I have a PDF file that was the result of the scan of a book.
In this file 2 pages of the book correspond to 1 in the PDF. So when I see a page in the PDF file I'm actually seeing 2 pages of the book.
I would like to know if there's any way to convert this file to another PDF where 1 page of the book corresponds to 1 page of the PDF i.e. the normal situation.
