What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
No issues once I contacted the support department who answered my questions. I understand that you are in business to make money on a service. I just felt it was costly for a piece of paper or two that would cost me 10. Cents at a FedEx or Office Max type business.

So far pleased; however actually thought there would be a charge every month as opposed to one lump charge; my fault should have looked into it furthe

This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.

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!

This software seems to be nice and easy to use, im still working my way round it. I was looking to send a form to be returned filled in. Looks like this should be easy enough. I will keep my fingers crossed.

Some of the text sizes seemed to change when editing, and the positioning of the text didn't always seem to be consistent with existing and added text

What do you like best?
I have been using PDFfiler for more than 4 years. It makes my pdf documents look professional. There is no longer a need to print a doc, fill it in with pen, scan, and send. PDFfiler reduces the amount of steps I have to take to get the job done. It helps to also have everything saved on the My Docs page. I can find the same tax documents I need month after month. PDFfiler also reduces the amount of paper needed to generate a document. I probably use PDFfiler every day.
What do you dislike?
I would like to be able to turn off the assisted pop-ups. They can obstruct the box I want to enter text.
Recommendations to others considering the product:
Simple to use. Makes your docs look professional and neat. Easy to manipulate a doc that is incorrect.
What problems are you solving with the product? What benefits have you realized?
I fill out every form on PDFfiler. It's automatic to me. In addition, when I am unable to edit a Word doc or other pdf, I know I can upload it to PDFfiler and get the job done right away.
