Frequently Asked Questions
Do I need to know the password to unlock the PDF?
Yes. You must enter the correct password to decrypt the file. The tool verifies the password locally and removes the encryption if it matches.
Can I unlock a PDF that I don't have the password for?
No. Without the correct password, the PDF cannot be decrypted. This is by design to protect document owners' privacy.
Will unlocking a PDF change its content?
No. Only the encryption metadata is removed. All content, images, fonts, and formatting remain exactly as they were.
Can I unlock a PDF that has both an open password and permissions password?
Yes. Enter the open password (required to view the document) and the tool will remove all restrictions.
