When I started searching for a PDF to Word doc. a few days back, I downloaded 4 different trials and hated all of them!! They were not user friendly like this one is!! To anyone reading this, DO NOT waste your time researching other apps, you will not find anything better then this one! I would absolutely recommend PDFfiller to anyone who is reading this!!... and so will you.
Tina S
Exactly the form that I required. Repeated editing was necessary for approval of recipient and permitted by PDF filler. Direct email was most helpful to pre-empt time delays. Anticipate emailing for initials & signature - hope it works out.
