In computing, JPEG is a commonly used method of compression for photographic images. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.
The file format known as 'JPEG Interchange Format' (JIF) is specified in Annex B of the standard. However, this "pure" file format is rarely used, primarily because of the difficulty of programming encoders and decoders that fully implement all aspects of the standard and because of certain shortcomings of the standard.
Image files that employ JPEG compression are commonly called "JPEG photos". Most image capture devices (such as digital cameras) and most image editing software programs that output "JPEG files" are actually creating a file in the JFIF and/or Exif format.
Strictly speaking, the JFIF and Exif standards are incompatible because they each specify that their header appears first. In practice, most JPEG files in Exif format contain a small JFIF header that precedes the Exif header. This allows older readers to correctly handle the older format JFIF header, while newer readers also decode the following Exif header.
If you have accidentally lost JPEG files and now need to get them back, the standard FAT maintenance utilities can be used for photo recovery. And specialized recovery utility can recover JPEG files which could not be accessed normally.
