Check and Enable GZIP compression

This handy tool checks if you have GZIP compression enabled, and makes it possible to turn on GZIP compression.

What is GZIP compression?

GZIP compression is bundling (zipping) pages on a web server before the page is sent to the visitor. This saves bandwidth and therefore increases the loading speed of the page significantly. The visitors' web browser then automatically unzips the pages. This compressing and unzipping only takes a fraction of a second.

GZIP compression is recommended for all types of text files such as: - HTML (.html) but also all types of dynamic HTML (such as extension .php, .aspx) - Textfiles (extension .txt) - CSS and Javascript (extensie .css and .js) - Webservices, such as WSDL, REST and JSON

GZIP compression is not recommended for non-text files, such as graphical files and .zip files because it hardly saves space and can therefore increase the loading time.

Why is GZIP compression important?

GZIP compression saves 50% to 80% bandwidth and will therefore significantly increase the website's loading speed. The textfiles are compressed (zipped) on the web server after which the visitor's web browser will automatically unzip the files. This compressing and unzipping only takes a fraction of a second without the end user noticing.

Just about all the large websites worldwide use GZIP compression. For and actual overview of GZIP usage nowadays please check our statistics page.
