What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Overall easy to use, however, there are instances where the edits on the pdf become warped, other times its difficult to remove words or characters. There should be a save option versus a Save As, as that navigates you to another screen. Or have an auto save option. Overall good program but still has small defects.

So far, I am impressed with the PDFfiller. I can do all the things I want to do in a rather straightforward manner. We will see what the future brings in terms of the capabilities I have not used yest.

I wish it would edit pictures so I can erase and/or add text; it is not very accurate in determining the the input areas on forms; it changes the font on some .pdfs that are uploaded.

Impressive features and easy to use. My only gripe is that there appears to be no way of changing the date function to day/month/year, but it's just as easy to enter the date manually
