I stumbled onto this software product because I needed to redo a 2012 - 1099 form. Since then, I've used it for other forms and I LOVE THE SOFTWARE!! I can't tell enough other people how great it is.

Its a real good software, I think that people really can used it, maybe there should be a program that pay by used not a regular monthly charges. I am a every six month user.
2016-05-13
I have been able to ask questions by email and by live chat. I needed to be able to sign documents and now i need to be able to convert docs to PDF and am pleased to find a way to do it.

Great Product
This software has helped mainly with electronic signature creation but also with overall PDF edits.
The software offers a number of options for editing PDFs and is fairly user-friendly. It has an easy layout.
I do not like the fact that the software can lag when working with slightly larger documents. It can also be time-consuming to learn more advanced features.
2019-11-09
I love the PDF Filler. The only thing I don't like is the fact that when editing the font changes from the original font on the form that I am trying to edit.
2022-05-30
It is a bit frustrating to learn how to send it to my computer to be accessed and modified as needed. Right now it serves me as a trial, but I wouldn't pay for this.

Pdffiller has by far the best support…
Pdffiller has by far the best support team that I have ever experienced. They can be contacted day or night to help resolve any problem or question I have had. They are fast and provide answers promptly. They even send links or videos to show you how to solve the problem. Pdffiller is great for sending fillable and signable documents used in the medical field because they offer hippa compliance, encryption and secure cloud storage. I highly recommend pdffiller.

Great program
Great program. Let's you edit PDF, sign documents, send documents to clients or other persons to sign electronically. Also gives access (at least my package) to some limited legal forms which is helpful. Would highly recommend.
