I have a 440k Word document on my Mac. When I open this in Pages and save it as a Pages document it becomes 1.7Mb. However, when I upload it to iWorks, it suddenly becomes 206Mb! I know that it automatically generates three versions - Word, Pages and PDF - but even so should still only be 2-3Mb total. Yet it's 100 times bigger! The same happens with other documents. Aside from the much-increased upload times, it also means that my iCloud storage isn't going to go very far. Anyone else experiencing this?
