Images require generous capacity and transmission resources, accordingly image compression is worthwhile to diminish these prerequisites. This paper overlays some foundation of wavelet analysis, compression of data and how the wavelets are been and how it can be utilized for image compression. The paper analyzes an arrangement of wavelet functions (wavelets) for usage in a still image compression system and talks about critical highlights of wavelet change in compression of still images, including the degree to which the nature of image is corrupted by the procedure of wavelet compression and decompression. The impacts of various wavelet functions, image substance and compression proportions are surveyed.
