I LOVE pdffiller, but need to know more about how to use it. For instance, how can I hide the "establishing a secure connection" message when the form loads on my webpage? And how to change the color of the highlighted fields?

The PDFfiller service was very comprehensive and easy to use. I really appreciate the options for document delivery and would recommend this service to colleagues who could benefit from this service.

So far great! Just wish we had more options on auto-page numbering. If your document has a cover or a forward like a book, those are pages you don't want numbers on.

This is a good program, but it could be more user friendly. Copying the edited PDF from the online program to my desktop was more difficult than it should have been.That said, I was able to accomplish what I wanted via this program.

I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars. I reached out to support and ****** returned my email within minutes. I provided my information to customer service specialist ****** and he fixed the problem. There wasn't any back and forth emails. It was straight to the point. Thank you ****** for being quick and professional.
