Online Brotli test - Verify if your server or CDN supports Google's Brotli compression algorithm.
Brotli is a new open source compression algorithim developed by Google as an alternative to Gzip, Zopfli, and Deflate. Google's case study on Brotli has shown compression ratios of up to 26% smaller than current methods, with less CPU usage.
With our tool you can quickly check if your web server is sending the Brotli compressed payload to your clients. Negotiation is done via the
Accept-Encoding: br request header. Servers can add "br" to
Content-Encoding: br to encode a response with Brotli.
Both the server and the client (browser) must be Brotli compatible to take advantage of smaller file sizes and be running over an HTTPS connection. Brotli compression is currently supported by the following browsers:
