pdfFiller scores top ratings on review platforms
I needed a form and you were able to supply it. The problem is that I only needed that one form and would be unlikely to use this service frequently enough for the fees to be worth it for me. I think this could be a very valuable service for those who would be in a place to make use of it.
Getting acquainted with it. Pretty good. Would be a big help to be able to copy and paste whole cell entry(e.g., multiple-line entry within a cell) into another cell. Also, clumsy toggling between a p.1 and p.2 of a device - several interruptions to tell me the document was being edited.
This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.
I wish there were more typfaces I could use. Also, I couldn't figure out how to italicize titles within the document without it italicizing all around it. I gave up after several attempts. Wish that part were more user friendly.
