Short for Joint Photographic Experts Group, JPEG is a digital image compression format, and one of the most popular image types shown on the Internet and used with digital camera. The JPEG standard uses a lossy sacrificed to achieve greater compression. JPEG is also abbreviated as JPG in the file extension used with IBM compatible computers. In the image to the right, is an example of a JPEG image.
What opens a jpeg or .jpg file?

Should I save my image or photo as a JPEG?
Deciding what image type to use when saving an image or photo depends on your requirements. If the image you're saving is a basic image with no gradients and not many colors (e.g., a logo or illustration) and you're concerned about file size we recommend using GIF. However, if you're working with a more complex image or photograph, we recommend saving it as a JPEG or PNG.
How big is a jpeg file, in bytes?
The size of a jpeg image file can range very widely. The dimensions of the jpeg image and the resolution of the image are the two biggest factors that determine the size of a jpeg file.
The larger the length and width of an image, the larger the image file size. The higher the resolution, increasing the quality of the image, the larger the image file size.
Today, jpeg image files can be tens or hundreds of MB (megabytes) in size, due to the increased quality of digital cameras and image editing software. However, it is possible to create very small jpeg image files, often called thumbnails, that can be as small as tens or hundreds of KB (kilobytes).
