splitting pdf with pdftk I have a pdf document with an even number of pages, say 2n, and I would like to split it into n documents, say pages1_2.pdf, pages3_4.pdf, ....., pages2n-1_2n.pdf, each of which consists of 2 successive pages. More precisely, for any i in the interval {1..2n}, the i-th file should consist of page 2i-1 and page 2i of the original document.
pdftk does not seem to have a dedicated function but I think that with a for loop this could be achieved.
Could you please help me in writing the right script? Thank you in advance
There is an app called PDFsam. SAM stands for split and merge. There is a free Basic version of this app and you can set the pages to keep together. You can split every n pages.  It should do what you want without coding.
