So far so good. I don't know why when I add pictures it doesn't come through in the email. Plus, I don't know how to edit a form once I've completed it.

I live in Philadelphia SEPTA is not running because of contract issues but my military ask that I complete a form and send it to them within five days or I would be subject to pay large amount. Since I could use PDF Filler that lets me fax , signed update all at once I made the deadline without leaving my home ... I sent this out to many of my friends we all need a choice to fax and complete forms ASAP

It took a few minutes to learn navigation, but once figured it out all is good. Still many features that i have only scanned thru that really look very helpful.
HAROLD R S
I like that I can create a fillable PDF… I like that I can create a fillable PDF and merge documents together. This program has a lot of good features that other companies don't offer.
Susan M.
A solid editor with a very minor flaw imo Other than a better scroll bar for the area of the documents being edited, the interface is pretty easy to navigate if you have used any similar programs (such as adobe acrobat reader). I wish there was a less feature oriented version that was free to use/download, perhaps with a daily/weekly task limit, similar to things like smallpdf.

My only use is to help my 14 year-old grandson with his Eagle Scout Service Project report. I'm retired and have no further use for the program beyond next year when he has completed his Project.
