What is GZIP

GZIP is a common type of data compression that takes a large quantity of data and compresses it. The original data can also be recovered by unzipping a compressed file.

What is GZIP Compression?

GZIP is a file format and program that is used to compress HTTP content before sending it to a client. The procedure allows for a 50% reduction in data size. Due to this GZIP compression, the page load time will be accelerated, and bandwidth use will be reduced.

Many file types are supported by GZIP, including:

  • .gz – denotes the file extension of GZIP files.
  • .tar– A form used to store various archive files, not to compress data. GZIP can be used to shrink .tar files.

Along with that, it will also provide you with some further details, such as the file size of the original version of the website you tested and the potential benefits of employing Gzip compression.

Websites are now overrun with visual, graphic, audio, textual, and video information. If the files are not in compressed format, it becomes difficult for the browsers to load the material in a matter of seconds.

What does Gzip compression checker do?

Gzip compression is a process that makes web files (mostly HTML, CSS, and JavaScript files) smaller, sometimes by up to 70%–80%. The person requesting the file then receives this considerably smaller compressed version of the file rather than the bigger original file in their browser. After that, the user's browser will automatically decompress the compressed file and deliver the original, uncompressed file.

You may believe that GZIP compression is the de-facto compression technique for compressing text data on web pages. It is also important to be aware that GZIP offers excellent speed and compression ratio control and is a lossless compression method.

GZIP compression is based on the internals of the DEFLATE algorithm, which is a mix of LZ77 and Huffman coding.

Different implementations of data compression, including GNU, GZIP, 7-ZIP, and zopfli, will be compared primarily with an emphasis on how one performs better than the others. Facts show that users typically choose GZIP data compression because of its outstanding lossless data compression capabilities.

How Can GZIP Compression Be Enabled On Your Website Server?

With GZIP Compression, you may reduce the size of your web file (PHP, CSS, JS, HTML) by up to 50%, allowing you to transmit it to the server more quickly and effectively. The file can then be sent back to the user's browser from the server after being decompressed to its original size. There is no need to upload huge web files to the server since GZIP Compression may quickly reduce the size of your data.

Using mod-deflate or mod-zip, you may enable GZIP compression on your web server. Professional programmers are likely aware that the deflate approach has greater benefits than mod-zip since it compresses the output from your server before it is transmitted to the user's browser. Additionally, this technique is easier to configure and has better documentation. Mod-deflate is also more often supported than mod-zip. If mod-deflate does not function on your host, you can, without delay, switch to mod-zip.

It's important to note that not every host has enabled these modules on their servers. Therefore, if they provided .htaccess scripts don't function, so you might need to contact your host. By clicking on the linked link, you may obtain the code for mod-zip and mod-deflate.

What is Brotli?

An open-source data compression algorithm is called Brotli. It is often a superior compression method to Gzip since it can typically compress data to a smaller size than Gzip can. In comparison to Gzip, Brotli also decompresses files more quickly.

Is it better to use Brotli instead of Gzip?

All of the major browsers currently offer support for Brotli. However, not all of them do. If you wish to utilize Brotli, you may set up your server to alternate between Brotli and Gzip based on the visitor's browser. Soon, we will have more to say about that!


What is GZIP compression, and why is it important for SEO?

GZIP compression is a method for reducing the size of web page assets like HTML, CSS, JavaScript, and images. It makes pages faster to load. Faster page speeds improve user experience and are a positive ranking factor for SEO.

How can I check if a page has GZIP enabled?

Are there any downsides to using GZIP?

The main downside is it adds a small amount of CPU usage on the server for compression. But the speed benefits usually outweigh the minimal processing costs.
