What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
on the form 710 you cannot remove the zeros on page 2. Please correct ... I use this form a lot and it would be nice to have fillable spots vs lining up the curser.

I needed to fill out a one-off 6 page form and was looking for a free app to do it. When I Googled for this you came up and I did not track it was not free until I completed the form. Then I was "stuck" b/c I needed it asap and the request for payment did not come up until the end. I was not happy and would never have used the program had I tracked what happened. That being said, it was an excellent program and if I had to fill out forms routinely, I would recommend it. But since I don't need this app, please cancel my subscription.

We love the power PDFfiller gives us to export data filled in to be exported to Excel and manipulated. For the most part, it is a very intuitive program. There are some aspects of set up that are confusing, but customer support is GREAT, QUICK, and seemingly PATIENT. We are very happy so far with its performance.

What do you like best?
I enjoy very much that I can scan in documents and then fill in and add things to them easily.
What do you dislike?
Very little. But sometimes I find I accidentally click on the up/down bar instead of the buttons. Also, some of the buttons are not intuitive, but trial and error works well, and mistakes are easily deleted.
What problems are you solving with the product? What benefits have you realized?
I used to need a type writer (or hand write) sometimes still to comply with using the forms given to me by the government. Now, I can upload them and use the computer. Much better.

So far
So far, so excellent. User experience takes a little getting used to, but a quick google shows you how to do it. And I haven't found anything yet that it wont do. Great tool. Used it for about 40 documents so far. Splicing things together, re-wording and cutting and changing dates. Basically editing everything imaginable in pdf.

I use a clunky chromebook and needed to fill in an enormous health history form. This pdf filler was the easiest experience I have had with one of these assists. As I rarely need to do this I did not continue the subscription and the customer service was excellent I do highly recommend pdfFiller.
