What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I use PDFfiller on an iMac which does not have Flash installed. The main problem I have is that some of the text I deleted in a PDF file using PDFfiller appears to remain in the file. After I save the file, exit PDFfiller, and reopen the file with PDFFiller, the text I deleted was actually deleted and no longer in the file. So these steps serve as my workaround to this bug in PDFFiller on computers without Flash.
I greatly appreciate the PDFfiller Help Team explains the reasons why the bug remains in the current version of PDFfiller, transitting from requiring Flash to not requiring it.
Furthermore, as a software engineer myself, I fully accept the reasons for this bug to remain in the current, transitional version of PDFFiller.
Thank you very much, the PDFfiller team.

Pdffiller, great if you fall into the niche
I love being able to merge several photos into one pdf without having to worry about awful formatting. It's pleasant to use and it gives good results.
This product is not actually free (in my experience) I would appreciate free trials without the need for credit card info.
