How do I add password protection to a PDF online for free?

Upload your PDF, select "Add Password", enter your desired password, optionally set permissions (print, copy, edit), and download the encrypted PDF. Uses AES-256 encryption for maximum security.

How do I remove password from a PDF I own?

Upload the password-protected PDF, select "Remove Password", enter the current password, and download the unlocked PDF. You must know the existing password - we cannot crack or bypass PDF passwords.

What encryption does the PDF password protection use?

We use AES-256 encryption, the same standard used by banks and governments. This is the strongest encryption available for PDF files and is virtually impossible to crack without the password.

Can I set different permissions like preventing printing or copying?

Yes! When adding password protection, you can set granular permissions: allow/prevent printing, allow/prevent copying text, allow/prevent editing, and allow/prevent form filling. Owner password controls these permissions.

What is the difference between user password and owner password?

User password is required to open/view the PDF. Owner password controls permissions (print, copy, edit) but allows viewing. You can set both for maximum control or just one based on your needs.

Is PDF password protection done locally? Is my file secure?

Yes, 100% secure! All encryption/decryption happens in your browser. Your PDF and passwords never leave your device or get transmitted anywhere. Safe for highly confidential documents.
