Zstandard is fast, modern, and efficient.
But on Mac, .zst files are still not as familiar as ZIP.
You download a server backup.
You receive a compressed export.
You move build artifacts between machines.
You archive project folders.
You want better compression without waiting forever.
That is where unpackZST comes in.
unpackZST is a small collection of Mac tools for working with Zstandard files — focused, local, and built for practical archive workflows.
Fast archive workflows on Mac
The idea is simple:
Use the right small tool for the ZST job in front of you.
Need to open a .zst file? Use unpackZST.
Need to convert older archives into .zst? Use ZSTify.
Need to unpack many archive formats? Use unpackALL.
Need a simple workflow without Terminal commands? Use the Mac app.
No giant archive manager.
No cloud upload.
No command-line flags just to get files in or out.
Just archive in, result out.
Local by design
Archives often contain private material: projects, backups, documents, logs, exports, client files, or source code.
That is why local workflows matter.
The tools on unpackZST are made for working directly on your Mac, without sending files to an online extractor or converter.
