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

[FrancheMaisto]

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.

Turn on Spreads instead of Pages.

My feeling is it is better to set the default view in Acrobat after exporting so that readers have the ability to view according to their own preference.
