PDF Password allows to password-protect PDF documents.
Drag and drop a PDF file unto the PDF Password window. In case the PDF is already password protected, you can unlock it by providing the correct password.
You can then specify a password and save a password-protected, encrypted copy of the PDF. Leaving the password field empty will save a copy without password protection and without encryption.
