A user can get rid of a cumbersome task of paper files or record keeping system by effectively using the computer application.

There are several ways to prepare and edit the PDF files. A person can create the files in an editable format such as Word or Excel file. For instance, if you are preparing a report or project for making a presentation to the clients, you can create the document in a Word file format. If you need to present your financial data, you can prepare the data in an Excel sheet. If a person needs to present an image in a PDF file format, he can use JPEG or any other image file format. Once you have prepared the format or the document, you can use a variety of tools in order to convert word to PDF or Excel sheet. A person can even create a PDF file out of a Postscript document. Some of the latest technology based computer programs encrypt the file with a password as a result of which your files are always in read only mode. There are other authors who disable any of the features of a Portable document with the passwords. For instance, you can disable the reading, copying or printing ability of a document. In order to update these non-editable files, you can use the same computer programs in order to convert them to editable text. During the process of conversion the original formatting is not hampered. After making the necessary changes and customizing the file as per the requirement, you can convert the editable text back to non-editable document.
