Web content optimization

CloudFlare automatically caches your website's static content around the world, so it’s always close to visitors. True optimization, however, relies on much more. CloudFlare's suite of optimization tools ensures that every single webpage will load as efficiently as possible from any computer or mobile device, anywhere.

CloudFlare users may choose to use some or all of the optimization tools – turn on, test, or turn off at any time. The final decision always rests with you, the webmaster!

CloudFlare optimizer includes:

Rocket Loader™: Automatically minimizes the number of network connections and ensures third-party resources won't slow down page rendering. Rocket Loader is ideal for websites with ads, images, JavaScript, CSS, and third-party widgets.

JavaScript bundling: Cuts down on load time. Avoids the overhead of multiple network requests by bundling JavaScript files into a single request.

Local storage caching: Intelligently caches objects and files needed to render your site using local storage on modern browsers and mobile devices. Your data will always be available and accessible to visitors!

Cache header optimization: Minimizes the need for new requests. Automatically adjusts the cache header instructions so browsers will correctly cache the resources of a site for fast retrieval.

Asynchronous resource loading: Enables your HTML to render quickly, without needing to wait for slow scripts like widgets or advertising. Your web pages will feel much snappier!

Browser optimization: Automatically adjusts content delivery depending on the device accessing the site. This ensures maximum speed while maintaining the site's look and features – because every browser and every device works a bit differently!

Aggressive GZIP: Reduces the size of all your files and delivers them quickly, completely intact. Because making a website half as big is as good as making the network twice as fast!
