What is gzip Compression?

When a user visit your website a request is made to web server to deliver the requested data. The response of the server is directly proportional to the size in mb/kb of the page as generally all pages contains video, images and textual part. so as page size bigger response time will be higher
Gzip facilitate to compress the your webpages  video, image and textual and style sheets before serving the request them over to the browser. This really reduces response time since the files are now in less size due to compression.
Gzip is the technique right now most effecting in the all speed optimization concept

First of all you need to have a “.htaccess” file, If not create it and edit with the following code.

<IfModule mod_deflate.c>
  # Compress HTML, CSS, JavaScript, Text, XML and fonts
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf

  BrowserMatch ^Mozilla/4\.0[678] no-gzip
  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
  Header append Vary User-Agent
</IfModule>


After Applying the code to the htaccess test the website url with a http://checkgzipcompression.com/.
