PDFfiller works well and is intuitively easy to follow. I used it for my company's W-2 and 1099's. The forms could be easily found, filled and printed without any problems.

I wish it would edit pictures so I can erase and/or add text; it is not very accurate in determining the the input areas on forms; it changes the font on some .pdfs that are uploaded.

easy to use...but...make so forms can be shrunk so they aren't huge all the time when open, when they are huge and cannot be shrunk it can give you a headache...templates for forms ( or any often-used form) should stay at the top, to find them easy, instead of sinking down the list...you have to hit at least 5 buttons to print, and that is horrible...

This service is a lifesaver. If, like me you don't have original adobe software and only occasionally have to fill in PDf's, PDFfiller has made life easier. So simple to use - brilliant!

So Far, so good! I have only used it a few times, but I LOVE the fact that I can fax items. I would like to learn more as I am sure that there are a ton of things that I can do that I dont even know about!
