Tip: Reordering pages when document was scanned as a booklet

Sometimes it's easier to scan a document as a booklet, removing the middle ligature and feeding all pages into a scanner at once.

The page ordering in the scanned PDF is not the natural one. To split the document and then reorder the page back to their natural order there's a handy option you can select: Repaginate from booklet scan

Example: You scanned a book by taking out the middle ligature clips and feeding the double pages into a scanner. In the scanned PDF, the pages are in the following order:
12, 1, 2, 11, 10, 3, 4, 9 and so forth, for a 12 pages document.
