What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It has allowed me to "type" forms that I would have otherwise needed to hand write or type on an old fashioned typewriter (which I still have). I didn't like the way the numeric columns lined up. I didn't see a way to insure that they were all right aligned.

The billing is bogus and felt dishonest, but customer service fixed my problems after an email. These save well as pdfs but not as docs. I think the service should be less expensive, given apps with similar functionality.

I used the *** filler and editing program for about a year. It was great and easy to use on a daily basis! Unfortunately, I no longer need to use this program since I have changed jobs. I was not able to access my account in order to cancel my subscription. But, the customer support team was very responsive and helpful. They helped me cancel my subscription on the same day that I submitted the request. Excellent service! Thank you!
