What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I just started to use PDFfiller and like the ease of completing pdfs, and logical flow of the app! Also love the send fax feature although while it seemed to work well from the desktop app, it seemed to hang when faxing from my galaxy Note 4 (just kept spinning and I had to force stop the app)-- will have to try faxing more to see if it was a device or app issue.

I have had limited use since I became a subscriber. I have difficulty printing the PDF file I was working on and asked your online help desk what I could do to remedy that but without success.
