What changes when you convert JPG to ICO

- JPG is lossy and ICO is not. The conversion cannot bring back detail that JPG already discarded, so the file can grow without looking better.
- Expect a larger file with ICO; it trades size for quality or features.
- The icon file contains several sizes (from 16 to 256 px) so it works as a favicon and as a Windows icon.
