pdfFiller scores top ratings on review platforms
My only two complaints are the price and the fact that if you only want one page out of a file with a lot of pages... it seems the only way to "quickly" do it is to go in and individually delete each unwanted page. Otherwise, it does most of what I want.
Honestly- it is not straigth forward tool- you need to spend time and learn how to use it so it is not exceptionally user friendly.
I found SignNow very complex!

I know there is more to learn and if I had the time to learn it, I would, but I just don't have the time, am in the middle of moving, so I can't do it.
