JPEG (Joint Photographic Experts Group) is a widely used method of lossy compression for digital images, particularly for those produced by digital photography. The degree of compression can be adjusted, allowing a selectable trade-off between storage size and image quality. JPEG typically achieves 10:1 to 20:1 compression with little perceptible loss in image quality. JPEG images are commonly used on the web and in digital cameras due to their small file size and good image quality. However, repeated saving and editing of a JPEG image can lead to a gradual degradation of image quality due to the lossy compression algorithm. JPEG supports 8-bit grayscale and 24-bit color images. It is not well-suited for images containing sharp lines or text, where other formats like PNG or GIF may be more appropriate. The JPEG standard defines both a file format and a compression algorithm. The file format is often referred to as JPEG/JFIF, and it includes metadata such as camera settings and date/time information.
