Adobe products come with a tool that allows users to lock the content of a PDF so that it can't be altered. To unlock the content, you will need the password that was used to lock the PDF. Although the PDF is locked, you can still copy and paste it to a word-processor created document, Web page or other document that accepts PDF files, by using a tool in Adobe Reader. This article includes instruction for how to copy, and paste, files using Adobe Reader 8, 9 or X throughout.
Open the locked PDF document in Adobe Reader.
