wow, on the one hand...considering the people here we can fill in quite a few blanks, but on the other... do you mean from Illustrator or Photoshop? Though most do not refer to a photoshop file as a 'page' many do not from Illustrator as well...rather an illustration.
Either way, File then Save As.
That's a basic even in the 'dark side' of Windows....
Acrobat is only needed for editing and sophisticated creation of multi-media/interactivity.
