Taking 2 A4 PDF files and creating 1 A3, with these two A4 files side by side

[If_you_don_t_ask___]

Using Adobe Acrobat 11 on an iMac running OSX 10.9.5

I have two A4 documents (as PDF files) which I want to combine into one A3 document and then export this one document as a PDF.  BUT, the two A4 documents MUST lie side by side so page 1 of document 1 lies alongside page 1 of document 2 and so on so as both these A4 documents correlate to each other line by line...

How do I do that???

Anyone got any help, ideas or suggestions?

Thanks guys!

On a Windows machine it can be easily done using the Adobe PDF printer, but that's not available on Macs.

So the alternative is to use a script, like this one I've developed, which you can purchase from here: Custom-made Adobe Scripts: Acrobat -- Print Multiple Pages Per Sheet
