Bookbinder is a program that will convert a PDF document into signatures suitable for traditional bookbinding.
While there are a lot of programs on the net that will create a single booklet from a small document, I couldn’t find one that would turn a 500 page novel or textbook into several signatures. So I had to write one.

The chosen PDF is split into chunks, the page order of each chunk is rearranged, then the pages are placed two to a page in a new PDF. After printing and folding, each bundle of sheets should be a correctly ordered signature, ready for binding.
