What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I found it relatively easy to use, it would be nice if it had an undo selection. And getting the right size font was not easy. Had to wait for print out to see.

I've had a great experience using PDFfiller. Sometimes, I have single forms to complete, and I forget that I have the service. It's user-friendly. I need to make time to do a tutorial to learn more uses. Also, once I become better familiar, I'll be able to make referrals to sign-up for PDFfiller!

I love to be able to use the pdf filler app much easier and it has become very important for us in documents we need to fill out and sign and send. I would like to see some ease in the selecting the editing of a document, can the display of boxes for each section be less overlapping each other, this may be difficult to do. Sometimes when you have a saved pdf document you do updates rather than create a whole new document, we use them as templates. Right now the easiest way is to create a document in Word, save it as a Word doc and as a PDF doc. Which is okay, often, time is a factor and to quickly update a pdf file would be faster. Thanks for listening.

I wish there were more typfaces I could use. Also, I couldn't figure out how to italicize titles within the document without it italicizing all around it. I gave up after several attempts. Wish that part were more user friendly.

I was able to edit the pdf… I was able to edit the pdf appropriately. When I converted to a word document, the places I had checkmarks in the pdf did not align properly in the word document, but that's really the only issue I had.

I enjoy the accessibility to a large variety of legal forms without preparing them, but the process is not that easy. For a novice user, it is cumbersome and complicated. There should be a tutorial on how to maneuver the program and all of its features seamlessly.
