Both formats, briefly
JP2IN
JP2 is the JPEG 2000 container, and it works on wavelets rather than the small blocks of ordinary JPEG. It compresses either lossily or losslessly, blurs rather than blocks as quality drops, and can be decoded progressively or only for the region you asked for. Those properties made it standard in digital cinema packages, medical imaging systems, and satellite and mapping data. Browsers largely skipped it, so files usually need converting for general use.
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.
