I had a very complicated question pertaining to a credit card charge, (I didn't know which account within our company had incurred the charge, and therefore, couldn't track down a receipt) **** helped me reverse engineer the charge to find out where it came from. My company provides Customer Support for the Video Gaming industry, so I know the value of a positive CS experience. Way to Go, ****!

Auto Renewal Charge
I was auto charged for a 2nd year for this service via PayPal. I do not need it and was surprised to see the charge. I contacted customer service via chat and they immediately issued a refund with no questions asked. I received an immediate email confirmation. That is customer service. Thank you pdfFiller.

Easy to navigate and use. Super quick and convenient when having to send completed forms for work or doctors appointments, especially if you do not have a printer/scanner.

I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.

Its been extremely user friendly and I really like the verified signature feature. Its has simplified my document process so much.
