Overlay two PDF files with many pages

[krajnct]

Hi!

I have two PDF files with 67 pages each. In one file are pictures in the other is text (ready for printing a book). I wold like to overlay both files to get one file of 67 pages so that the page one of the first file and page one of the second file are overlaid and second page of the first is overlaid with the second page of the second file... and so on.
I hope that you understand what I need even when it's really hard for me to write it in English.

Thank you for your answer.
T.

Do you have InDesign?

Placing the PDFs on top of each other in InDesign would take only a few minutes.

You can do this in Automator (which you've already got on your Mac, so it's free).

Open Automator then drag options from the sidebar to create the workflow shown here. Make sure to select the circled option (Shuffling pages) to get the combination you're after. Add the two files you've got to the top list, then press the Play button and your file will be saved to the desktop (with an auto-generated name that isn't very helpful).
