What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It's a good and intuitive product. the only technical glitch is that some of the larger text boxes are shifted over to the right by a fraction of an inch and outside the printable area of most printers.

At first was a bit different in look and function but after a short time became very easy and logical to use. Still wish you could print directly from editing screen.

One big feature that is missing, as is from many of these types of editing / fill in forms, is the basic "Cut","Copy", "Paste" functions. However once I got use to the program's idiosyncrasies, It has been quite helpful. Oh, one more thing, I think more detailed instruction by some useful examples of how the features can benefit in everyday design of a fill-able forms would make it that much more useful.

I like everything I have tried with the exception of the fact that I cannot download a fillable form to my desktop. I wanted to make a form that I could pull up quickly on my computer when I have a new patient intake. It only allows a link and too many steps to make this a good alternative to the paper and pen format I am currently using.

The only thing that I was unsure of was… The only thing that I was unsure of was how to request a signature, and if the recipient would be able to sign it in pdfFiller.
