I just tried compressing a word file with size of 79MB( I converted a 100 Great Tips for the Amateur DSLR Photographer to a word document using AnyBizSoft PDF Converter) after conversion it become 6Mb that is around 91% reduction in size (I used strong compression, you can choose Strong, Standard or low. Or even you can choose a custom level.). The Images inside the document got some clarity loss but still not that bad.
