No tracking cookies

We don't profile or collect personal data—just the minimum to run the service.

Auto-delete by design

Encrypted files are removed right after sending; keys are not stored on our servers.

How It Works

Sending an encrypted file takes less than a minute — no account needed.

1

Pick a file & two emails

Choose any file up to 10 MB and enter the recipient's email plus a second email for the key. Your browser encrypts the file with AES-256 before upload.

2

We deliver file & key separately

The encrypted file and the decryption key are sent in two separate emails, so intercepting one alone reveals nothing.

3

Recipient decrypts locally

The recipient uploads the file on the decrypt page, pastes the key, and the original file is restored entirely in their browser.

Frequently Asked Questions

Yes. You can send files up to 10 MB, two files per hour, completely free. There is no registration, no account, and no hidden cost.

No. Files are encrypted with AES-256-GCM in your browser before they are uploaded. Our servers only ever see the encrypted version, and the decryption key is never stored on our side.

The recipient gets two emails: one with the encrypted file and one with the decryption key. They open the decrypt page, upload the file, paste the key, and the original file is restored locally in their browser.

Only for the moment it takes to send the delivery emails. The encrypted file is deleted from the server immediately after sending — see our Privacy Policy for details.
