Password Protect a PDF File

You need to share a sensitive PDF - a contract, an invoice, or personal documents - and want to ensure only the intended recipient can open it.

Set a password and the PDF is encrypted with AES-256 - the same standard used by banks. Without the password, the file cannot be opened.

Frequently asked questions

Can anyone open the PDF without the password?

No. AES-256 encryption makes the document completely inaccessible without the correct password - it cannot be opened by any viewer, browser, or reader.

Is my password stored on your servers?

No. The password is used only during encryption and is immediately discarded. It is never logged, stored, or transmitted beyond the encryption step.
