## What it is
A small, portable zip archive library written in C, built on top of the miniz compression library. It provides a simple API for creating, appending to, and extracting zip archives from files or memory with just a few source files.

## Use cases
- create zip archives in C
- extract zip files to a folder
- compress files on-the-fly into a zip entry
- append entries to an existing zip archive
- extract a zip entry into memory
- embed a lightweight zip library in a mobile or embedded project

## When to choose
- you need a tiny, dependency-free zip library you can compile directly into a C/C++ project
- you want simple create/append/extract zip operations across OSX, Linux, Windows, Android, and iOS
- you dislike heavyweight compression frameworks and want a minimal API

## When to avoid
- you need advanced archive formats like tar, 7z, or encrypted zips
- you need streaming compression beyond zip or fine-grained control over deflate settings
- your project already uses a full-featured archive library like libarchive

## Facets
- artifact type: library
- maturity: active
- function: compression, file-system
- domain: files, developer-tools, cross-platform
- platform: windows, cross-platform, c
- tags: zip, miniz, lightweight, single-library, embedded-friendly, linux, macos, android, ios
