Because it uses 1 bit per channel/color whereas the other file uses
8 bpc. The fact that their size ratio is less than 1:8 demonstrates
the lossy compression power of the algorithm used in the 8 bpc image.
kamaraju kusumanchi, the OP, might see differences between both files if
using a viewer that can zoom-in far enough that scan pixels of 1/600 inch
become larger than the screen pixels.
Have a nice day :)
