I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

When I do the online fill out the form for application for a China Visa could not print out the form until I installed PDFfiller. Anyway, Thank you for your help.

It was quick and convenient. The only problem I had is that the updated form was not the correct one sent to the email. It continued to send and older version.

Makes pdf edition easier
In our office we need to fill a lot of IRS, FDOR and Court forms. This software allows us to fill them and save them a feature most of the governmental entities don't allow us. It also allows us to erase and edit all pdfs which makes our lives easier. It also allows you to load a document from every possible location, even has its own data of forms.
What I don't like about this software is that in order to go to the next page you can't roll down you have to switch pages and sometimes I end up missing a page of the document.

This is the best tool I have found thus far. I create digital workbooks for virtual training sessions and this PDF filler makes using the workbook by participants a breeze.
