Brotli is a new compression algorith developed by Google. The smaller compressed response sizes allows for better space utilization and faster page loads. Brotli is able to outperform gzip in many situations. Current browser support is listed here. IIS Brotli automatically applies Brotli compression to IIS responses when applicable.


Brotli offers up to 20-30% size reduction compared to gzip responses
