I never thought about it, but I do use it a lot, some of the things in there I didn't even realise were difficult.

I use it for resizing images all the time for sure, it's quick and easy The markup tools are nice as well to quickly annotate things for sharing in the team, although for some reason it always takes me a little bit figure out how to unlock the toolbar.

I had no idea simple edits to PDF were such a pain for other people
