Compression rates of 10:1 or 20:1 yield little degradation in image quality. Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. The JPG format is often used in digital camera memory cards. The resultant 'lossy' file means that quality can never be recovered. JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved. They do not encode information that is specific to the application software, hardware, or operating system used to create or view the document.
