sig size

can someone help me…. i need to change the resolution of my sig… tot be smaller than 80 kb but keeping the quality…

Answer #1
I am confused…you want to change the “resolution” or the file size?
Answer #2
i belive that by changing the resolution the file size changes too
i want it to be smaller in both ways (resolution of a “standard” sig and size smaller than 80 kb but i want to keep the quality…)
