Overview

This interface allows you to configure your server to automatically compress specified types of content when visitors access that content.

Manage compression

To disable compression of your website’s content, perform the following steps:

To compress all of your website’s content, perform the following steps:

Select the Compress the specified MIME types option.
In the MIME Types text box, enter a space-separated list of the types of content that you wish to compress (for example, text/html text/plain text/xml).
Note:
- Image file formats (for example, .jpg and .png) already compress data. Do not include any image file formats in the list.
- Apache will compress PHP content if you enable the zlib.output_compression setting in cPanel’s MultiPHP INI Editor interface (cPanel » Home » Software » MultiPHP INI Editor).

Note:

cPanel saves your settings to a .htaccess file in your home directory. Your system administrator customizes these settings with the Apache FileMatch directive.
