I often come across PDF files with massive margins. And even though the actual content is reasonably small, I am not able to print 2 pages per sheet, because the margins take most of the page and the text becomes tiny.
Is there a way to trim the margins, i.e. get a new PDF file with smaller page size, such that each page is just a pre-defined area of the original pages (e.g. start at 1 cm from the top and from the left, and take 15 cm width and 20 cm height).
I am mainly after a solution working under Linux, but Windows-based answers are also welcome!
