ICO to MOBIPOCKET Books conversion is the process of transforming an ICO (Windows icon) image file into a MOBI (Mobipocket) eBook-compatible image container or embedded resource. This typically involves extracting the raster image from one or more icon frames, converting to a supported bitmap format and packaging or embedding it into a MOBI file so it can be displayed in Mobipocket-compatible readers.
