Frequently asked questions
How strong is the encryption?
AES-256 — the strongest encryption the PDF standard supports, the same level banks use. Opening the file requires the password.
Can you recover the password if I forget it?
No. We don't keep your password or your file — if the password is lost, the document cannot be opened.
Is it free and private?
Yes — free with no sign-up or watermark. Files are encrypted in transit and deleted automatically after 24 hours.
