What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
PDF filler has been a life saver! So many times I have been required to fill out documents that most would typically print out, fill by hand, scan, and email back. PDF filler has allowed me to save time by being able to fill out the forms digitally, tremendously increasing my productivity and turn around time. All documents are neat and professional-looking, including my digital signature! Initially I was unsure about whether or not it was worth spending the money on PDF filler b/c I wasn't sure how often I would be using it, but now I would definitely say it's worth it! An absolute necessity for any business to have to get things filled out quickly and neatly!

The only reason my rating isn't a perfect 5 Stars is regarding getting an a document notarized online. Your website says it will be at no cost. But when linked to the vendor notary person, she said the cost is $25. When I contacted your company a couple of times, it was indicated someone would get back to me w/ answer. But that never happened.

What do you like best?
I love that this is a user friendly and cost efficient alternative to PDF editing. I have found that it can do everything (and more) than other services can. It is easy to use and excellent solution for our company
What do you dislike?
The SINGLE thing that I am not a fan of is the fact that encrypted pdfs can be sent but NOT returned encrypted. Sometimes I will send a form to an employee and need the PDF to be encrypted returned back to me and there is no option for that.
What problems are you solving with the product? What benefits have you realized?
The encrypted services have been a burden but the benefits are abundant. It is a great tool and I love that I can send our employees forms to fill out and they can receive/return them from their phones.
