their site thoroughly, ‘fine’ is hardly the best compliment when other plugins can accomplish so much more.

Why is WP-Optimize a superior caching plugin to WP Fastest Cache in general?

It has more features

WP-Optimize includes more functions for free. Everything from picture compression to database cleaning and site caching is accessible on your WordPress site once WP-Optimize is installed.

WP Fastest Cache offers a fairly restricted set of functionality and makes the more helpful and critical ones available via a paid plugin.

WP-Optimize has a database optimisation function

WP-Optimize’s database optimization function allows users to clean up unnecessary data, such as post revisions, spam comments, and trashed items. By removing these unused data entries and optimising database tables, the plugin can help reduce the size of the database, leading to faster queries and improved website speed.

Further, optimizing the database can enhance overall site performance, and user experience, and even improve search engine rankings due to faster loading times.

WP-Optimize compresses the pictures on huge websites

WP-Optimize offers several compression options, allowing you to balance file size reduction with image quality. You can choose maximum compression for less important images or prioritise detail retention for crucial ones.

WP-Optimize can be configured to automatically compress images as you upload them to your website. This ensures that all your images are optimized from the start, preventing a backlog of unoptimized images on a large site.

This functionality is only available in the premium version of WP Fastest Cache.

WP-Optimize provides excellent customer assistance.

With over one million global users and thousands of 5-star reviews, WP-Optimize is dedicated to providing you with the greatest possible user experience.


We advise people to compare the performance of WP-Optimize and WP Fastest caches. While both plugins are incredibly popular and have their advocates and detractors, WP-Optimize offers a far more comprehensive set of critical functions that, when combined, may significantly improve your site’s performance. This can increase your SEO score, resulting in a higher Google ranking, increased success, and increased interactions with your visitors.
