Website Optimization Services

Delivering fast web experiences is not just about moving files closer to your visitors.

It’s about ensuring the first pixels load on your visitors’ screens as quickly as possible. It’s about optimizing the order of page resource delivery to make the page visible and usable faster.

And it’s about knowing when and why your webpages are rendering slowly, and what you can do about it.

Gauge how fast your website is. And how you can make it even faster.

Browser Insights

If you can’t measure it, you can’t improve it.

Measure the real user experience of your website as well as the performance benefits of using Cloudflare.

Browser Insights lets you measure the TCP connection time, DNS response time, Time to First Byte (TTFB), page load time, and more from the perspective of your visitors all over the globe.

The Speed Page on your dashboard also generates a filmstrip of screen snapshots taken as your webpage loads. This gives you a visual comparison of your website loading on Cloudflare with caching enabled compared to connecting directly to your origin.

Image Optimization

Images bring your webpages to life, but large-sized images often slow down webpages. Additionally, creating and managing multiple image variants for mobile and desktop can be complex.

Cloudflare Image Optimization algorithms make image delivery seamless, taking the complexity out of the picture.

Create bespoke image variants from a single primary image using Image Resizing, or streamline image delivery for mobile using Mirage, or use simple image compression with Polish.

Image Resizing

Creates high-quality image variants using a single primary image from your origin. Resize, crop, compress, or convert images to WebP to reduce bandwidth costs and increase performance.


Accelerates image delivery for your visitors based on their device. Mirage detects screen size and connection speed to optimally deliver images for the current browser window.


Reduces the image size by stripping metadata and applying lossless or lossy compression to remove redundant bytes from images.

Enhanced HTTP/2 Prioritization

Webpages are made up of dozens (sometimes hundreds) of separate resources that are loaded and assembled by the browser into the final displayed content. The sequencing of how those resources are loaded can have a significant impact on how long it takes for the visitor to see the content and interact with the page.

Optimize the order of resource delivery, independent of the browser. Enhanced HTTP/2 Prioritization overrides the browser defaults with an improved scheduling scheme that results in a significantly faster visitor experience.

Other Optimization Features

Rocket Loader

Prioritizes the loading of text, images, and fonts on your webpages by deferring the loading of render-blocking JavaScript.

TCP Turbo

Chooses the custom-tuned TCP settings to reduce latency and increase the throughput of connections.


Removes unnecessary characters from JavaScript, CSS, and HTML files.


Lossless compression algorithm reduces the size of your cached HTTP/S pages.
