Allows me to fill in pdf documents with computer so I don't have to print out and fill out manually. Not sure why text moves to next line below in some cases.

It's early, but I like the versatility, and I found it a useful solution while updating my existing resume. I need to continue to use it, though. Need some experience still.

Great software for the money Great software for the money. Has helped tremendously with our business needs. The only thing I would change is the LinktoFill. This gets confusing due to saving a file when you make updates to it and then you end up with having the two files. there should be an option to update exsiting file. Besides that, great program.

So far so good So far so good, I use Adobe Acrobat Pro DC at home and at work, I am still on my first day of my 30 day trial of PDFFILLER but I'm impressed so far. I particularly like the library and search features. More to come as my experience develops.
