Combine Scanned PDFs in Reverse Order

I was faced a lot of times with the following problem: I canned some  documents with my one sided scanner, put the backside into the feeder of the scanner (thus scanned the backsides in reverse order), and then [hugh]… I spent hours to  cut-copy-paste the PDF together again. Finally I found a really good solution:

  1. download the free version of pdftk from https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
  2. safe the front pages PDF document as frontpages.pdf
  3. safe the reversed order backpages of the PDF as backpages_in_reverse_order.pdf
  4. open a comand line promt (cmd.exe)
  5. pdftk A=frontpages.pdf B=backpages_in_reverse_order.pdf shuffle A Bend-1 output allpages_in_correc_order.pdf

You can also do other things with this tool, as e.g. sorting pages that have been scanned in the wrong order (e.g. from last page to the first page):
type:

  • pdftk last_to_front.pdf cat end-1 output front_to_last.pdf
