Brotli Compression

A modern lossless compression algorithm developed by Google that achieves 15–25% better compression ratios than gzip for text-based web resources such as HTML, CSS, and JavaScript. Brotli is signaled via the Accept-Encoding: br request header and the Content-Encoding: br response header. It uses a predefined dictionary of common web content patterns, giving it an advantage over gzip for typical HTTP payloads without additional CPU cost at decompression time.
