How do I combine PDFs with preview to save paper?

When you go to print, select the Layout menu, you can pick 1, 2, 4, 6, 9, or 16 pages per sheet of paper.

 

I don't think that's what he's talking about. He's talking about combining pages that are already only a third full. Doing what you suggested will still leave a lot of blank space on each page, and will probably make what is there really hard to read because it will be so small.

Unfortunatley, I don't know a way to do what the OP is asking, but of course that doesn't mean there isn't one.

 

What software do you have?

 

Copy & Paste from preview into Text Edit / Word etc.

 

Easiest thing to do would be to crop the document down to a third of a page using Preview's Crop feature, then print 3 pages per page using the Print options. I think.

 

Unless it's actually an image. If it is an image, that won't work.
