Frequently asked questions

How do I password-protect a PDF?

Enter a password, upload the PDF and download the encrypted file. Anyone opening it will be asked for the password.

Is encryption strong?

The file is encrypted with standard PDF encryption (AES). Keep in mind that a password protects against opening, but anyone who knows it can read and share the content.

What if I forget the password?

A forgotten password cannot be recovered — the encryption is one-way. Store your password safely.
