A tiny macOS utility to compress files and folders into a single .zst file — no setup, no clutter.
PackZST is a small, focused macOS utility for creating Zstandard (.zst) compressed files.
Just drop one or more files or folders onto the app and PackZST compresses them to .zst (or .tar.zst) — quickly, locally, and without unnecessary options.
Why PackZST?
Zstandard is a modern, fast compression format widely used in development, backups, and infrastructure — but macOS has no built-in way to create .zst files.
PackZST fills that gap with a clean, native experience.
Features
- Drag & drop files to compress as .zst
- Drag & drop folders to create .tar.zst archives
- Select compression mode (Fast, Balanced, Smallest)
- Packs files next to the originals
Fast, streaming compression (no unnecessary memory usage)
- Works fully offline
- No background services, no setup
- Designed for macOS
- Minimal, distraction-free interface
- Clear feedback after each compression
- Settings are remembered automatically
- = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = -
