Love the program. Its easier than what I am making it out to be .... therefore, it is somewhat hard to learn what to do (because so much is done for you!) :)

I did not like the fact that when you decided to make it a service that charges you money, there was no warning. It forced you to pay if you wanted to keep your documents. I'm past that now and I am really ENJOYING it now that I am a paying customer.

Great PDF program for mac users I absolutely love pdffiller! I just wish it was either cheaper per month or maybe could be bought for only one or two months when needed.

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!
