## What it is
Miniz is a lossless data compression library in a single C source file implementing the zlib (RFC 1950) and Deflate (RFC 1951) formats as a drop-in zlib replacement under the MIT license. It also includes APIs for reading/writing ZIP archives and writing PNG image files.

## Use cases
- replace zlib without its licensing requirements
- add deflate compression to a C/C++ project with a single source file
- read and write ZIP archives in embedded or game development
- compress data in real time comparable to fastlz or minilzo
- write PNG image files from C code
- embed a portable compression library in mobile or console apps

## When to choose
- you need zlib-compatible compression with a permissive MIT license
- you want a single-file, dependency-free C library that's easy to embed
- you need lightweight ZIP archive manipulation in C
- you target embedded, mobile, or game platforms where portability matters

## When to avoid
- you need multithreaded or SIMD-optimized compression performance
- you need advanced zlib features or full API compatibility
- you need modern compression formats like zstd or brotli
- you need a full-featured archiver rather than basic ZIP APIs

## Facets
- artifact type: library
- maturity: stable
- function: compression
- domain: files, developer-tools, cross-platform
- platform: cross-platform, cpp, c
- tags: zlib-replacement, deflate, zip, png, single-file, embedded
