PDF creator from PrimoPDF (appears to be related to Nitro). The last time I tried it, it allowed one to enable security on their PDF documents. This does not (or at least it didn’t at the time I tried it) alter those of an existing PDF file, but you should be able to print from your PDF reader to this PDF printer to create a new document with security options enabled.

Well you can password protect it but are you sure the result is what you want? If someone wants the content in a different format they can print and scan (with OCR if they want editable text) or use a screen grab.

Those tasks become a lot harder if you add a whole page watermark or if the document is large – dozens of pages become a hassle to scan/grab.

The best software in the market is Nitropdf which fulfills your requirement, well its cost much as $119.99 for single users.

Nitropdf has been used by many companies and organizations.

There are two types of password option in pdf the first one is to protect files from opening it by UN-authorized users and the second one is to protect your pdf from being edited but using this option any one can read its content of the file but does not edit it using any pdf editor.(use strong password for second option as many softwares are knocks the market which allows to edit pdf files even pass pretected pdf, use latest 15 characters long password with combination of upper and lower case, special symbols and numbers to add more security to your file)

Nitropdf also allows you to edit pdf files and convert pdf to word, excel too.
