Enabling GZIP compression in OpenCart 1.5

OpenCart comes with the ability to enable GZIP compression. GZIP compression helps your pages load faster by compressing them when they are sent to the web browser to be rendered. When using the Google Page Speed tool, they recommend using compression. GZIP compression can be enabled through your OpenCart dashboard.

We do not recommend using compression unless you are on a VPS or dedicated server since enabling GZIP compression increases your server resource usage.

    1. Log into your OpenCart Dashboard
    2. Go to System > Settings
    3. Select your store by clicking “Edit” next to it
