Optimization Features

Argo Smart Routing

Argo improves performance by routing visitors through the least congested and most reliable paths using Cloudflare's private network.

AMP Signed Exchanges

AMP Real URL provides signed exchanges for AMP enabled pages, which allows you to retain the URLs for your content when displayed in AMP search results.

Rocket Loader

Local Storage Caching

Uses local storage on modern browsers and mobile devices to intelligently cache the objects needed to best render your site.

Cache Header Optimization

Automatically adjusts the cache header instructions so browsers will correctly cache the resources of a site to minimize the need for new requests.

HTTP/2

The latest version of HTTP speeds up content delivery with multiplexing, header compression, stream priority and more. Server initiated resource prioritization for high value assets further improves page load times.

Easy On and Off

Cloudflare services are easy to turn on or off. Want to try one of the services? It is one click to turn on. Want to turn one of them off? It is one click simple.

Server Push

HTTP/2 Server Push allows a server or edge network to send assets to the browser before it even asks for them.

AutoMinify

On-the-fly removal of unnecessary characters from HTML, CSS, and JavaScript. Can save 20% of a file’s size and works without caching so it can support even fully dynamic pages.

Automatic HTTPS Rewrites

Eliminates mixed content issues while enhancing performance and security by rewriting insecure URLs dynamically from known hosts to their secure counterpart.

Browser Optimization

Automatically adjusts the way content is delivered based on the particular device accessing the site to maximize speed without affecting the site’s look or features.

TLS 1.3

Transportation Layer Security (TLS) 1.3 reduces latency and removes insecure features of TLS, making HTTPS more secure and performant than any previous version of TLS and its non-secure counterpart, HTTP.

Opportunistic Encryption

Provides HTTP-only domains the benefits of encryption and web optimization features only available when using TLS.

Asynchronous Resource Loading

Asynchronous resource loading optimizes your HTML so it renders as quickly as possible without waiting for slow scripts like widgets or advertising. Your web pages will feel much snappier.
