This is fabulous! I was using Nuance PDF Converter, which has worked fine for many years, but it couldn't handle a couple of the 2013 IRS forms...So I did them here. And it worked!

I'm just beginning and not sure I'm using it correctly. what I'd like to do is to be able to simply use the icon in my internet task bar to open the account rather than have to open up pdffiller.com

I really like the fact rhat PDF filller allows me to work on very important PDF documents that I need to fill out but I still have trouble navigating these documents which is why I only gave 4 stars. Maybe with better instructiins...

What do you like best?
I love that I can make any document filler-friendly. My handwriting is atrocious. I've completed applications, tax forms, and more. I love that I can move my text around. Love that I can easily insert check marks.
What do you dislike?
Sometimes I struggle a bit with saving my documents. I sometimes want to save one as a blank and one as a completely filled form.
Recommendations to others considering the product:
Yes! It will make your life easier!
What problems are you solving with the product? What benefits have you realized?
It's so easy to change a document I might have goofed up! I can make the change and reprint. Done. It's been a huge timesaver for me. I can prefill certain parts of a form I have to use over and over which saves time.
