JPEG stands for Joint Photographic Experts Group. The JPEG file format was created by this group as a compression format for larger bitmap image files.
Files that contain the .jpeg file extension are used to store digital images and photographs in a compressed lossy file format. This means that while the JPEG file format allows for a smaller file size, there may be a loss to the quality of the image that was stored in the file.
The JPEG file format is often used for graphics that are published on the Web and to store pictures that have been taken by a user's digital camera. Oftentimes JPEG files are stored with the .jpg file extension rather than the full .jpeg file suffix.
