pdfFiller scores top ratings on review platforms
I enjoy the ability to convert PDF files back into MS Word. Very Often I will start in MS Word and send the document to an employer who then sends me a final version in PDF which is OK until such time as there is a need amend it. As I don't travel with a copier, printer or scanner this creates problems.
I subscribed for one purpose - to be able to print numerous amounts of Genealogy Forms. This is fulfilling my needs with minimum issues. It is a great product.
Easy way to fill out. Don't have to print and scan. Very clean. I liked the signature filler. Just uploaded and place wherever there's a signature and shows up with PDFfiller date stamp
