Resize pdf dimensions
First of all, not too sure if this is a right place to post this question. If not, mods are free to move to the right section.
Now the question,
In the past, I have scanned loads of books at 600dpi, used ScanTailor and finally made pdfs out of it. I do not have original scan anymore. The size of these pdf is pretty huge and no matter what I do in Acrobat using Resize option, the size isn't getting any smaller. When I look at page dimensions, they are pretty large and practically I do not need such large dimensions of the pdfs.
I wonder if there is any tweak in Acrobat itself that will allow me to resize pdf dimensions or is there any other program that will let me do it on the fly?
Thanks in advance.
