Always protect PDFs containing Aadhaar card, PAN card, bank account details, salary information, medical reports, legal contracts, property documents. The rule of thumb: if you would not want a stranger to read it, protect it with a password.

If you know the existing password and want to remove it, use the same Protect PDF tool. Upload the locked PDF, enter the current password to unlock it, then save without adding a new password. This permanently removes the password protection.
Protect PDF from Printing and Copying
Besides a password to open the file, you can restrict what the recipient can do with the PDF — prevent printing, prevent copying text, and prevent editing. This is useful for sharing confidential reports or proprietary documents.
