How to enable gzip compression via .htaccess

This manual is only for those, who runs pure Apache. In Apache + Nginx, gzip is activated by default.

.htaccess — Apache web-server configuration file. It controls many parameters of directories without interfering with overall server configuration. With .htaccess you can set access privileges, create error pages, control file and folder compression etc.

How to enable gzip compression?

  1. Log into cPanel
  2. On the dashboard, click on File manager.
  3. Go to the public_html folder.3
  4. By default, .htaccess is hidden. So click the Settings button and check the Show hidden files (dotfiles) mark.
  5. Now click on .htaccess and click Edit. 3d38405022

    AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
