Frequently Asked Questions
Can this tool crack or hack a password I don't know?
No. DocuPlier is a professional utility, not a hacking tool. To remove a 'User Password' (open password), you must know the password. Our tool simply automates the process of saving a decrypted version for your convenience.
What is the difference between an Open Password and a Permissions Password?
An 'Open Password' (User) prevents anyone from viewing the file content. A 'Permissions Password' (Owner) allows viewing but restricts actions like printing, copying text, or editing. Our tool can remove both types.
Is it safe to unlock confidential documents?
Yes, because the decryption happens entirely in your browser's local sandbox. Your file and the password you enter are never sent to our servers. This ensures 100% privacy for your most sensitive data.
Will the formatting change after unlocking?
No. The core content (images, text, layout) remains exactly the same. We only modify the encryption dictionary in the PDF metadata to remove the security constraints.
