How to print a 2pages file into a 1 page file

Hi guys, I have this portafolio with 2 pages composed as a magazine, ideally to visualize on issuu (so far all good). What I realize is that it would be good also have a version full page to send by email and ensure the people will see it ok (as soon as they open the pdf reader, avoiding to reset it to visualize 2 pages). 

it is possible to resize the page without loosing all the formating? or simple tell indesign to create a pdf printing 2 pages at the time?? the red mark is what I want to be 1 page.
