Last I checked, most .exe files weren't compressed, and jpeg images could frequently be compressed slightly further by good algorithms. Also, in the normal case for jSite, you're uploading a collection of files as a single freesite. In that case, what actually happens is that any smallish files get combined into one container (like a tar or zip file) and then encoded and compressed as a group. So if you have some html that compresses well, and some jpegs that compress a little bit, and some data that doesn't at all, then it will all be packed into one container and compressed together.
