Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
ngx_brotli is a set of two nginx modules:
- ngx_brotli filter module – used to compress responses on-the-fly,
- ngx_brotli static module – used to serve pre-compressed files.
