How to Use Gzip Compression in Joomla 4

Introducing Gzip Compression

One of the things you can do to speed up your Joomla site is to enable the use of Joomla Gzip compression in Joomla 4. Roughly speaking, Gzip is a method to compress and reduce the size of files on the server before sending them to the client (e.g. the browser). It helps to save bandwidth, increase the loading speed of the website. It can compress static files such as Text, HTML, CSS, JavaScript, or some other documents such as XML or JSON. About images, media things that are usually not compressed by Gzip will be compressed by other methods and processed before uploading to the server. And since files are smaller in size, they also take less time to reach site visitors. Thus enhancing the performance of a website and creating a much better overall user experience.

The algorithm of Gzip is brilliantly simple. It locates similar strings and replaces them temporarily. The reason it works like a charm when applied to web pages is, HTML/CSS files use a lot of repeated text. As Gzip compresses the common strings, it reduces the file size up to 70%.
