What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
PDFfiller was intuitively simple to use in creating an important document. I had difficulty erasing some text I accidentally superimposed onto my document and the recipient who ultimately got the PDF I created could not open it. Also disappointing was the fact that I didn't realize I had to pay a tidy subscription price until after I completed my document and tried to send it off (and save it). That all led to an initially horrible review.
But, I have to say that my experience with PDFfiller and Elie, the rep I dealt with, revised my entire experience. Not only did Elie help resolve the problems in a very timely fashion, I received a refund! PDFfiller seems dedicated to provide the user an efficient product and the customer service is the best I've seen with any internet-based business. Elie is a great ambassador for the business and she really follows through with her promises! I never expected that. They are also going to revise some aspects of the user interface to ensure proper notice of expense and conditions of subscription. I will certainly use PDFfiller in the future!

PDF filler is easy to use and let's me change documents as needed.Unfortunately, some of the features available on the computer are not available on the Ipad. Creating fill in lines for example.

Not the easiest to figure out initially, and detailed instructions are a bit hard to come by, but it seems to do what I need it to do to make signable forms and merged PDF's.
