What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I LOVE pdffiller, but need to know more about how to use it. For instance, how can I hide the "establishing a secure connection" message when the form loads on my webpage? And how to change the color of the highlighted fields?

This is a good program, but it could be more user friendly. Copying the edited PDF from the online program to my desktop was more difficult than it should have been.That said, I was able to accomplish what I wanted via this program.

Only day 1, but so far so good. Love that all my files are stored in one place to access from any computer! Easy to use and email files. Great investment so far!

I have yet to use the on-line features. Still deciding if I want HIPPA files out there. I don't know where your servers are located, but if they are outside of the US then I'm concerned about where and what the privacy laws of the "domain" country are. I ran into this issue years ago setting up some legal files. All servers were required to be located within the US.

I struggled a bit when the form was completed because I failed to see where the "Print" button was located, but a rep from Customer Care (Paul) helped me and I was all set. Looking forward to exploring and using the PDF filler site frequently.

SIMPLE AND EASY TO UNDERSTAND FOR PEOPLE WHO ARE NOT TECH SAVY ITS GOOD BUT PRICE SHOULD BE MADE RESONABLE SO THAT MORE PEOPLE CAN AFFORD AND USE YOUR TOOLS. FOR PEOPLE IN INDIA IT IS STILL EXPENSIVE. IF YOU REDUCE YOUR PRICE, IT WILL BE AFFORDABLE TO MANY AND YOU WILL HAVE MORE CUSTOMER VOLUME IN INDIA THAN ANY OTHER COUNTRY. THIS WILL HELP YOU GENERATE MORE REVENUE.

I was surprised I still have to hand… I was surprised I still have to hand write a form to send to IRS - I thought this would take care of it for me. Or did I miss something.

So far everything seems to be working effectively. Only had one inconvenience and that was when I tried printing and I kept getting a black block on the signature panel.

Top notch customer service! Accidentally subscribed for an annual subscription so was shocked to see $118 come out of my account. I got in touch with the customer support team and they couldn’t have been more helpful. They refunded the money and cancelled my subscription immediately. 5* customer service - well done PDFFiller!
