It does use the same lossless compression as PNG-8 but you will obtain a larger file size due to the amount of information that will be retained vs. I managed to get it down to 88k by simply lowering resolution to 240×180 the size used in my Java app. Other settings are installed by default.

This can be done by extracting the alpha channel shrinking the transparency spectrum and stuffing it back into the image. Also for your convenience weve added the preview mask option.
