Brotli is a lossless data compression algorithm developed by Jyrki Alakuijala and Zoltán Szabadka. It uses a combination of the general-purpose LZ77 lossless compression algorithm, Huffman coding and 2nd-order context modelling. Brotli is primarily used by web servers and content delivery networks to compress HTTP content, making internet websites load faster. As successor to gzip, it is supported by all major web browsers and has become increasingly popular, as it provides better compression than gzip.
