See for yourself by reading reviews on the most popular resources:
I love the site, I don't like all of the pop ups though! I constantly have to click out of the pop ups when opening a new form. That is my only complaint! But, all in all, I love this site and it helps me be more efficient.

Great Tool! My experience has been great thus far. The use is seamless whether on my tablet, laptop, or phone, however, it's much easier to use on a laptop due to screen size. I am able to conduct business, receive faxes, scan items, edit forms, and more while on the go. This makes life a BREEZE! I am never really disconnected from work unless I choose to be. I would say the monthly payments are ongoing and never end. In real life, things like software have a finite value, however, I haven't seen an all-inclusive tool for less.

Great for easy form creation for end users I love that you can make not only nice, user-friendly forms, but they become user-intuitive with this product. This takes the process ahead of just creating a Microsoft Office form, but allows you to create sophisticated forms that can be filled and even electronically delivered. Often the layout gives me trouble or won't let me create form boxes in the appropriate area because it keeps snapping them to the grid, which might not automatically line up to my form fields as well.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL

I somehow allowed my subscription to renew, when I actually do not need this service. A quick contact with customer service handled the problem for me and I got a full refund. I was aided by a representative named ***. No hassle!
