JPG

From ColorWiki

JPG (or JPEG) is a file format (extension) for images which allows for compression of the file size.

The amount of compression can be adjusted to achieve a desired tradeoff between high quality and large file size - vs - low quality and small file size.

The jpg image coding standard also allows:

• An ICC profile to be embedded in the file
• Exif information to be coded into the file

The name "JPEG" stands for Joint Photographic Experts Group, the name of the committee that created the standard
