Find out how to Allow GZIP Compression in WordPress (three Methods)

Would you like to enable GZIP compression in WordPress? GZIP compression makes your website faster by compressing the data and delivering it quickly to the user’s browsers.

A faster website improves the user experience and brings more sales and conversions to your business.

In this article, we’re going to show you exactly how you can easily enable GZIP compression in WordPress.

What is GZIP Compression?

GZIP compression is a technology that compresses data files before they are sent to users’ browsers. This will reduce file download time, which will make your website faster.

As soon as the compressed data arrives, all modern browsers automatically unzip the compressed files and display them. GZIP compression does not change the appearance or function of your website.

This will only make your website load faster.

GZIP is supported by all major web browsers, server software and all of the best WordPress hosting companies.

How does GZIP compression work?

Gzip compression uses compression algorithms that work for website files like HTML, CSS, JavaScript, and more. When a user requests a page from your website, the algorithm sends the output back in a compressed format.

Depending on the data size, compression can reduce the file size by up to 70%.

For this reason, most website speed test tools like Google Pagespeed Insights recommend enabling gzip compression. These tools also display a warning if gzip compression is not enabled on your website.

Note: By default, Gzip compression does not compress images or videos. To do this, you need to optimize images for the web on your WordPress site.

Why do you need to enable GZIP compression in WordPress?

Simple raw data takes longer to download, which affects the speed of your page loading. Having multiple users arriving at the same time will further slow down your WordPress website.

GZIP compression allows you to transfer data efficiently, increase page load times, and reduce the burden on your website hosting. This is an essential step in improving your website’s speed and performance.

Now you might think that GZIP sounds very technical and complicated. However, there are plenty of WordPress plugins that allow you to add GZIP compression to your WordPress website with ease.

In some cases, GZIP may already be enabled by your WordPress hosting company.

Bluehost, an officially recommended WordPress hosting provider, automatically enables GZIP compression on all new WordPress sites.

To test if GZIP is enabled on your site, simply go to this GZIP tester and enter your site’s url. If GZIP is working on your site, you will see the message “GZIP is enabled”.

Use a GZIP test tool to determine if GZIP is enabled on the specified website
