This interface of cPanel helps you to enable gzip compression. Apache allows you to compress the data before sending it to the browser and then web browser extracts the data and displays the webpage. All modern browsers support gzip compression. This gzip compression needs Apache mod_deflateto function currently, which is available in most cPanel installed Linux servers. This compression is very useful, because it helps in compressing data hence our bandwidth is saved, plus it makes our website to load much faster.

You can compress specific types of MIME (Multipurpose Internet Mail Extensions) or you can compress all the files using this interface.
