Website speed has become a critical factor for online success. A delay of just one second in page load time can result in a drop in conversions. That is why technologies like Brotli compression are essential tools for website owners looking to stay ahead with their site, providing a faster website to their visitors.
If you are hosting your site on xCloud, enabling Brotli compression could be one of the easiest ways to supercharge your website’s performance. Today, we will explore what Brotli compression is and how to enable Brotli in xCloud.Let us get started.
What Is Brotli Compression?
Brotli compression is an open-source, modern way to make files smaller, and it was created by Google in 2015. It was made to be better than older methods like Gzip Compression, giving smaller file sizes and helping websites load faster.
Compression means shrinking files so they take up less space when sent from a website to your browser. This makes pages load quicker without losing any data.
Brotli uses smart techniques like a built-in dictionary and Huffman coding to reduce file sizes more effectively than Gzip. It works especially well for web content like HTML, CSS, and JavaScript.
Brotli can make files up to 26% smaller than Gzip, which can significantly boost page speed, something both users and search engines like Google really appreciate.
While Gzip has been around a long time and is widely used, Brotli is now supported by most modern browsers like Chrome, Firefox, Safari, and Edge. That makes it a smart choice for developers who want faster websites.
With Brotli compression for faster websites, you will also benefit from smaller bandwidth consumption, which could mean cost savings if you pay for server bandwidth separately.
How Does Brotli Compression Work?
Brotli compression works by identifying repetitive patterns in files like HTML, CSS, and JavaScript. It then replaces those patterns with shorter representations using advanced algorithms. Brotli uses three main techniques:
- Modern LZ77 Algorithm: It finds repeated byte sequences and encodes them efficiently.
- Huffman Coding: It assigns shorter codes to more frequent bytes. This technique compresses data without losing any information.
- Second-Order Context Modeling: It predicts upcoming data based on previous byte patterns. This makes compression even smarter.
These techniques give Brotli a clear advantage over older methods like gzip. Brotli often compresses files 20% to 30% more efficiently, especially with text-based resources.
Brotli compression involves two main steps:
1. Compression on the Server
When a user requests a page, the server compresses web assets using the Brotli algorithm. This process reduces file sizes significantly without losing data.
2. Decompression in the Browser
Modern browsers recognize Brotli-encoded files. They automatically decompress the data in real time. This keeps the website fast and fully functional, with no visible delay for users.
Most Brotli tutorials mention that it supports compression levels ranging from 0 to 11. Lower levels compress quickly. Higher levels take more time but achieve better compression. Web servers usually choose a mid-to-high level to balance speed and performance.
Brotli also works exceptionally well with HTTPS. Although gzip supports secure connections too, Brotli was designed with HTTPS in mind. It delivers better performance under secure conditions.
Brotli excels at compressing text-based content such as:
- HTML
- CSS
- JavaScript
- JSON
- SVG
- Other text-like files
However, Brotli does not help much with binary files like images or videos. These files are usually already compressed.
A deeper understanding of how Brotli works reveals why many companies have switched from gzip. Brotli not only reduces file sizes, but also lowers CPU usage during decompression. This improves performance without straining user devices.
In short, Brotli compression is a powerful tool in modern web development. It creates smaller files, loads sites faster, and delivers a better user experience.
How to Enable Brotli Compression in the xCloud
If you host your website with xCloud, enabling Brotli compression is very simple. On xCloud’s new servers, Brotli comes pre-enabled for all eligible files served through NGINX. You do not need to configure anything manually unless you are using an older server setup.
To get the most out of Brotli, ensure your website uses HTTPS. Brotli only works over secure connections.
If your server uses Cloudflare (whether with NGINX or OpenLiteSpeed), you can enable Brotli in just a few clicks. Go to the Cloudflare dashboard, then navigate to ‘Speed’ and then ‘Optimization’ settings. Enable Brotli there to compress your assets efficiently without needing access to your server’s core settings.
With xCloud, Brotli compression is enabled by default so that your visitors always get smooth performance, and you do not have to go through the complex steps. For more details, check the detailed documentation to enable Brotli compression with xCloud.
Advantages of Using Brotli Compression
Now that you understand what Brotli compression is and how it works, let us look at why you should use it right away. The benefits of Brotli go far beyond just reducing file size. It can dramatically improve your website’s speed, user experience, and SEO performance.
1. Smaller File Sizes with Better Compression
Brotli delivers superior compression compared to older methods like gzip. It often reduces file sizes by 20% to 30% more, especially for HTML, CSS, JavaScript, and JSON files.
Smaller files mean browsers download less data. This leads to faster page loads and lower bounce rates. Faster websites also tend to rank higher in search results.
2. Faster Page Load Speeds
Web developers often enable Brotli to speed up page loads. When files are smaller, browsers can render pages more quickly. Users don’t have to wait, and your site feels instantly responsive.
This is not just about a better experience, it affects your bottom line. A one-second delay in load time can cause a 7% drop in conversions.
When applied correctly, Brotli can boost your Google PageSpeed Insights scores and improve your Core Web Vitals.
3. Improved SEO Performance
Google prioritizes fast, user-friendly websites. Brotli compression helps you meet that standard. Faster loading times improve user engagement, increase dwell time, and reduce bounce rates, all of which help your SEO rankings.
Google’s own tools check for modern compression. If you enable Brotli, you instantly meet an important technical SEO requirement.
Brotli is not just about saving bandwidth. It is also about gaining visibility in search engines.
4. Lower Bandwidth Usage
Smaller files mean less data transfer. If your site handles high traffic, Brotli can significantly reduce bandwidth costs.
This efficiency lowers your server load and can lead to savings on your hosting bills. Brotli’s performance offers both technical and financial benefits.
5. Better Performance on Mobile Devices
Mobile users often rely on slower connections. Every kilobyte counts. Brotli makes a big difference here by delivering lightweight assets that load faster on mobile networks.
By using Brotli, you optimize your site for mobile-first indexing, another major SEO factor. You also improve the experience for users on limited data plans.
How to Test Brotli Compression of Your Website
Before you enable Brotli on xCloud or confirm that it is working, you should first check if it is already active on your website. Verifying this is quick and easy, and it helps you ensure your site is optimized for speed, user experience, and SEO.
Use Online Tools
You can check the support for Brotli instantly with a number of free tools, such as:
- GiftOfSpeed Brotli Test: Enter your website URL. The tool checks if Brotli compression is active.
- KeyCDN Performance Test: Analyze your site’s compression method and overall performance.
- Google PageSpeed Insights: If Brotli is enabled, you will see confirmation under the “Compressed Transfer” recommendations.
Check in Browser Developer Tools
You can also verify Brotli directly in your browser by doing the following:
- Open your website in Google Chrome.
- Right-click anywhere on the page and select Inspect.
- Go to the Network tab.
- Reload the page.
- Click the main request (usually your homepage URL).
- Look under the Headers section for Content-Encoding.
If you see ‘br’, Brotli compression is active. If you see gzip instead, Brotli is not enabled yet. In that case, check your server settings, especially if you are using xCloud.
3. Use the Command Line
If you are comfortable with the terminal, try this:
curl -s -I -H “Accept-Encoding: br” https://example.com | grep -i “content-encoding”
If the response shows Content-Encoding: br, your website uses Brotli compression.
