That could work if you don't want to play with the files too much. What I sometimes do is:
GIMP: Reduce number of colors with "Posterize". Depending on the type of image, I reduce to between 8 and 64 colors. Save as PNG.
And then the magic command:
Code:
pngcrush -bit_depth 8 -force
to optimize the PNG compression, at the same time enforcing an 8-bit final file.
