About Check GZIP compression

How Does This Test Work?

This test will check whether your website(and ultimately the server you are hosted on) has gzip enabled by connecting to your domain and requesting the necessary information. Next to that it will also give you some additional information like the size of the original version of the web page you tested and how much you (may) benefit from using gzip compression.

What Does Gzip Compression Do?

Gzip compression makes it possible to compress your web files (mainly HTML, CSS, and JS files), sometimes up to 70%-80%. This much smaller compressed version of the file is then sent to the browser of the visitor instead of the larger original file. The browser of your visitor will then automatically decompress the compressed file and serve the uncompressed original file to your visitor.

How Does Enabling Gzip Make My Website Faster?

The Gzipped file is much smaller in size (in bytes) as your original web file. The browser of your visitor will need less time to load your website because it only needs to download much smaller files.
