Merge Odd and Even Pages

Scanners without double-sided scanning give you the fronts and the backs separately. This puts the pages back in reading order.

How to merge odd and even pages

  1. Choose the PDF with the front sides and the PDF with the back sides (or one PDF with both).
  2. Tell the tool if the back sides are in reverse order (usual when you turn the stack over).
  3. Press Put pages in order and download.

Two ways to scan

  • Two PDFs: the front sides (pages 1, 3, 5…) and the back sides (pages 2, 4, 6…).
  • One PDF: all front sides first, then all back sides.
  • When you turn the whole stack over to scan the backs, the last back comes first: leave "reverse order" ticked. The page shows the new order before you start.

Good to know

  • If one side has a page more (an odd number of pages), it goes at the end.
  • Empty backs can be removed afterwards with Remove Blank Pages.
