Compressing your content saves bandwidth and improves render time, particular on devices with slow internet connections. But it also reduces load on your server. While it does take some amount of computer power to compress files on the fly, you save much more power by having your server doing fewer things at once. It takes a lot less time to transfer files that are smaller. Your server is therefor, at any given time, maintaining far fewer open connections. There really is no down-side to enabling some form of HTTP compression.

The best way to enable this compression, is by using mod_deflate or modgzip. You can use them to automatically compress all HTML, CSS, JavaScript and XML content. And even SVG images, which are a form of xml. If your server is not configured to compress content, and you are unable to change that, there is an alternative. It only applies to HTML, but you can add one simple line of PHP to the top of your documents, to let PHP gzip the HTML on the fly.

GZIP is a generic compressor that can be applied to any stream of bytes: under the hood it remembers some of the previously seen content and attempts to find and replace duplicate data fragments in an efficient way - for the curious, great low-level explanation of GZIP. However, in practice, GZIP performs best on text-based content, often achieving compression rates of as high as 70-90% for larger files, whereas running GZIP on assets that are already compressed via alternative algorithms (e.g. most image formats) yields little to no improvement.

All modern browsers support and automatically negotiate GZIP compression for all HTTP requests: our job is to ensure that the server is properly configured to serve the compressed resource when requested by the client.

I hope the above explanation is enough if you need further explanation let me know…!!!
