How to enable Gzip compression?
Enable compression via .htaccess
For most people reading this, compression is enabled by adding some code to a file called .htaccess on their web host/server. This means going to the file manager (or wherever you go to add or upload files) on your webhost.
The .htaccess file controls many important things for your site. If you are not familiar with the .htaccess file, please read my working with .htaccess article to get some know how before changing it.
The code below should be added to your .htaccess file…
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
Save the .htaccess file and then refresh your webpage.
