I love PDFFiller, but I know I won't be using it often. I wish you guys have pay-per-use option instead of paying for a whole year. If not for this very important court doc I'm filling out, I won't even consider paying for a whole year.
Michelle J
If the pop ups on the forms would stop that would be terrific. It would also be nice before I go putting all my personal info in the form that you put the price up front.
Douglas C
I was pleased to find the AIR realty forms on your site. We're trying to sublet our space in a commercial building and our landlord insisted on using the AIR forms
Richard F
It does make my life quite a bit easier to edit PDF's. However, if there was an actual way of actually being able to edit the words already typed previous (rather than erasing lots and retyping and aligning) that would save me a lot more time! Am I missing it some where on here? Is there a way to just edit previously typed PDF's?
Jonathan C
What do you like best?
Allows unlimited potential to edit virtually any document and send it electronically or conventionally. This software is a time saver/life saver.
What do you dislike?
The drawback. The Eraser tool. This tool could use some work as far as the shape of the tool. The option to be circular as well as the normal shape would be of great assistance when editing. A competitor of yours, sorry to mention uses an eraser too that is amazing and I have thought of switching simply for access to the editing qualities of that software. It allows for the one time purchase of their software and I would not pay monthly fees to maintain it either.
Recommendations to others considering the product:
Try out the product and use it!! See what you are missing!!
What problems are you solving with the product? What benefits have you realized?
The editor allows our office to clean up and mark up documents received in our office such as lease agreements or forms attached to a policy which either enhance or negatively impact the clients coverage from year to year. We directly not on those forms in our proposals during renewal negotiations so the client has specifically seen and reviewed how the coverage impacts their insurance needs.

I like the concept, but slow I like the concept. But the processing is awfully slow. I'm going to buy a membership for my team, but I just wish everything processed more quickly.
Jonathan Tate
Great app Great app - really easy to use. Doesn't change the quality of the document. Probably won't pay for it long term - I would pay £1 or something everytime i wanted to use it though...
