What is a JPEG File Type?
No technology existed in the early 1980s to allow users to easily compress and share digital images. In 1982, the JPEG working group began to design a compression standard that could be used to reduce the size of d'files, making them easier to share, while maintaining their quality as much as possible.
The JPEG file format was created by the working group in 1992. JPEG files are images created at the help of a loss compression algorithm that actually destroys some of the data contained in the original image file. This loss of data is most often invisible to the human eye. Because the JPEG standard continues to allow users to produce high-quality, shareable images, and because it is so integrated into the technologies used to create and share images, it is still the most widely used compression standard.
A JPEG file also contains metadata describing the contents of its file such as color space, color profile and information about the size of the image. The JPEG format image files are more often attached with the .JPG extension; with the .' extension .JPEG.
