    • ? Frequently Asked Questions

    Q What's the difference between user password and owner password?

    User password is required to open the PDF. Owner password allows changing security settings and permissions. You can set the same password for both, or use different passwords for extra security.

    Q Can I remove the password later?

    Yes! Use our PDF Unlock tool if you have the password.

    Q How strong is the encryption?

    We use AES-256 encryption, which is industry-standard and highly secure.

    Q What if I forget the password?

    If you forget the password, the PDF cannot be opened. Make sure to store your password securely!

    Q Can protected PDFs be opened on any device?

    Yes! Password-protected PDFs can be opened on any PDF reader that supports encryption, including Adobe Reader, browser PDF viewers, and mobile apps.
