A practical guide

Get the page order right, then keep going.

  1. Choose your PDFs and arrange their file order.
  2. Use Append files, or choose Alternate PDF Pages for two scanned sides.
  3. Convert, inspect the sequence and download or reuse the result.

Try this example

Front scans 1, 3, 5 and back scans 2, 4, 6 can become 1, 2, 3, 4, 5, 6. If the backs were scanned 6, 4, 2, choose the reverse-second-file mode.

Before

  • Fronts: 1, 3, 5
  • Backs: 6, 4, 2

After · one PDF

  • 1
  • 2
  • 3
  • 4
  • 5
  • 6
Alternate PDF Pages with the second file reversed restores the scan sequence. Illustrative example.

Before you start: This example uses Alternate PDF Pages and exactly two files. Ordinary merging appends complete files.
