7‑Zip vs PeaZip
Side-by-side comparison of features, pricing, ratings, and alternatives.
7‑Zip is a free, open‑source file compression utility that supports a wide range of archive formats. It offers a high compression ratio for its native 7z format and can handle ZIP, RAR, TAR, GZIP, and many others. The program integrates with Windows Explorer for easy right‑click operations and provides a powerful command‑line interface for scripting and automation. It runs on Windows, Linux, and macOS, making it a versatile tool for developers and power users alike.
PeaZip is a free and open-source file archiving utility that can open and extract over 200 archive formats, including ZIP, RAR, 7Z, TAR, and GZ, and create archives in its own formats plus common ones like ZIP and 7Z. It ships as a portable, no-install option as well as a standard installer across Windows, Linux, macOS, and BSD. Beyond basic compression, PeaZip includes AES-256 encryption with optional two-factor authentication for password-protected archives, secure file deletion, checksum/hash verification, and archive splitting and joining for large files. Its GUI wraps several open-source compression backends (7-Zip, FreeArc, PAQ, and others) behind a single consistent interface, and it is licensed under LGPLv3.
