Suppose I have a PDF and I want to obtain whatever metadata is available for that PDF. What utility should I use?
I find the piece of information I am usually most interested in knowing is the paper size, something that PDF viewers usually don't report. E.g. is the PDF size letter, legal, A4 or something else? But the other information available may be of interest too.
EDIT: Here is a handy guide to paper sizes, thanks to @terdon.
