Frequently asked questions about ZipVault.
Getting Started
How do I create an archive?
Drag files or folders onto the drop zone, or click Choose to select items. Adjust compression and password settings on the right, then click Create Zip Archive.
How do I choose where archives are saved?
Click the output location area at the bottom of the window to pick a folder. ZipVault remembers your choice between sessions using a security-scoped bookmark.
Passwords & Security
How does password protection work?
Toggle Password setting on, enter a password and confirm it. The archive will be encrypted so that extracting any file requires the password.
What is AES-256 vs Legacy Compatibility Mode?
AES-256 (default) uses strong, modern encryption. Enable Compatibility Mode to use legacy PKWARE encryption, which is weaker but compatible with older tools that don't support AES.
How does Keychain storage work?
When Store password is enabled, ZipVault saves the archive password
in your macOS Keychain. It is stored with
WhenUnlockedThisDeviceOnly accessibility —
device-local, never synced.
Can I reveal a stored password?
Yes. Open History, select an archive, and tap the reveal button. You'll be prompted for device-owner authentication (Touch ID or password) before the password is shown.
Archives
What does 'Check archive' do?
When enabled, ZipVault reads the archive after creation to verify its ZIP structure (end-of-central-directory record, central directory entries) and confirms whether password protection was applied correctly.
What compression levels are available?
The compression dial maps to ZIP levels 0 through 9. Level 0 stores files with no compression (fastest). Level 9 applies maximum compression (smallest file size). The default is level 5 ("Normal").
Purchases
What's included in the free version?
The free tier lets you create archives up to 100 MB with all features (compression, encryption, validation, history).
What does the unlock purchase include?
The one-time Unlimited Archives purchase removes the 100 MB size limit. All other features are the same — there is no subscription.
