Abstract
An image compression method includes segmenting, by a processor, an image file to be compressed into a plurality of blocks; performing, by the processor, a first pixel conversion based on pixel difference values between blocks from among the plurality of blocks; and storing the image file of which the first pixel conversion is completed in a first format.
