Both formats, briefly
BMPIN
BMP writes pixels to disk almost exactly as they are, with no compression to undo. Files get large quickly, which is why you rarely meet one on a web page, but nothing is approximated and any Windows program can read it. It shows up in older Windows software, in scanner and screen capture output, and wherever a tool wants raw pixel data with no decoding step. Convert to PNG to keep the same quality in a fraction of the space.
ICOOUT
ICO is the Windows icon container, and it is still what browsers look for at favicon.ico. A single file holds the same artwork at several sizes, commonly 16, 32, 48 and 256 pixels, so the system picks the right one for a browser tab, a taskbar or a desktop shortcut instead of scaling something badly. Build one when you are adding a favicon to a site or an icon to a Windows application.
