What is a JPG file?
We call Joint Photographic Experts Group files JPG or JPEG files. These file formats offer an easy file storage solution for web-based graphics and images.
JPEG files operate in a compressed image file format that is easily rendered on website pages and in email messages. These compressed files contain allocation tables that tell computers where to read and decode each pixel in an image or graphic.
Many people use JPG files because of their high compression ratio of 10:1 for rendering stored graphics and images.

The JPG file format compresses files into small blocks of pixels that are easily readable by a wide variety of computer programs.

JPEG file Alternatives
People looking for JPG file alternatives often look to GIF file types as an easy alternative.
A GIF file is an alternate format that can be used to archive photos. A GIF consists of a series of pictures stored as a unit, with each picture occupying one byte in memory. This makes it much smaller than a JPEG file, which can contain up to 8 megabytes of data.
Because graphics processors can process and display GIF files more quickly than they can handle JPEGs, they are sometimes used for logos or graphics on web pages instead of images.
