Worked well. Looks like a good program. I was only using it for one foerm, and do not feel I need the program. You charged me for a full year $72.00, when I felt I WASA SUBSCRIBING FOR ONE MONEH. PLEASE REFUND TTHE DIFFERENCE.

Just started using the program but have search many times before to find an easy way to access documents occasionally needed by our business. This format fits very well and will certainly increase the productivity of office hours. much thanks, Steve Rowell ( Brooks Carpet Inc. )

This is a tool which I never thought I would use so much! I love it! I think the dashboard is cluttered and not the easiest to navigate, and a "strike through" option for documents would be nice to have.

As an online PDF editor, this service is perfect for me!
Most of my PDF work is minor editing and signing PDF forms and documents. PDFfiller does everything I need and the fact that I can upload documents directly to the site is fantastic!
The form creator isn't free, and you don't find this out until after you spend time creating your form. You have to subscribe in order to be able to download it. If you find it valuable, it's worth the price.
