Frequently Asked Questions
How does PDF password protection work?
PDF password protection adds a password requirement to open or modify the document. This tool prepares your PDF for encryption.
Is my password stored anywhere?
No. Your password is only used in your browser to process the PDF. It is never sent to any server.
Can I remove the password later?
Yes. Use our Unlock PDF tool to remove the password from a protected PDF if you know the password.
