zopflipng – PNG optimisation tool using zopfli

Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression.

The basic function to compress data is ZopfliCompress in zopfli.h. Use the ZopfliOptions object to set parameters that affect the speed and compression. Use the ZopfliInitOptions function to place the default values in the ZopfliOptions first.

ZopfliCompress supports deflate, gzip and zlib output format with a parameter. To support only one individual format, you can instead use ZopfliDeflate in deflate.h, ZopfliZlibCompress in zlib_container.h or ZopfliGzipCompress in gzip_container.h.

This is free and open source software.
