File Encryptor

Encrypt any file with AES-256 and a passphrase - fully in your browser.

How to use

  1. Drop in the file you want to protect.
  2. Set a strong passphrase (and confirm it).
  3. Download the encrypted .enc file - share it and the passphrase separately.

Frequently asked questions

How strong is the encryption?

AES-256-GCM with a key derived from your passphrase via PBKDF2 (310,000 iterations) - the same primitives banks and password managers use.

What if I forget the passphrase?

The data is unrecoverable - there's no backdoor and we never see your key. Store the passphrase in a password manager.

Is the file uploaded?

Never. Encryption runs in your browser via the Web Crypto API - the file and passphrase stay on your device.
