File Armor: Encrypt Files Locally in Your Browser
Encrypt a PDF, photo, or document with a password, entirely offline in your browser. Lock or unlock files with a custom passphrase: encryption and decryption happen instantly on your device, with nothing ever uploaded.
Frequently asked questions
Does my file get uploaded anywhere?
No. The file never leaves your device: encryption and decryption happen entirely in your browser using the Web Crypto API. Notenz's servers never see the file or your passphrase.
What encryption does File Armor use?
AES-256-GCM, the same standard used by password managers and full-disk encryption tools. The encrypted file can only be opened with the exact passphrase you set.
What if I forget the passphrase?
There's no recovery, Notenz never stores it. For passphrases you might forget, consider keeping a hint in your Notenz vault, delivered to a trusted contact if you ever go silent. See Notenz's free vault.
