<ol>
<li>Page Caching – Page caching feature generates and store static HTML files from your dynamic WordPress blog to reduce initial server response time, and improving page load time. Page cache and caching play a critical role in improving website speed and overall web performance. By storing frequently accessed data, effective caching reduces server workload and significantly improves cache performance, allowing pages to be delivered faster to users. This optimization directly lowers load time and enhances page speed, resulting in a smoother user experience and better SEO.</li>
<li>Minify Html – Using an HTML minifier is an effective way to reduce HTML size and optimize HTML by removing unnecessary spaces, comments, and line breaks. A smaller HTML file helps reduce page size, which directly improves page speed and leads to a faster website experience for users. By focusing on web performance optimization, optimized HTML allows browsers to load and render pages more efficiently, helping to improve website speed, lower bandwidth usage, and deliver better overall performance across all devices</li>
<li>Minify Css – CSS minify techniques play a crucial role in modern web development by reducing unnecessary characters through a reliable css minifier. With effective css compression, developers can compress CSS files and apply proper css minification to optimize CSS for production environments. This approach helps reduce CSS file size, which directly contributes to improve website speed and overall css performance optimization. As part of a broader page speed optimization strategy, these practices significantly enhance website performance optimization and lead to better website loading performance, especially on mobile and low-bandwidth connections</li>
<li>Enable Gzip Compression – Reduce the size of files sent from your server to increase the speed to which they are transferred to the browser</li>
<li>Leverage browser caching – Browser cache plays a critical role in how efficiently a web browser cache stores static resources like images, stylesheets, and scripts, directly impacting page load speed. By allowing returning visitors to load files from their local browser cache instead of downloading them again, websites can significantly reduce server requests and improve website speed. Properly configured browser caching not only creates a faster and smoother user experience but also helps lower bandwidth usage and enhance overall site performance</li>
<li>Combine CSS – Reduce number of HTTP round-trips by combining multiple CSS resources into one</li>
<li>Combine JS – Combining JavaScript files is a core technique in javascript optimization and js optimization, especially when the goal is to reduce requests and improve page load speed. By combine js assets or combine javascript files into a single bundle, developers can streamline how scripts are delivered to the browser. Whether you call it js combine or javascript combine, the idea is the same: fewer HTTP requests mean faster performance. Similarly, approaches that merge js or merge javascript—also known as js merge or javascript merge—help eliminate overhead caused by loading multiple separate files. When done correctly, combining and merging scripts leads to cleaner delivery, better caching, and noticeably faster websites</li>
<li>Disable Emoji – You can remove the emoji inline css and wp-emoji-release.min.js</li>
</ol>
<h4>Premium Performance Optimization</h4>
<p>The free version is enough to speed up your site but in the premium version there are extra features 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, Lazy Load and Delay JS for super fast load times.</p>
<ol>
<li>Mobile Cache</li>
<li>Widget Cache</li>
<li>Minify HTML Plus</li>
<li>Minify CSS Plus</li>
<li>Minify Javascript – Minify JS is a core step in web performance optimization because js minify techniques remove unnecessary characters, comments, and whitespace, making files smaller and faster to load. Through proper javascript minification, developers can compress JavaScript assets and significantly reduce transfer size, which directly supports effective js optimization and overall javascript optimization strategies. When combined with caching and code splitting, minified scripts help improve website speed, lower bandwidth usage, and enhance user experience. As a result, page speed optimization becomes easier to achieve, leading to faster render times and better search engine rankings.</li>
<li>Combine JS Plus</li>
<li>Defer Javascript – Eliminate render-blocking JavaScript resources. Consider delivering critical JS inline and deferring all non-critical JS</li>
<li>Optimize Images – Optimized images load faster and consume less cellular data. Looking for an easy image compressor? Our tool lets you compress images instantly, including Compress JPEG and Compress PNG options. Enjoy fast image compression to reduce image size without losing quality. Perfect for quick image optimization with a smart image optimizer designed for all your needs.</li>
<li>Convert WebP – Serve images in next-gen formats. Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. A fast and reliable WebP converter helps you convert to WebP in seconds. Whether you need a WebP convert tool, a JPG to WEBP Converter, PNG to WEBP Converter, or a simple image to WebP option, you can easily optimize your images. Quickly handle JPG to WEBP, PNG to WEBP, jpg convert to webp, and png convert to webp tasks to reduce file size and improve web performance.</li>
<li>Database Cleanup – To keep your system running smoothly, it’s important to clean database structures regularly and ensure you clean DB records that are no longer needed. A database cleaner is essential for effective database cleaning and long-term database optimization. By removing unused entries and organizing data efficiently, you can significantly improve database performance and speed up database operations. Modern db cleaner tools automate the entire db cleaning process, helping developers maintain fast, reliable, and scalable systems. The Database Cleanup feature clears out all of the garbage datas such as post revisions, trashed posts & pages, comments from trash & spam, trackbacks and pingbacks, transient options, orphaned post meta, comment meta, user meta, term meta, and term relationship etc.</li>
<li>Google Fonts Async</li>
<li>Lazy Load – Lazy loading technique improve page speed and overall website loading time by loading content only when it is needed. Using lazy load images, lazy loading images, lazy load videos, and lazy load iframe helps reduce initial load size, enhances web performance, and delivers a smoother user experience. When implemented correctly, these methods make it easier to optimize website performance, lower bandwidth usage, and ensure faster, more efficient page delivery for both users and search engines.</li>
<li>Delay JS – The Delay JavaScript feature helps reduce the ‘Reduce unused JavaScript’ warning in the Google PageSpeed Insights tool</li>

WP Fastest Cache – WordPress Cache Plugin


The truth is that it is a pity that despite being a very good cache plugin, it only works for websites with one language.Confirmed with support that it does not pre-cache alternative urls to the native language of the website.


good plugin but... No languages?


I have tried so many different caching/optimization plugins and while others are bringing the page loading speed down to max 2.5-3 seconds WP Fastest Cache has really brought my website to 1.5 seconds loading time, this plugin is really the fastest caching plugin available it is incredibly good!


Really the fastest caching plugin (I've tried them all)


this is our favorite plugin for speeding up wordpress websites. works out of the box. 



we are also premium-users and it is worth the money!


great performance, great support


The support team is not only charming but also exceptionally helpful.


Amazing Support Team: Friendly and Helpful


Thank you so much for the amazing plugin you built, it works great with many project types!


Amazing Plugin

Prompt support


WP Fastest Cache works great on cloudways hosting, with support of varnish cache, it is even better than the recommended cache plugin created by cloudways.


Great plugin


It would be better if this plugin had some default settings not to cache EVERYTHING. Like doesn't matter if you have some important parameters in URL because it's the search results page - it will be cached and broken by default. 


Probably worst cache plugin you can choose

La mejor que he probado


I really enjoy using this wp-fastest-cache plugin. It is super easy to use and really helpful in speeding up the site.


Really love it.


I'm really impressed with their customer support, will highly recommend it!


Great Support and Quick Responses


WP Fastest Cache is solid for boosting site speed! Love the mod_rewrite approach and auto-cache clearing when you publish posts. CDN integration with Cloudflare/Bunny is smooth, plus the preload feature is handy. BUT heads up - it can mess with analytics by caching AJAX/JS requests. You can add filter rules but they don't always work perfectly. Great for speed, just watch your stats!


Speed Demon with a Few Quirks


Just installed and set some settings and runs like smooth. It actually works, If you know how, you'll be up/running in no time. This is a great plugin!


It works out of the box


As a developer, I appreciate plugins that deliver performance without bloat—and WP Fastest Cache nails it. It’s lightweight, easy to configure, and significantly boosts page load times out of the box. The minification, GZIP, and browser caching features just work as they should. If you need reliable caching without the overhead, this is your go-to.


Solid, Lightweight Caching That Just Works


I really like how easy it's to setup and it works great on Apache, NGINX and OLS. When I had an issue with a license, support was fast and great and I recovered access to the license without any problem.
