What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It does have a few glitches, but overall, it's a nice product with plenty of good features. The original annual price of $72 was too much for the few times I would use it in the course of a year, but the special rate of $18 was reasonable. If I would use it more, it would be worth it, although I hate subscriptions. We'll see if I use it enough to justify renewing next year.

This program was easy to work with; however, I misunderstood that the forms I was trying to use were copyrighted and had to be completed in another manner. Customer service was very prompt in responding to questions; and, for the right forms, this would be an awesome service.

Helpful Tool
I had been trying to send off some release forms and was crunched for time so I signed up for PDFFiller's free trial. In the end, I wasn't able to use their software without a purchase, but it made me almost wish I had paid the money.
I like that I can sign any document electronically. It definitely saves time and printing costs. It cuts out about 2 extra steps: printing and scanning. This is helpful for documents that need signatures such as release forms, etc.
I didn't like how much I had to pay in order to use my e-signed pdf. I don't use the software often enough to make it worth the price.
However, if I worked regularly with documents that needed to be signed this software would be the very best solution.

PDFFILLER
PDFFILLER, I have tried many and many have failed, typically to overstate and underdeliver, however. PDFFILLER, is the nerd in the room understated but delivers at every turn. There have been times though that I was sure they misssed something, that is untill I call support and talk about delivery. A product is only as good as the support team behind it. Hours spent trying to figure out this glitch, testing this and testing that, and the support agent just as friendly and helpful at hour three as at hour one, come to find out, it was my network, my VPN and firewall wasn't letting me upload documents, others were good and worked fine. except from my phone. Even then the agent was doing even more testing and providing his findings via screen recordings over email. I was amazed and it wasn't the first time. incredibly knowledgeable and professional. I am not an easy person to please as most software isn't completly vetted before release but PDFFILLER has done their work and worth every penny.
