There are several tools that can n-up pdfs, like pdfjam, pdftk,...

How would I reverse the process, say, make a document of 2n pages from a document of n-pages?

If using a Java or .Net library is ok for you, you can use iText / iTextSharp.

An example for tiling an existing document can be found in the book iText in Action, 2nd edition, in the freely available chapter 6: / TilingHero.cs.

Otherwise PDF Scissors might be your friend.

Here is one of the possibilities. You can use pdftk multiple times to get the desired result.

1) Use pdftk to segregate your document into single page files.

 pdftk largefile.pdf burst

2) Merge the small files thus created in step 1 as per your requirement.

I know it is a clumsy process but should work for you.

EDIT: Please have a look at this project

It can solve your issue. (you can find the whole thread here:

This would not make 2 pages from 1, would it? – Jo So Nov 28 '12 at 11:47
It will separate 2 page document into 2 separate 1 page files. In general, If there are 2n pages in your original, this will create 2n separate 1 page files. Then you can stitch relevant pages together. – maths-help-seeker Nov 28 '12 at 17:07
@maths-help-seeker: you didn't "get" the problem of Jo So. He wants to split individual pages into multiple... (These files were once created to "save paper", in order to print 2 original pages onto one sheet of paper). – Kurt Pfeifle Nov 28 '12 at 17:39
please see my edit. It should work for his case. – maths-help-seeker Nov 28 '12 at 18:58
