I can do everything I need to with this program........I like forms that I have been asked to fill out I can scan in my printer and then fill out on here and print out when finished and then send them or take them where they need to go.... Thanks so much...

I AM NEW AND LEARNING BUT SO FAR IT IS GREAT. EVEN IF I ONLY PRINT A FEW FORMS A MONTH THE SMALL PRICE IS WORTH THE CLEANESS OF THE FORM. I HAVE BEEN HAND WRITING THEM AND USING WHITE OUT.. I AM GLAD FOR THE SHARPNESS OF THIS AND EASY TO FIND FORMS ..

I found that PDFfiller allowed me to fill out & print tax forms that were not supported by my tax software.I do wish that your service was bit more straight forward in the pricing. I almost didn't sign up because I felt tricked into using the form thinking it was free. A free form or 2 and I would have signed up 100% no questions. Allowing me to fill it out first then charging me was more like a 50% chance I was going to sign up & pay.

This is the first time I've needed this type of aid, and I've found it to be very useful and relatively easy to use. Sorry, I'm really too swamped with work to do another survey

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.

It's pretty good, but I feel like it could be made better. I have to constantly click instead of just being able to tab to next area. Maybe I am overestimating coders and their abilities =P but thats my only issue.

it has been hard getting back to my document, probably because an icon has not popped up on my screen and the form is not in my laptop document file. it's not letting me add lines to the lists though that might be a hard lock in the form. However the section instruction's say that you can add. Mostly I have only used PDF filler on this complicated form and am learning by trial and error.

Great tool Easy to use and has functionality I need. Think there is some maximum number of pages you can convert at one time so have to break it up.

An Efficient Time Saver It is easy to update the documents with some features of a Word Document. However, there should be more variety in the fonts and I wish it didn't change the original/all font when I edit part of it.
