In present paper, the authors proposed a simple and effective method to compress an image. Here, they found success in size reduction of an image without much compromising with it's quality. Here, they used Haar Wavelet Transform to transform their original image and after quantization and thresholding of DWT coefficients Run length coding and Huffman coding schemes have been used to encode the image. DWT is base for quite populate JPEG 2000 technique. IMAGE compression is the application of data compression on digital images.
