What our customers say about pdfFiller

I'm going with the default you had.
"Works exactly as expected. Smooth, responsive, and intuitive interface."
That about sums it up. It was so obvious on how to edit text, increase it's size, move it around (great feature!), add checkmarks and Xs.
All around just very good.

On first blush,this is a fine tool. I have a limited number of documents. So this works great. Simple. Easy to follow. Support answered some not so obvious questions quickly and easily. Well done. I have one question or suggestion..I would like to merge a couple of my documents...but don't want to pay for a full upgrade for just two or three uses. Can you offer a "yeah we'll let you do this" one off pricing for someone like me? Would be very helpful. (I will also say I tried several of the competing products...and this was far easier to use)
