You need to have a look at ImageIO.write.

• The Java Tutorials: Writing/Saving an Image

If you want the result in the form of a byte[] array, you should use a ByteArrayOutputStream:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(yourImage, "bmp", baos);
baos.flush();
byte[] bytes = baos.toByteArray();
baos.close();
