What is GZIP Compression?

GZIP compression is a technology that compresses data files before it is sent to users’ browsers. This reduces the file download time which makes your website faster.

Once the compressed data arrives, all modern browsers automatically unzip the compressed files and display them. GZIP compression doesn’t change how your website looks or functions.

It just makes your website load faster.

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

How does GZIP compression work?

Gzip compression uses compression algorithms that work on 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 data size, the compression can reduce file sizes by up to 70%.

This is why most website speed test tools like Google Pagespeed Insights highly recommend enabling gzip compression. These tools will also show a warning if gzip compression is not enabled onn your website.


Note: By default, Gzip compression does not compress images or videos. For that you’ll need to optimize images for web on your WordPress site.
