Confusing.. Registration gets you nothing.. then you end up paying then you can do something. Why Register if you cannot do anything with the form... does not make sense.

This is a great program if you need this service. We needed it at one time, but did not realize we could do this on line. I would recommend it to anyone who is in the business of needing documents filled out, signed and delivered.

Great PDF Filler! We needed and easy way to for patients to sign there name for Covid testing. Before we came across this they were signing with pen and paper and now they sign digitally on and case protected iPad that can be wiped down and sterilized. The iOS pdffiller app then digitally sends the completed PDF to a nurse. The whole process is seamless. PDFfiller is very easy to use. Some features that we love are: -Being able to convert a file into a PDF -Converting a PDF into a Fillable PDF -Creating PDF online. There is also a mobile application for Android and iOS that works great. Initially it was tough finding out where things were and where the files ended up when saved or converted over to be fillable. I think the menu could be simplified and reorganized.
