I am very happy with this software..The Only problem I had was editing text that I had already entered. I read instructions and it seems that the only way to edit text is with the eraser, which is conveniently not included in the standard version. Correct me if I'm wrong.. Thank You

Experience was OK. Site is not clear on how to change type size and document size when filling in form. Also don't appreciate having to use PDFfiler and pay for a subscription just to save my document and print a copy. It contradicts your advertising for a Free service.

I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars.

It was straight to the point. Thank you ****** for being quick and professional.

Very good service Very good service. I used it once to fix my resume and forgot to cancel. Accidentally subscribed for an annual subscription so was shocked to see $321 come out of my account. That was all the money I had. I got in touch with the customer support team and they refunded the money and cancelled my subscription immediately. 10* customer service - love you PDFFiller!
