How to Protect a PDF

To protect a PDF file with password you can either opt for Adobe Acrobat or any other third party PDF encryption tool available in the market. As far as Acrobat is concerned it is an expensive tool that would not fit in everyone?s budget. And if you?re willing to use any other third party tool we would recommend you to try Estelar Protect a PDF to protect all your sensitive and confidential information in PDF documents.
