What is GZIP Compression?
GZIP is a file format and a software application used for file compression and decompression. Web servers or other software use GZIP compression to compress data files before it is sent to users’ browsers. This reduces the file download time which makes your website faster. All modern browsers support GZIP compression.
It’s also important to note that GZIP compression must be enabled on your web server before you can enable file and folder compression. Shortly, we’ll see how to verify whether your web server has GZIP enabled.
How does GZIP Compression Work?
When a web server receives a request for a web page, the webserver checks the header of the request to check if the browser supports Gzip. If so, the server generates the markup for the page before applying GZIP. Gzip converts the HTML markup into compressed data which is then delivered to the end-user. When the end-user receives the compressed data, their browser decompresses it.
How to verify if GZIP Compression is Enabled?
Your web host might enable compression in WordPress by default. However, this isn’t always the case. You can determine to see if you already have GZIP compression enabled using Chrome’ DevTools.

# BEGIN WordPress and
# END WordPress tags
Save the file and upload it to your site’s server. When you’re done, check if the GZIP is enabled using Chrome’s DevTools as explained above.
