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.
Keka is a native macOS file archiving utility built around drag-and-drop simplicity. Users drop files or folders onto the Keka window or dock icon to compress them into 7z, ZIP, TAR, DMG, ISO, and other formats, with optional AES-256 password encryption for sensitive data. It can also split large archives into smaller chunks for easier transfer or storage on removable media. On the extraction side, Keka handles more than 30 archive formats including RAR, WIM, and APK, so Mac users are not limited to whatever format a file happened to arrive in. The app is distributed free directly from the developer's website, with an optional paid copy available on the Mac App Store as a way to support development, and its core engine is open source on GitHub.
