Adobe Reader, software used to view and fill PDF forms, is installed on most every computer. With Adobe Reader, you can sometimes enter data into a PDF form and print it, but you are unable to save the completed form to your computer. Also, some PDF forms do not allow you to fill in any fields. Up until now, the only solution to these problems was to purchase the Adobe Acrobat software package at a cost of around $500. With PDFill Editor you can do the above tasks for a fraction of that cost. You can also add comments, annotations, text, or shapes to the PDF and resave it.
