Compression software for Mac Office Suite

Just out of curiosity, why would you like to compress MS Office? It doesn't take more than 500MB or 1GB of HDD/SSD capacity away.

EDIT: I see what you mean now, you want to compress the actual resulting work files.

 

Some file types compress more than others. For example, a .doc file which is mostly text will compress a lot, whereas a file containing a movie, music or images, not so much. It's the embedded images in your PowerPoint files that aren't compressing much. There are things you can do, such as reducing the resolution or size of the images to make them smaller, but compression technology isn't going to get you very far with multimedia files.

 

If you're trying to get it down to size for e-mail or the like, you can always split your powerpoint presentation into parts, i.e. part 1/2/3 etc. then send one at a time.
