Brunsli is a lossless JPEG repacking library.

Brunsli allows for a 22% decrease in file size while allowing the original JPEG to be recovered byte-by-byte.

It is possible to try how much Brunsli will save on your images on the site brunsli.dev. Images are transcoded in browser, no data is transmitted or stored. Codec is powered by WASM technology. Safari uses "interpretation" mode for WASM at first few runs after the page load. It is much slower. To avoid long wait, please feed codec with small images first.

Run the following commands to clone, configure and build Brunsli:

git clone --depth=1 https://github.com/google/brunsli.git
cd brunsli
git submodule update --init --recursive
cmake -DCMAKE_BUILD_TYPE=Release -B out
cmake --build out --config Release

For some platforms (e.g. Windows) libraries and executables are uploaded as "artifacts" as a part of continous integration process. Unfortunately, there is no static link to access those. Please follow the GitHub manual.
