Unlike GIF which only uses 8-bit indexed color mode, APNG supports 24-bit color depth and many color modes, as PNG does. Although it is not an official PNG extension, it is backward compatible; meaning, an application that supports PNG (but not APNG), is still able to open the first frame of the APNG file.
