About ICO

Windows Icon

The Windows icon format, which packs several sizes of the same image, such as 16x16 and 32x32 pixels, into one file. Each size is stored as a bitmap or a PNG. Convert to ICO to make a favicon or a Windows application icon.

About JP2

JPEG 2000

A wavelet-based image format standardized in 2000, with lossy and lossless modes. It never caught on in web browsers, but digital cinema, medical imaging and map archives use it. Convert from JP2 to get a file ordinary apps can open; convert to it when an archive or imaging system requires it.
