In grad school, much of my reading comes from pdf files my professors post. Prior to PDFfiller, I would print out hundreds of papers in order to annotate. Now, I can annotate while conserving resources and I have access to the files no matter where or what device I use.

I first tried PDFfiller with a trial subscription and to be honest, I really just wanted it so I could add text to a document and I didn't plan to extend my subscription. But after trying it, I liked it so much, I continued the subscription after the trial and my subscription expires in 2 days and I plan to renew for another year. I'm a freelance paralegal and often need to add text (and complete forms) in .pdf format. The program is also very easy to use and has many great features (like "erase" and different font styles and sizes). My subscription has more than paid for itself and I would - and do - highly recommend PDFfiller to anyone looking for this type of program.
