Enable GZIP Output Compression

Snippets by IsItWP

Do you want to enable GZIP output compression to reduce the page load time and HTTP response time? While there’s probably a plugin for this, we have created a quick code snippet that you can use to enable GZIP output compression in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

if(extension_loaded("zlib") && (ini_get("output_handler") != "ob_gzhandler"))
   add_action('wp', create_function('', '@ob_end_clean();@ini_set("zlib.output_compression", 1);'));

Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.

  1. Wow, great tip. My personal WP blog is significant faster.

    One thing that I’m nervous is about to implement on the commercial site, is this effect to the google ranking?

    1. I find people say a wide range of things, i would just give it a try and use webmaster tools to check and make sure things are working properly if not then disable it if you have no problems run with it.
