FAQs
Common questions
What encryption is used to protect my PDF?
Your PDF is encrypted with AES-256, the same strong standard used by banks and governments. Anyone opening the file will be required to enter the password you set.
Is my password stored anywhere?
No. Your password is used only to encrypt the file during processing and is never saved or logged. Once the encrypted PDF is returned, the password exists only in your hands.
What happens if I forget the password?
There is no way to recover a lost password — that is the point of strong encryption. Be sure to store it somewhere safe before sharing the protected file.
Can I protect a PDF that already has a password?
Not directly. If your PDF is already password-protected, you'll need to remove the existing password first before applying a new one.
