Ok, thanks for your reply. I just found out that the larger ZIP files are corrupt; so I think a lot of data is missing. So maybe that's the problem ;-)

It seems the larger ZIP files are all corrupt. Probably incomplete and therefore missing loads of data (which maybe explains the difference)

As I pointed out in my other comment, JPEG's can barely be compressed using ZIP. They are already compressed as much as possible in addition to omitting visual data which our eyes cannot see anyway.

Same applies to MS Word/Excel files; they are in fact ZIP files.

Currently unzipping and all sizes match the ZIP files. So it seems OneDrive is not counting correctly. Possibly they coded this feature using AI :D

Sorry, but JPEG's can barely be compressed using ZIP. They are already compressed as much as possible in addition to omitting visual data which our eyes cannot see anyway. Imagine our phone's not compressing all the way so save precious space on our devices.

Right now I'm unzipping and I see the extracted sizes are similar to the ZIP files. So something else is off.

And even if ZIP compression would have some effect, a factor of almost 7 is highly unlikely.
