A tiny macOS utility to extract .zst and .tar.zst files — no setup, no clutter.
unpackZST is a small, focused macOS utility for extracting Zstandard (.zst) compressed files.
Just drop one or more .zst files onto the app and unZST takes care of the rest — quickly, locally, and without unnecessary options.
Why unZST?
Zstandard is a modern, fast compression format widely used in development, backups, and infrastructure — but macOS has no built-in way to open .zst files.
unZST fills that gap with a clean, native experience.
Features
- Drag & drop .zst files to extract
- Optional automatic extraction of .tar.zst archives
- Optional deletion of .tar files after extraction
Fast, streaming decompression (no unnecessary memory usage)
- Works fully offline
- No background services, no setup
- Designed for macOS
- Minimal, distraction-free interface
- Clear feedback after each extraction
- Settings are remembered automatically
- = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = -
