What changes when you convert JPEG to ICO
- JPEG has no transparency, so the picture looks the same; the extra transparency support in ICO simply stays unused.
- JPEG is lossy and ICO is not. The conversion cannot bring back detail that JPEG 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.
