A practical guide

Alternate Pages from Two PDFs: a worked example

  1. Choose exactly two PDFs: fronts first, backs second.
  2. Select the reverse-second-file mode if the backs are scanned backwards.
  3. Run the task, review the result and save it if needed.

Try this example

Fronts 1, 3, 5 and backwards-scanned backs 6, 4, 2 become 1, 2, 3, 4, 5, 6 when the second file is reversed.
