On downloading PDF files from Internet in the form of e-books, documents, white papers, manuals, etc, it is commonly found that the contents cannot be copied or edited. This is because most PDF files are secured either with encryption passwords or with local restrictions. Usually authors of PDF documents impose local restrictions on the files after creating them so that users cannot modify the data. This helps especially while transferring the PDF files over the Internet against tampering or unauthorized access. Such restrictions make it impossible to edit or copy data from PDF files, extract pages, fill forms, modify images or tables, assemble the documents, create template pages or even sign the documents. However, sometimes it becomes necessary to unprotect PDF files for accessing data in all ways mentioned before.
