I want to copy a pdf file to email, facebook, etc., using windows 8

use cutepdf writer and install it in your system then you can copy all you want in your browser using this software in pdf format.just download the software in google for free.

How? ex:you want to copy all the articles in yahoo,the images and etc.then just
tab File- Print- the small window will appear and let you choose your printer then choose cutepdf writer the wait until another small window appear then assign destination folder to save your work.then wait until it finish saving it.
hope it will help.
