DiskPress combines native file compression and APFS file deduplication to help you make better use of the disk you already have — without deleting anything.
Key Features
- Lossless File Compression — Stores supported files using fewer bytes while preserving their full original contents. macOS reads compressed data automatically, so files open in the apps you already use.
- File Deduplication — Identical files share physical storage. Eligible duplicates can share compressed data for even more savings.
- Menu Bar Integration — Check available space, current measured savings, and recent savings (24h, 7d, 30d) directly from the menu bar. Add locations, optimize now, open settings, or stop monitoring with one click.
- Background Monitoring — Enable automatic monitoring to revisit chosen locations on a schedule. After the first pass, compression focuses on new or modified files.
- Full CLI — Inspect targets, optimize files, and read settings and savings with structured JSON output. No open window required.
- Built for APFS — Entirely on your Mac. Your files and optimization results stay local. Works offline.
DiskPress requires macOS 10.15 or later.
