Who likes convenience and better compression ratios should look at FILEminimizer from balesio.com/fileminimizersuite
It reduces the size of your PowerPoint and other Office files by 50-90% with one click and if you wish directly before sending out via email.
Free trial on the website.
This idea to reduce a presentation linked to XL 2010 made no difference. Perhaps it only helps if you have photos in slides not charts. Nothing reduces chart sizes not even breaking the links to XL.
Perfect - this reduced my PowerPoint file (rich in images) down to under a quarter of the size.
That is easy for a way to compressed, It's working clearly
