WP Fastest Cache Premium adds performance controls for WordPress page caching and resource delivery. Page caching stores static HTML versions of dynamic pages, which can reduce initial server response time and page load time. Automatic preload creates cache files across the website without waiting for visitors to open each page.

Cache creation and control

Set a general cache timeout or configure timeouts for specific pages. Mobile Cache creates files for mobile devices, while Widget Cache stores widget output. Settings let you enable or disable caching for mobile devices and logged-in users. You can exclude pages and visitor agents, or block caching on a particular page or post with a shortcode. Publishing a post or page clears cached files, and the extension settings let you clear cached files and minified CSS or JavaScript.

CDN and proxy cache support

The extension works with SSL and CDN integration, including Bunny CDN, Cloudflare, and other providers. CDN integration adjusts static resource URLs for delivery through the selected provider. When a cache purge is initiated, Cloudflare integration can clear its cache through the API. Proxy Cache supports Varnish Cache integration, clearing proxy-cached content when WP Fastest Cache clears its own cache.

Optimization tools

Premium options include Minify HTML Plus, Minify CSS Plus, and Minify JavaScript to remove unnecessary characters, comments, and whitespace from supported files. Combine JS Plus merges JavaScript resources, and Defer JavaScript is designed to eliminate render-blocking JavaScript resources.

• Optimize Images and Convert WebP
• Database Cleanup for revisions, trashed content, spam and trashed comments, transient options, and orphaned metadata or relationships
• Google Fonts Async and Lazy Load
• Delay JS
• Disable Emoji, which removes the emoji inline CSS and wp-emoji-release.min.js

These options can be used with Gzip compression, browser caching, expires headers, CSS and JavaScript combination, and page caching. Settings allow you to pick which optimizations fit the site’s theme, content, and delivery setup. Review changes individually and clear cached and minified files so the updated options can take effect. Using multiple caching add-ons at the same time can cause inconvenience; the plugin information advises disabling other caching add-ons while using WP Fastest Cache.
