iPhone
Count down to important dates right from home screen widgets. Core features work offline, no account required.
Got an archive you can't open? ZipChest opens it in one tap.
ZipChest is a clean archive tool, and **every feature is open to everyone**. Unzip as much as you like — unlimited files, unlimited size, encrypted archives included, files on iCloud or any mounted cloud drive included. Packing, encrypting and choosing a format work the same way. No subscription, no countdown timers, no "you've used your two tries".
UNZIP
- Opens zip (including password-protected and ZIP64 archives), 7z (including AES-256 encrypted), tar, tar.gz, tar.bz2, tar.xz, gz, bz2, xz, and iso disc images
- Legacy non-UTF-8 file names decode correctly
- Open archives right from Files, Mail, or any app's share sheet
- Browse before extracting: see the file tree and sizes, tap any file for an instant preview
- Extract everything with one tap, or select just the entries you need
- Extract next to the archive, or pick any destination — including cloud drives mounted in Files
- Live progress with cancel; malicious paths are blocked and cancelled jobs leave no half-written files
PACK
- Select files and folders, pack them into a zip — no limit on how many
- **AES-256 encrypted zips** — password-protect contracts and photo packs
- **7z output**
- **Compression level 1–9**
- All of the above are included. No purchase required.
ABOUT ADS
ZipChest is funded by a single banner at the bottom of the screen. If it gets in your way, the "Remove Ads" purchase takes it away for good — **it does not unlock any features, because every feature is already available**. Restore Purchases brings it back on a new device.
PRIVACY
Compression, extraction and encryption all happen on your device; your files are never uploaded to any server, and passwords live in memory only and are never stored. The app works normally in airplane mode — **only the banner at the bottom needs a connection**. ZipChest does not track you and never shows the "Allow tracking" prompt.
Supported formats (this version): zip (plain/encrypted/ZIP64), 7z (plain/encrypted), tar, tar.gz, tar.bz2, tar.xz, gz, bz2, xz, iso. More formats are on the way.
