Boost Your Website Speed with Gzip and Brotli Compression

When it comes to improving your website’s loading speed, compression technologies like Gzip and Brotli play a vital role. This article explains how these compression methods work, their benefits, and how you can enable them to boost your website’s performance.


How Does the Compression Test Work?

The compression test checks if your website has Gzip or Brotli compression enabled by connecting to your domain and requesting the relevant data. In addition to revealing whether compression is active, the test also provides valuable insights such as the original file size of your web pages and how much you could benefit from using Gzip compression.


What is Gzip Compression and How Does It Help?

Gzip is a widely used compression algorithm that reduces the size of web files, particularly HTML, CSS, and JavaScript. By compressing these files, Gzip can shrink them by up to 70%-80%, making the web pages significantly smaller in size. The compressed files are then sent to the browser, which automatically decompresses them and serves the original uncompressed files to the user.

This results in a faster loading time for your website because smaller files require less time to transfer over the network.


The Impact of Gzip/Brotli on Your Website’s Speed

When you enable Gzip or Brotli, the files being served by your website become smaller, which in turn reduces the amount of data that needs to be transferred to load your pages. This leads to faster loading times and improved user experience.

In fact, by analyzing the waterfall chart in our page speed test, you can see how each file on your website is being compressed and the corresponding impact on the load time. The more files that are compressed, the faster your site will load.


How Do I Enable Gzip on My Website?

Enabling Gzip is a straightforward process. You can find detailed instructions and more information on how to enable Gzip on your website by following our step-by-step guide [here].


What is Brotli and Why Is It Better Than Gzip?

Brotli is an open-source data compression algorithm developed by Google. Compared to Gzip, Brotli usually compresses files to a smaller size, which makes it a more efficient choice for website compression. In addition to better compression, Brotli also has a faster decompression speed, allowing for quicker loading times.


Should You Use Brotli Instead of Gzip?

While Brotli offers better compression rates, it’s important to note that not all browsers currently support it. However, most major browsers now do, meaning it’s a good option to consider. To maximize compatibility, you can configure your server to automatically switch between Gzip and Brotli depending on the browser your visitors are using. Stay tuned for more updates on this as Brotli support continues to grow.
