GZIP compression checker is an online Free SEO Tool used to check if GZIP compression on a web server is enabled or not.
By having this tools enabled, you can save up between 50% - 80% of your bandwidth, which will therefore increase significantly, the loading speed of your web site.
GZIP compression makes it possible to compress your web files (mainly HTML, CSS, and JS files), sometimes up to 80%. This much smaller compressed version of the file is then sent to the browser of the visitor instead of the larger original file. The browser of your visitor will then automatically decompress the compressed file and serve the uncompressed original file to your visitor.
