I have only just started using PDFiller.com and I am very happy with the product. My only compliant is that I was forced to subscribe to it without the option of a free trail etc When I did a search on the web for a free PDF Editor, PDFiller.com was one of the websites that popped up, I edited my document (which was a theory paper that I had already spent hours on !!) and when it went to saving it I could not without paying for service... so not a free PDF editor!!! And you can not subscribe month to month, you had to pay for a full year. I know that is business but very deceiving!
