GZIP compression reduces the size of web files by compressing them. GZIP compression is becoming more important as a quality factor for Google, as many sites use it to upload compressed versions of files to web hosting servers. You can restore the original data from a compressed file by unzipping it. The GZIP compression is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding.
GZIP can handle many different file formats, including ones that other compression programs can't.
.gz – denotes the file extension of GZIP files.
.tar– A form used to store various archive files, not to compress data. You can use GZIP to shrink .tar files.
.tgz, .tar.gz, .gz file – GZIP file can compress all these file formats efficiently.
Today's websites are full of visual, graphic, audio, textual, and video content. If the files you're loading aren't in a compressed format, It becomes difficult for the browsers to load them. Compression algorithms are often compared, such as GNU, GZIP, 7-ZIP, and zopfli. These implementations are typically compared to see which is the best option. Modern browsers can decompress files when asked so that users can see them more easily.
There are two ways to make your website load faster:
Eliminate all unwanted resources.
Compress all the wanted resources.
Enabling GZIP compression on your web server can help you improve web performance. Nowadays, all modern browsers support the GZIP compression format.
A compression algorithm takes a set of data and reduces its size without losing any information. The raw data could be any type of file. However, GZIP is best for text-based assets, like HTML, CSS, and JS.
How to enable GZIP compression?
Setting up file compression for your website will depend on the type of server you're using. GZIP compression can reduce the size of your web file by up to 50%, which may make sending it to the server faster and more efficient. Therefore, setting up compression on your website isn't difficult, you can start with simple and necessary steps.
First, if you're using Apache, you can activate GZIP compression by visiting the module mod-deflate and adjusting the settings. Second, if you are using IIS, you can configure compression settings through the IIS Manager interface or via the command line. It is always a good idea to make a backup of your server settings before making any changes.
Finally, to test whether your website is using GZIP compression, you can use our GZIP compression tester. To determine if a website is connected to the Internet, use the Domain Name System (DNS). If you have not connected the website to the Internet, you can fix the error by manually entering the website's IP address.
