What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
it does important essential legal functions in ways that work but are somewhat visually disorienting and that are provided through a user-insensitive, extortive pricing model. The fact that PayPal has removed you from their approved subscription list may be entirely technical but it does not inspire confidence.

I find that using your program is easy to navigate and looks professional when completed. I find that using your program is rather easy to navigate. The only issue that I have had is when I try to print a document, there have been quite a few times that it will download to 63% and then gets stuck there. I have to close the document and try again....sometimes several times until I can print it. Besides that, it has been great!

Glad to have it Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.

There are some minor things I have not figured out how to do. Not sure yet if they are just missing features, or just not readily available in a way that I was expecting.
