** we all answered at almost the same time... too funny, but at least he's getting some anwers, eh??
PNG is lossless and up to full color.
JPG is usually lossy and either full color or grayscale only.
GIF is at best 256 palette but is lossless once color depth is dropped. GIF is inferior to PNG for everything except animated icons. If your seeing a loss with GIF its probably the lack of full color range. There should not be any option to set the compression rate for a GIF.
