Hi guys! I'm a student and I use a scanner to take paper copies of handouts, etc. and turn them into PDFs. However, I only have a pretty cheap printer/scanner all in one, and while I can load dozens of pages at a time (thank god) it can only scan one side of double-sided documents. I can manually merge two PDFs, one with the front sides and one with the back sides, in preview, but this is extremely time consuming for many page documents. Is there any tool that can merge PDFs along a pattern something like "Take the first page of the first PDF and then the last page of the second PDF. Then the second page of the first followed by the second to last of the second..." so that I can automate this process? Or do any of you know a quicker way? Thanks! Note: I do have a windows side, so if any of you know software that works on Windows, that would also be fine.
