Joomla GZip Compression: How to Check, Enable or Disable it

One of the things you must do to make your Joomla website faster is to enable Joomla Gzip compression. Essentially what this does is, is asks the server compress all the files before sending them to the user. Since the files are smaller, they take much less time to get delivered to the user, resulting in an overall faster experience for your user.

Let's take you through the whole process of checking whether Joomla GZip compression is enabled, and enabling or disabling it. We will also show you how to enable it via your hosting server CPanel.


Check whether Joomla already has GZip compression

Before you actually go and do any changes, you probably want to check whether your site gzip page compression Joomla is enabled. This Gzip Compression test will give you some good statistics on the results of the compression. There are a few other sites such as the HTTP Compression test. Run your site through the gzip compression test.

Disabling page compression is, of course, the reverse of what we just did at the top. Go to System > Global Configuration > Server and switch to No, then Save. Run the gzip compression test again to verify that page compression has been disabled.

Enabling GZIP Page Compressions for all Joomla and other sites on your hosting server

Besides enabling GZip page compression at Joomla level, you can choose to do this at the server level - if available. This means that all websites hosted on your server would now be fully gzip enabled. 

Look for the "Optimize website" icon on your Cpanel and click on it.

Once you are in the Optimize Website on CPanel, you can choose to "Compress All content". This asks your server to gzip compress the content before sending it to the visitor. Of course, if your Joomla is hosted here, you can rest assured that your content is also Joomla gzip-compressed.
