PDF files by Adobe cannot be modified by using the ordinary Adobe Acrobat Reader. You have to have some sort of software that can do updates on the said files. Perhaps a software like pro version will do. However, you are only limited to them being PDF files.
A better way is to convert such PDF files to Microsoft Word format. After all, many of us use Microsoft Office so a pdf to word converter is a more viable solution than purchasing a software that is limited to PDF files still.
Quick-PDF is a PDF to Word Converter that is pretty much easy to use. Its main features include high quality conversion, command line mode, all pdf formats support, batch conversion and built-in ocr module for scanned pdf’s to name a few.
The most important feature is its ease of use. Nobody likes using something that is complex to use. Even I would get discouraged right away if something I want to do takes so many steps to accomplish.
Simply drag a desired PDF file to program’s window, then click the Start button and let the application do the rest. Easy, right? And so far, I have noticed that the accuracy of conversion is perfect. They look exactly as it did before that.
