Thought I would share this link with you that I found today, as the title states, it’s a website that allows viewing and editing of PDF files online, the best bit.. it’s free!!
I was looking for some software that would allow me to add notes to my university lectures that are in PDF format (to save me on printing), when I came across it
It’s called PDFescape and it can be found here.
I can’t promise it’s perfect (I’ve barely used it), but from what I’ve seen, it’s good!
