Remember tackling the apparently simple task of printing a folded booklet? Now is it page 1 on the left with page 7 on the right? And should the right side be printed upside down? Grrrr!
Booklet Creator is a free web service that allows you to upload a PDF file and have it converted to another PDF file that, when downloaded, can be printed as a book. That is, double sided with alternating pages.
There are some minor restrictions: the file can be only 10MB maximum and the document must be in portrait mode.
