Encrypt files. Keep the key.

Zero-knowledge encryption in your browser. No account required for local encryption — your files never touch our servers unencrypted.

Sign in or register to store files in the cloud.

Drag & drop files or browse — multiple allowed

Minimum for encrypt/upload: 12+ characters, not a common password, and Strong or Very Strong.

How it works

1

Choose a file & passphrase

Pick any file up to 100 MB. Enter a strong passphrase only you know.

2

Encrypt in your browser

AES-256-GCM encryption happens entirely in your browser using the Web Crypto API.

3

Download or share

Save the encrypted file locally, or generate a time-limited share link.
