libzip is a C library for reading, creating, and modifying zip archives, with support for Zip64, multiple compression codecs (deflate, bzip2, LZMA, zstd), and Winzip AES/PKWARE encryption. It ships with command-line tools (ziptool, zipcmp, zipmerge) and has bindings for Python, Ruby, Lua, and PHP.
Use cases
- read and extract zip archives in a C or C++ application
- create zip files programmatically with compression
- modify existing zip archives without corrupting them
- handle encrypted zip archives with AES or PKWARE encryption
- work with large zip64 archives
- compare or merge zip archives from the command line
When to choose
- you need a mature, stable C library for zip manipulation with a backwards-compatible API
- you need encryption, Zip64, or multiple compression algorithm support
- you want a small, efficient library usable in commercial products under a BSD license
- you need cross-platform support across Linux, macOS, and Windows
When to avoid
- you need to handle archive formats other than zip, like tar or 7z
- you are working in a language with a native zip library and don't want a C dependency
- you need a high-level object-oriented API rather than a C API
