'' 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.
|
|
|
|
The specification of the Brotli Compressed Data Format is defined
|
|
in the following internet draft:
