Yesterday, using Calibre 1.18 (Windows 8, 64bit), I converted an epub with 336kb and the final filesize was these:

mobi: 405kb
azw3: 3465kb



Anybody knows what happened here? Could be there something on converting parameters that I use that outputs this huge amount of data?

By the way, the book is just text, with very little pictures. I can uploaded it here if it helps (it's in public domain).

Thanks.
Regards.
