I was looking at the ImageConverter class, trying to figure out how to convert a BufferedImage to 8-bit color, but I have no idea how I would do this. I was also searching around the internet and I could find no simple answer, they were all talking about 8 bit grayscale images. I simply want to convert the colors of an image to 8 bit... nothing else, no resizing no nothing. Does anyone mind telling me how to do this.

You can use JAI (Java Advanced Imaging), the official Sun (now Oracle) image library to do that.

The ColorQuantizerDescriptor shows the choice of quantization processes you can apply.
