I have only been using this pdf filler for 2 days and it is by far the easiet PDF program I have used love the feature of being able to edit a document saves a ton of time.
Joan
I completed the first PDF form and it was a little tough maneuvering through the documents, savings. It was a little disingenuous to wait until I was finished to document to find out that I would be billed annually as apposed to monthly, when the advertising gave the amount payable monthly.
Nannie H
I found PDFfiller through Goggle search after trying numerous other sites. I was pleased at how easy your site was to use, in addition to all the options and of course, the price.

Great and simple pdf editor Easily edit, share and secure pdf documents. This is a basic pdf editor that does everything I need. You can edit by adding text, making notes, make tables, add a signature area, etc. It is also very secure and easy to share and collaborate. Even the free version is awesome. It's not the fanciest, smoothest software but it gets the job done. I would like to see the interface beautified a bit.
Jaq L.
My first time with this App and it seems to be a lot different to Adobe, but easier to operate. I have modified 2 pdf file successfully, and so far (as a new user), not too many 'dropped balls'.

YOU MAY DO A FINE SERVICE BUT WHEN FILING A GOVERNMENT FORM A CITIZEN SHOULD NOT BE SUBJECTED TO HAVING TO GIVE YOU A CREDIT CARD. WHAT IS THE DIFFERENCE BETWEEN THIS AND RANSOMWARE?
Anonymous Customer
What do you like best? It is very helpful to be able to fill pdf's in. It also saves paper and time. I hate having to print a form out, fill it in by hand and then scan it into the computer just to turn around and email it. With pdfFiller I can do the work on my computer, it looks professional and then I simply save it and email it. I also like the fax option. What do you dislike? Sometimes I have a little trouble getting everything just where I want it. But the more I use it the easier it becomes. I feel that I will like it even more the more I use it. What problems are you solving with the product? What benefits have you realized? I am solving the wasted paper and time. I am able to keep everything electronically. Forms look more professional. I do not have to pay a separate service for a fax line which I only use a few times a year, I fax straight from pdfFiller.
