I would like to know a preferably free software to compress PDFs on Win 7 so that I can email them. I came across this one, but it requested that I enable User Access Control so I am a bit wary..

Why not compress/archive them with something like winrar or 7zip? – Raystafarian Mar 31 '12 at 16:17

you can use PdfCreator to "print" it. you can define with how many dpi you print or with how many colors or if you want to convert the images to greyscale etc.
