What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
PDF filler seems to be very useful. Is/was slightly difficult to figure out but once understood is fairly easy to use. Unfortunately the price is too high for those of us on fixed income. Is there anything lower cost for disabled seniors? Please?

I write reports for evaluations. Litigation has mandated that these reports be quite extensive. Handwriting them took hours. Scanning the forms into a pdf and allowing me to edit them is immeasurably helpful to maintaining my sanity.

What do you like best?
I love that this is a user friendly and cost efficient alternative to PDF editing. I have found that it can do everything (and more) than other services can. It is easy to use and excellent solution for our company
What do you dislike?
The SINGLE thing that I am not a fan of is the fact that encrypted pdfs can be sent but NOT returned encrypted. Sometimes I will send a form to an employee and need the PDF to be encrypted returned back to me and there is no option for that.
What problems are you solving with the product? What benefits have you realized?
The encrypted services have been a burden but the benefits are abundant. It is a great tool and I love that I can send our employees forms to fill out and they can receive/return them from their phones.

Filling in the pdf was great, however when I saved the file using "Save As" the text was not spaced out in the boxes but overwritten making it difficult to read.

My experience was good with pdfFiller. I just don't feel that I would use it enough to keep the extra expense! This was my response and I truly liked it a lot but I don't think that I would be using it enough to warrant the extra expense.
