Answer 3

What Is Jpeg Used For

Answer 4

JPEG is joint photographs experts group.
It is used to print stuff on the web.It is a far smaller file than the classic BITMAP image,and far greater quality.It cannot be edited,by itself,however.
In computing, JPEG (pronounced JAY-peg) is a commonly used standard method of lossy compression for photographic images. The file format 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.

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.

Answer 5

JPEG - Joint Picture Experts Group. This is a compressed image format. 1 to 6 defines the level of compression

Answer 7

BMP has a higher resolution than JPEG You might not notice for your picture, but with some pictures that you save from BMP to JPEG, the quality of the picture declines in order to save space.

Answer 9

Joint Photographic Experts Group (JPEG)

It's a way of reducing the size (kb/mb) of a photographic image, without greatly reducing the quality

Answer 10

A JPG (or rather JPEG) file is a "raster" -bitmap- type of image, i.e. it's not composed of vectors, but rather the information is stored in every pixel.

A good source of information is Wikipedia, using the following link:
