How to enable Gzip Compression for WordPress.

If you want to increase your website’s performance and speed by reducing its load time on clients’ (i.e., visitors’) machines, then this tutorial will help you.

Something About WordPress:
WordPress does not offer a mechanism to compress the blog’s HTML output. The Apache-enabled web server normally provides this feature.

As the Apache Website Defines, The mod_deflate module provides the DEFLATE output filter that allows output from your server to be compressed before being sent to the client over the network.

Here is how to enable gzip compression via .htaccess
If you prefer to allow or fine-tune output compression with the Apache server, then copy and paste the below code into your .htaccess file:

<IfModule mod_deflate.c>
# Insert filters
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
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE application/x-httpd-fastphp
AddOutputFilterByType DEFLATE image/svg+xml

# Drop problematic browsers
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
</IfModule>

Success:
