How to Enable Gzip Compression for WordPress via .htaccess file? Print

  • 2

When Gzip compression isn't enabled on the WordPress website, Google PageSpeed Insight gives you the warning to Enable Compression. There are a couple of ways you can fix this warning. The first, and one of the easiest, is using a caching plugin that supports enabling Gzip.

You can enable Enable HTTP (gzip) compression through caching plugins like W3 Total Cache or a specific compression plugin like GZip Ninja Speed Compression. Alternatively, you can enable Gzip compression by editing your .htaccess file.

1. Log into your cPanel.

2. Under the Files section, select the File Manager menu.

3. cPanel will pop up a message asking where you would like to land within your website directories.
In the same window, you will see the checkbox asking if you want to show hidden files. Check the checkbox Show Hidden Files and click Go.

4. Under the public_html folder of your website, find and edit the file called .htaccess.
Paste the following code into the .htaccess file at the end of your existing content.

<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
