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 compression with little perceptible loss in image quality. JPEG images are commonly used for storing and transmitting photographic images on the World Wide Web. The format supports 8-bit grayscale and 24-bit color images. Due to its widespread support and relatively small file sizes, JPEG has become the de facto standard for sharing images online. However, the lossy compression means that repeated editing and saving of a JPEG image can degrade its quality over time. For images that require lossless compression or contain sharp lines and text, other formats like PNG or GIF are often preferred.
