Enable Apache Gzip Compression (mod_deflate) in cPanel Account

Apache mod_deflate module is used for compressing content before serving to client. You can configure compression only if your hosting provider has enabled the mod_deflate module in Apache.

The WHM administrators can enable Gzip globally for all cPanel accounts using WHM control panel. Non cPanel users can enable gzip in Apache web server or Nginx web server using command line.
