Method and system for adaptive image compression using block characteristics are provided. For adaptive image compression, blocks in an image are quantized and compressed using a quantization table that was used in quantization of the blocks. An image compression system checks a block-characteristics quantization table corresponding to a specific block in the image to be compressed in order to quantize the specific block, and performs calculation using a value of a first element of the quantization table corresponding to a specific element of the specific block and a value of a second element of the checked block-characteristics quantization table corresponding to the specific element in order to quantize the specific element.
