- Description
- A JPEG file is an image saved in a compressed graphic format standardized by the Joint Photographic Experts Group (JPEG). It supports up to 24-bit color and is compressed using lossy compression, which may noticeably reduce the image quality if high amounts of compression are used. JPEG files are commonly used for storing digital photos and web graphics.

‘JPEG’ is an acronym for Joint Photographic Experts Group, which created the standard in 1992. It is a commonly used method of irreversible compression for digital images, particularly those produced by digital photography. The degree of compression is adjustable, allowing a selectable tradeoff between storage size and image quality.
JPEG generally achieves 10:1 compression with little detectable loss in image quality. It is the most widely used image compression standard in the world as well as the most widely used digital image format, with several billion JPEG images produced every day as of 2015.
JPEG uses a lossy image compression technique, the discrete cosine transform (DCT), that was first proposed by Nasir Ahmed in 1972. Ahmed developed a practical DCT algorithm with T. Natarajan of Kansas State University and K. R. Rao of the University of Texas.
JPEG was largely responsible for the digital images and digital photos across the Internet and later, social media. The lossy compression in JPEG images was used in several image file formats. JPEG is the most popular image format used by digital cameras and other photographic image capture devices. Also, JPEG is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are more or less the same and are simply called JPEG. JPEG files usually have a filename extension of .jpg or .jpeg.
