Brotli Checker

What is a Brotli Checker Tool?

A Brotli Checker Tool is an online or command-line tool that helps you check if a website or web server is using Brotli compression for delivering compressed content, such as text, JavaScript, CSS, and HTML. Brotli is a modern compression algorithm developed by Google, and it is known for providing better compression rates than older methods like Gzip or Deflate.

How Brotli Checker Works

1. Request to Website

   • The tool sends a request to a website or server asking for a specific resource (like a webpage or JavaScript file).

2. Checking for Brotli Compression

   • The server responds with the requested file, and the tool checks if the Content-Encoding: br header is present in the HTTP response.
   • If the header is present, it means the resource is compressed using Brotli. If it's not, the server may be using Gzip or Deflate, or no compression at all.

3. Displaying Results

   • The tool will indicate whether Brotli compression is enabled for that resource or website, along with any relevant headers or other compression details.

Why Use a Brotli Checker Tool?

1. Check Compression Optimization

   • Brotli offers better compression than Gzip, resulting in smaller file sizes and faster page load times. By using a Brotli checker, you can verify if a website is benefiting from Brotli compression.

2. Improve Website Performance

   • Ensuring Brotli is enabled can improve website speed, especially for mobile users, as it reduces the time it takes to load resources like images, CSS, and JavaScript files.

3. SEO Benefits

   • Faster page load times can enhance SEO rankings, as Google uses page speed as a ranking factor.

4. Check Server Configuration

   • If Brotli compression is not enabled, this tool can help identify server misconfigurations or missing compression settings, allowing webmasters to make improvements.

How to Enable Brotli Compression on a Server?

1. For Nginx:

   • Install Brotli module:
     sudo apt-get install brotli

      
   • Enable Brotli in the Nginx configuration:
     http { brotlion; brotli_comp_level6; brotli_staticon; }

      
   • Restart the Nginx server:
     sudo systemctl restart nginx

2. For Apache:

   • Install Brotli module for Apache:
     sudo a2enmod brotli

      
   • Enable Brotli compression in Apache's configuration:
     AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/css application/javascript application/json

      
   • Restart Apache:
     sudo systemctl restart apache2
