I need to make a powerpoint presentation for school. I was hoping to make it in Keynote and export as a powerpoint file. Im adding zero transitions, and no large file size graphics. When I export even a 3 slide presentation, I end up with like a 2mb file! how can I massively shrink this size? I've looked in prefrences, and everywhere else I can think of. It needs to be like 20 slides long, and must be a small file size. Am I forced to use powerpoint to keep the file small. I really want to use the crayon theme from Keynote. Please help. due on Tuesday.
