About this Brotli Test Tool

We’ve built this tool to help you to verify if your webserver supports & is configured to send Brotli compressed data to the browser. We check the web server headers in order to find out if Accept-Encoding: br is present on the request we made.

What is Brotli compression?

Google’s Brotli is the new replacement for the old gzip and deflate compression. It is a revolutionary open source compression algorythm created by Google engineers. A Brotli study conducted by Gooogle confirmed that it can help to achieve up to 25% more compression ration for files than traditional gzip/deflate methods. It also uses less CPU, which helps to reduce server load significantly.

What Browsers do support Brotli?

In order to work, Brotli must be compatible from both sides: server and client (browser). Let’s suppose you already installed brotli compression on your server, now it is very useful to know which browsers are brotli compatible.
