Question

I have several A4 PDF documents which I would like (two into one) ‘glue’ together into A3 format PDF document. So I will get from 2PDFs A4 a single one sided PDF A3. I have found the excellent utility PDFToolkit and some others but none of them can be used to ‘glue’ side by side two documents.

Answer 1

Found the following (free and open-source) tool for doing Imposition called Impose (thanks danio for the tip). This solved my problem perfectly.

EDIT: Here is how it’s done:

Use PDF Toolkit to joint two PDF files into one (two A4)

pdftk File1.pdf File2.pdf cat output OutputFile.pdf 

Create from this a single page (one A3):

java -cp Multivalent.jar tool.pdf.Impose -dim 2x1 -verbose -paper-size '42.2x29.9cm' -layout '1,2' OutputFile.pdf
