Pack7Z is a small, focused macOS utility for creating 7Zandard (.7Z) compressed files.
Just drop one or more files or folders onto the app and Pack7Z compresses them to .7Z (or .tar.7Z) — quickly, locally, and without unnecessary options.
Why Pack7Z?
7Zandard is a modern, fast compression format widely used in development, backups, and infrastructure — but macOS has no built-in way to create .7Z files.
Pack7Z fills that gap with a clean, native experience.
