miniz.c is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards.

Miniz is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply.

Features

  • MIT licensed
  • A portable, single source and header file library written in plain C
  • Tested with GCC, clang and Visual Studio.
  • Easily tuned and trimmed down by defines
  • A drop-in replacement for zlib's most used API's

See the miniz repository on GitHub

DATA_ERROR when reading zlib/miniz deflated data

I am writing a simple C++ wrapper for miniz-cpp's implementation of zlib compression. I got deflation to work, but now I have a problem with inflating the data again. Code I have a test case which (grossly simplified) boils down to: ByteArray…

compression level using miniz having no effect

I'm evaluating using the low-level routines in miniz and testing different compression levels with differently sized inputs. Level 0 always gets a little bit larger (as expected) but the other levels all result in the exact same size for the same…

What guarantees does zlib's inflate/deflate make about avail_in and avail_out?

What guarantees does zlib give on the state of avail_in an avail_out after a call to inflate? I am seeing peculiar behaviour with miniz that I want to make sure is not a misunderstanding of the zlib API. Effectively, after calling inflate, I have…
