What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
After a slow start and feeling misled by the "fill in your form for free" and then having to pay, I did get a full refund. The tech support was excellent - they were the only ones, that I could find, that could get me the rather complex fill in form from NY State Tax authorities (RP-5217). I still feel I should not have to pay a third party to file a required tax form - but that is an issue I'll have to take up with NYS, wish me good luck with that one.

It worked very well to get the 1099's printed for our wards. I am testing it with other things. Anxious to learn how to edit forms I had created when I had access to Adobe photo shop.

What do you like best? Editing, merging and marking-up PDF documents and particularly drawings (I am an architect) is easy to do on the program. Editing, deleting selected pages and merging are the most common features that I use, and this is easily done on pdfFiller. It would be helpful if the program has better ways to draw lines and circles, etc., as these are basic needs when marking-up drawings. These features need to be improved. What do you dislike? Drawing features are not user friendly and need to be improved. Highlighting, which is available on pdfFiller, can only be done in straight lines and not at an angle or in curved shapes. This needs to be improved. What problems is the product solving and how is that benefiting you? Editing and merging PDF documents, marking-up PDF drawings. These are my most critical needs for document review and pdfFiller allows me to do all of this easily.

What do you like best? The ability to change/save PDF files, the online signatures, the ability to delete unwanted pages in a PDF. What do you dislike? The auto "next" field selector thing...I figure out a way around it, it's just annoying. What problems are you solving with the product? What benefits have you realized? I'm a CPA and I can easily type important forms for federal and state governments to keep them professional and easy to read.
