A tiny macOS utility to convert archive files into ZST compressed .zst files — no setup, no clutter. ZSTify is a small, focused macOS utility for converting archive files into Zstandard (.zst) compressed files. Just drop one or more archive files (ZIP, 7Z, RAR, etc.) onto the app and ZSTify unpacks them and compresses the result to .zst or .tar.zst — quickly, locally, and without unnecessary options. Why ZSTify? Zstandard is a modern, fast compression format widely used in development, backups, and infrastructure. But if you receive or have archives in other formats (ZIP, 7Z, RAR…), macOS has no built-in way to convert them to .zst. ZSTify fills that gap with a clean, native experience. Features Drag & drop archives to convert to .zst or .tar.zst Open With → ZSTify or Finder Services → Convert to ZST Supports ZIP, 7Z, RAR, TAR, GZ, BZ2, XZ, LZ4 Option to convert nested archives inside folders to .zst too Output next to the originals Fast, streaming conversion (no unnecessary memory usage) Works fully offline - No background services, no setup - Designed for macOS - Minimal, distraction-free interface - Clear feedback after each conversion - Settings are remembered automatically = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - Part of The Beaver Tools — a collection of focused Mac utilities.
