This post shows students and new users how to add Brotli support to Apache when using Ubuntu Linux. Brotli is an open-source compression algorithm developed by Google that can be used as an alternative to Gzip, Zopfli, and Deflate. In some studies, data can be compressed by 10 to 20 percent more than current compression algorithms.
If you want to use Brotli with Apache, you’ll have to enable the use Apache brotli module. Unlike Nginx, there’s full Brotli support for the Apache web servers.
This post was tested on Ubuntu Linux but should apply to other Linux distributions. I selected Ubuntu because it’s easy to use, especially for new users.
Also, for students and new users learning Linux, Ubuntu Linux is the easiest place to start learning. Ubuntu is the modern, open-source Linux operating system for desktops, servers, and other devices.
When you’re ready to include Brotli support with Apache, follow the steps below:
How to install Let’s Encrypt SSL on Ubuntu Linux
Brotli requires SSL. Apache will need to have SSL support before you’ll be able to use Brotli. Since Let’s Encrypt is easy to install and use with Ubuntu, we’ve written a great post on installing a Let’s Encrypt free SSL certificate.

How to Install Apache on Ubuntu Linux
If you haven’t already installed an Apache server, use the steps below to download and install it from the Ubuntu repository.
Installing Apache on Ubuntu Linux is pretty straightforward. Apache package is in Ubuntu repositories, so all one needs to do is run the apt-get command to install it.

How to install and enable the Apache Brotli module
At this point, you should have Apache installed with Let’s Encrypt support. If you haven’t already done so, refer to the steps above.
Before enabling the Brotli module for Apache, you must first install it. Brotli package is available in the Ubuntu default repository.
Simply run the commands below to install Brotli.
sudo apt install brotli
Once Brotli is installed, run the commands below to enable the Apache Brotli module.
sudo a2enmod brotli
Next, add the directive to Apache virtual host to enable Brotli support. You need to add the below code in the virtual host configuration file.
<IfModule mod_brotli.c>
AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>
An example example.com.conf virtual host configurations should look similar to the one below.
<VirtualHost *:80>
ServerAdmin admin@example.com
ServerName example.com
DocumentRoot /var/www/
<IfModule mod_brotli.c>
AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
When you add Brotli support above, run the commands below to restart Apache.
sudo systemctl restart apache2
You can text Brotli support using the curl command against your domain.
curl -I -H 'Accept-Encoding: br' http://example.com
That should do it!
Conclusion:
- Brotli is an efficient compression algorithm that can significantly enhance website performance by reducing data transfer sizes.
- By following the steps outlined above, you can easily enable Brotli support on your Apache server running Ubuntu Linux.
- Ensuring you have Let’s Encrypt SSL installed is crucial for utilizing Brotli, as it requires SSL support.
- Regularly verify and test your server’s compression capabilities to ensure optimal performance.
- For an increased visitor experience, consider monitoring your website’s load time and responsiveness after enabling Brotli compression.
