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 RFC 7932.

Build instructions

Autotools-style CMake

configure-cmake is an autotools-style configure script for CMake-based projects (not supported on Windows).

The basic commands to build, test and install brotli are:

$ mkdir out && cd out
$ ../configure-cmake
$ make
$ make test
$ make install

By default, debug binaries are built. To generate “release” Makefile specify --disable-debug option to configure-cmake.


See Bazel


The basic commands to build and install brotli are:

$ mkdir out && cd out
$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed ..
$ cmake --build . --config Release --target install

You can use other CMake configuration.


See Premake5


To install the latest release of the Python module, run the following:

$ pip install brotli

To install the tip-of-the-tree version, run:

$ pip install --upgrade git+

See the Python readme for more details on installing from source, development, and testing.
