Very helpful.I use I-Pads most of the time with PDF Expert to fill in. However, when I am in need of using a PC or non-touch screen, this has been by far the best and easiest fill-able software I have used!

Fácil de trabalhar no computador, no celular não gostei muito, as ferramentas não tem a mesma funcionalidade para editação e não tem opção de deixar em português.

I love this app just wish when using the Text Feature, when filling in a form with white space, that you could move the text box if it is not aligned .

I wanted to create 2 additional 1099s but was unable to find that option so closed and requested it be sent to IRS. Now I know I should have selected "template" but have not been able to get that to work. Made another, and no option to send to IRS

Very simple and incredibly useful. This is my secret weapon as I can change, modify or update any PDF document and have it ready to go within minutes. Probably my most useful app.

This program is the best viewer and editor of PDF files that I found online and free. It is a utility or extension that we can add to our chrome browser to open directly from our inbox, those files with PDF format, without the need to invest great efforts in downloading and installing heavy programs that deal with that work. I mean, it's so light that its discharge is super fast. Once the extension is installed I must refresh myself mail, I believe that this work should do directly the inclusion process of the extension in chrome. It is hardly a detail if we compare it with the great advantages that this product offers us.
