That is difficult and depend on detailed knowledge of how the PNG
algorithms work (Their are a number of different styles)

A bigger decision is the PNG format.  If the sprites have a limited set
of colors a PNG 8 format may work better than normal PNG.

                    I wish that they would sell it.
                     It never does quite what I want,
                      Only what I tell it.
