 # What will Cloudflare compress?
 
+Cloudflare supports content compression both when delivering content to your website visitors and when requesting content from your origin server.
 
+## Content compression from the Cloudflare network to website visitors
 
-In addition to Cloudflare's [CDN](/cache/) [caching static content](/cache/concepts/default-cache-behavior/) and [auto-minification](https://support.cloudflare.com/hc/en-us/articles/200168196-How-do-I-minify-HTML-CSS-and-JavaScript-to-optimize-my-site-) of CSS, JS & HTML to speed up your site, Cloudflare also provides gzip and brotli compression to help site owners.

-For responses with error status codes, Cloudflare will only compress responses if their error status code is `403` or `404`. For successful response status codes, Cloudflare will only compress responses if their status code is `200`. Responses with other status codes will not be compressed.

-If you do not want a particular response from your origin to be encoded, you can disable this by setting `cache-control: no-transform` at your origin web server.
+Cloudflare's global network can deliver content to website visitors using gzip compression, [Brotli compression](#enable-brotli-compression), or no compression, according to the values visitors provide in the `Accept-Encoding` request header.
+
+For responses with error status codes, Cloudflare will only compress responses if their error status code is `403` or `404`. For successful response status codes, Cloudflare will only compress responses if their status code is `200`. Responses with other status codes will not be compressed.
+
+### Enable Brotli compression
 
-___
+By default, Brotli compression is enabled for domain on Free and Pro plans and disabled for domains on Business and Enterprise plans.
 
-## Does Cloudflare compress resources?
+To enable Brotli compression:
 
-Yes, Cloudflare applies **gzip** and **brotli** compression to some types of content. We also gzip items based on the browser's UserAgent to help speed up page loading time.
+1. [Log in to the Cloudflare dashboard](https://dash.cloudflare.com/), and select your account and website.
+2. Go to **Speed** > **Optimization**.
+3. For **Brotli**, toggle the switch to **On**.
 
-If you're already using gzip we will honor your gzip settings as long as you're passing the details in a header from your web server for the files.
+---
 
-Cloudflare only supports the content types **gzip** towards your origin server and can also only deliver content either **gzip compressed**, **brotli compressed**, or **not compressed**.
+## Content compression from origin servers to the Cloudflare network
 
-Cloudflare's reverse proxy is also able to convert between compressed formats and uncompressed formats, meaning that it can pull content from a customer's origin server via gzip and serve it to clients uncompressed (or vice versa). This is done independently of caching.
+When requesting content from your origin server, Cloudflare currently supports gzip compression or no compression.
 
-{{<Aside type="warning">}}
-The `Accept-Encoding` header is not respected between Cloudflare and the origin, and will be removed.
-{{</Aside>}}
+If your origin server responds to a Cloudflare request using gzip compression, we will keep the same compression in the response sent to the website visitor if:
 
-___
+* You include a `Content-Encoding` header in your server response mentioning gzip compression.
+* The client supports the compression algorithm.
 
-## Enable Brotli compression
+Cloudflare's reverse proxy can also convert between compressed formats and uncompressed formats. Cloudflare can receive content from your origin server with gzip compression and serve it to visitors uncompressed (or vice versa), independently of caching.
 
-By default, Brotli is enabled for domain on Free and Pro plans and disabled for domains on Business and Enterprise plans.
+If you do not want a particular response from your origin to be encoded with gzip/Brotli when delivered to website visitors, you can disable this by including a `cache-control: no-transform` HTTP header in the response from your origin web server.
 
-1.  [Log in to the Cloudflare dashboard](https://dash.cloudflare.com/), and select your account and website.
-2.  Click the **Speed** app.
-3.  Click the **Optimization** tab.
-4.  Toggle the Brotli switch to **On**.
+{{<Aside type="warning" header="Warning">}}
+Cloudflare will take into consideration the `Accept-Encoding` header value in website visitors' requests when sending responses to those visitors. However, when requesting content from your origin server, Cloudflare will send a different `Accept-Encoding` header, supporting only gzip compression.
