JPEG is an image compression standard that was developed by the Joint Photographic Experts Group committee in 1992 for the storage and transmission of a wide variety of still graphics image formats. It is designed for compressing either full-color or gray-scale digital images of continuous-tone quality.

| - JPEG is an image compression standard that was developed by the Joint Photographic Experts Group committee in 1992 for the storage and transmission of a wide variety of still graphics image formats. It is designed for compressing either full-color or gray-scale digital images of continuous-tone quality.
- The name stands for Joint Photographic Experts Group. JPEG itself specifies only how an image is transformed into a stream of bytes, but not how those bytes are encapsulated in any particular storage medium. A further standard, created by the Independent JPEG Group, called JFIF (JPEG File Interchange Format) specifies how to produce a file suitable for computer storage and transmission (such as over the Internet) from a JPEG stream. In common usage, when one speaks of a "JPEG file" one generally means a JFIF file, or sometimes an Exif JPEG file. There are, however, other JPEG-based file formats, such as JNG, and the TIFF format can carry JPEG data as well.
- JPEG (Joint Photographic Experts Group) is a commonly used method of lossy 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. The MIME media type for JPEG is image/jpeg (defined in RFC 1341). The file extension is .jpeg or simply .jpg.
- In computing, JPEG is a commonly used standard method of compressing photographic images. The which employs this compression is commonly also called JPEG; the most common file extensions for this format are .jpeg, .jfif, .jpg, .JPG, or .JPE although .jpg is the most common on all platforms. The MIME media type for JFIF is image/jpeg (defined in RFC 1341).

| abstract
| - The name stands for Joint Photographic Experts Group. JPEG itself specifies only how an image is transformed into a stream of bytes, but not how those bytes are encapsulated in any particular storage medium. A further standard, created by the Independent JPEG Group, called JFIF (JPEG File Interchange Format) specifies how to produce a file suitable for computer storage and transmission (such as over the Internet) from a JPEG stream. In common usage, when one speaks of a "JPEG file" one generally means a JFIF file, or sometimes an Exif JPEG file. There are, however, other JPEG-based file formats, such as JNG, and the TIFF format can carry JPEG data as well. JPEG/JFIF is the format most used for storing and transmitting photographs on the World Wide Web. For this application, it is preferred to formats such as GIF, which has a limit of 256 distinct colors that is insufficient for colour photographs, and PNG, which produces much larger image files for this type of image. It is not as well suited for line drawings and other textual or iconic graphics because its compression method performs badly on these types of images, for which the PNG and GIF formats are more commonly used. The MIME media type for JPEG is image/jpeg (defined in RFC 1341).

- JPEG (Joint Photographic Experts Group) is a commonly used method of lossy 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 MIME media type for JPEG is image/jpeg (defined in RFC 1341). JPEG may not be as well suited for line drawings and other textual or iconic graphics, where the sharp contrasts between adjacent pixels can cause noticeable artifacts. Such images may be better saved in a lossless graphics format such as TIFF, GIF, or PNG. The file extension is .jpeg or simply .jpg.
