This library adds ZIP compression functionality to your software.

The ZipArchive Library is written in C++ and offers the following features:

• Compression, decompression and modification of zip archives.
• Segmented archives support (splitting and spanning).
• Zip64 format^* - practically no limits for sizes and the number of files in archives.
• Unicode support^* in archives compatible with WinZip.
• AES encryption^* - in accordance with the WinZip format.
• Standard zip encryption.
• BZIP2 compression algorithm^* - provides a better compression ratio.
• ZSTD compression algorithm^* - fast lossless compression algorithm.
• In-memory archives processing.
• Progress notifications with controllable frequency of calling callbacks.
• Storing and retrieving custom data in extra fields.
• Possibility of bulk adding files using built-in or custom filters.
• Seeking in compressed data (with certain limitations)^*.
• Possibility to use zlib-ng instead of zlib.
• Easy API.
• Source code available.
• Comprehensive documentation with samples.
• Available in STL (cross-platform) and MFC (Windows) versions.
• Available for: Windows, Linux, macOS, iOS.
• Compiles under:
  CMake 3.25 and later, Microsoft Visual Studio 2017-2026 (possibly older as well), GCC, Clang, XCode, C++Builder .
• Hardware acceleration for AES and CRC32^*.
• Linux, macOS, Windows
• x64 (64-bit), x86 (32-bit), ARM64, and Universal binaries (macOS)
