Stow: Zip, Unzip & Archive

Stow is a private, on-device archiver for Mac, iPhone, and iPad. Pack files, unpack downloads, and keep control of where every result goes.

Powerful on Mac

- Drop files and folders to create an archive.
- Open archives and browse their contents before extracting.
- Preview files and extract only the items you need.
- Add files to an existing archive without risking the original.
- Work directly from Finder with contextual compression and extraction actions.
- Follow queued work with progress, time estimates, pause, and cancel controls.
- Limit archive expansion and item counts to reduce the risk from zip bombs.
- Verify archives and create checksum sidecars.
- Split large archives into smaller volumes.

Flexible formats

Create ZIP, 7-Zip, TAR, TAR.GZ, TAR.BZ2, TAR.XZ, TAR.ZST, GZIP, BZIP2, XZ, Zstandard, LZ4, and Lzip archives. Open those formats plus RAR, ISO, CAB, CPIO, Unix Compress, LZOP, LRZIP, GRZIP, and common split archives.

Safer encryption

Stow uses AES-256 for encrypted ZIP archives and supports encrypted 7-Zip archives, including encrypted filenames. Passwords can stay in your Keychain instead of being stored in project files or sent over the network.

Focused on iPhone and iPad

Choose files from the Files app, pack them into a new archive, or unpack an archive into Stow's local folder. Mobile includes the formats and controls needed for everyday file workflows without pretending to duplicate every desktop feature.

Private by design

Archive work happens on your device. Stow has no accounts, analytics, advertising, or data collection.
