How to split all pages of a PDF document in half at once?

Description:

I would like a feature that would convert scanned document that was printed as booklet back into PDF. Some documents I get only in format of printed booklet. When I scan it into computer it's in format of two pages on one, with pages without order for reading as normal pdf (first, second, before last, last...).

Solution:

To split all pages in half at once, we could open the PDF document, go to File > Print > choose Tile Large Pages then print to Foxit PhantomPDF Printer to generate a new PDF document.
