Page Caching for Desktop and Mobile: Caching makes your loading site ultra-fast. WP Rocket caches your pages by creating static HTML files and making them readily available for future visitors. Cache Preloading: Let your visitors enjoy the speedier, cached content of your site right away. WP Rocket v3.11.5 automatically preloads the cache every time you make some changes on your pages.
WP Rocket creates a separate cache file to serve WebP images to compatible browsers. To ensure compatibility, it detects some of the common plugins you might be using for WebP.
