Export & security

Encrypted file

The full vault in one .airhide file. It opens only with your passphrase.

Update it at every save

Encrypted text

The vault as text: paste it into any notes app or cloud service, or print it on paper. It stays unreadable without your passphrase.

Hide in an image

Embeds the encrypted vault in a PNG. Only your passphrase can locate it.

No carrier image selected

PNG images work best. Transparent pixels are skipped.

Update it at every save

Keep in this browser

A temporary copy of the encrypted vault, offered on the welcome screen of this browser.

Not a backup: the browser can delete it at any time (clearing site data, private browsing, low disk space, Safari after 7 days without a visit). Limit ≈ 5 MB per site: photos and videos fill it quickly. Anyone using this device can copy it and try passphrases offline, and it shows that Airhide is used here.

Update it at every saveWhile this vault stays open in this tab.

Readable export

Download the vault as a regular ZIP for use outside Airhide.
