Create A4 PDF with Reduced Size PDF Contained Within

HI All,

I am looking to create A4 size pdf using various manfacturers datasheets.

The manufacturers datasheets are differerent sizes (letter, A4, A3 , other).

The final datasheet needs to be A4 size but with the original datasheet shrunk to a size (smaller than A4 with a blank space to allow headers and footer to be added, see example below.

Headers have been addded in this example, i do not want these to be added untill all relevat datasheet have been combined.

I'm looking to do this on several datasheets at once if possible, and if possible I would like to have these saved with the original filename adding "- Resized".

Can anyone hepl please?

Thanks,

Jamie
