Resizing individual pages within a PDF
I need help figuring out how to resize individual pages within a document. I am creating a new PDF by inserting individual PDFs into it to create one master document. Those individual PDFs come in different sizes: letter, legal, and executive. The final Master PDF needs to print 8.5 x 11 for all pages EXCEPT one page needs to print as legal (8.5 x 14).
When I insert the PDFs, they all print in their original sizes so the document comes out with all three pages sizes. I did figure out how to change the print settings so that the entire document prints as 8.5x11 (letter), but that doesn't solve my need for one page printed larger.
QUESTION: Does anyone know how to get the final result I am looking for?
I was thinking I could shrink the individual PDFs down to 8.5x11 before I insert them into the Master. And only leave the one page as 8.5x14. But the only options I find for that are in the Print Options, which doesn't actually change the size of the document. Any other ideas?
(Hopefully I explained this well enough. If needed, below is the version I am using.)
