Once I became familiar with the input it was pretty easy to use. However trying to Print was difficult. The on-line help didn't suggest using the DONE button!

An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC

This product worked beautifully! I would continue an ongoing subscription but only needed for some back tax forms. Very nice product. I especially liked that I could save it in Word to continue working on it after the subscription ended. Thank you.

There are things I still can't figure but overall, I am getting the hang of it and it seems fine. It takes a while to go between pages but that could be on my end.

It was easy to sign and save my document with no interruptions or gemecs in between. I thought it would of been hard to get it sent via email but that was even more of a breeze.

PDFfiller is a great resource for business needs and ordinary forms we use every day. I'm finding as I use PDF filler more, the more I see the value for business and tax time. I'm still exploring PDFfiller. I've not had a problem using the program and instructions are available. I have not had to call for help yet, but I know if I do I will be greeted and questions answered, very professional platform.

Why can't I edit a PDF in Word?
Word does not actually allow you to “edit” PDF files. To do that you need a program that does “OCR” to extract the text from the static PDF images. What Word does is very limited, IF the PDF has been saved in the right PDF format, the text is stored separately from the images. That text is all that Word can access.
