Meaning – The term JPEG, refers to a standard format for storing compressed true-color images. JPEG represents the Joint Photographic Experts Group, which is the name of the committee that developed this standard format.
The 16 million possible colors in a JPEG image are produced by using 8 bits for each color (red, green, and blue) in the RGB color space.
While the JPEG format is great for storing digital photos, it does have some drawbacks. The lossy compression can cause an issue called “artifacting,” in which parts of the image become noticeably blocky.
The JPEG compression algorithm may reduce the file size of a bitmap (BMP) image by ten times with almost no degradation in quality. Still, the compression algorithm is lossy, meaning some image quality is lost during the compression process.
Example of usage – “JPEG files may also include metadata that describes the contents of the file. This includes the image dimensions, color space, and color profile information, as well as EXIF data.”
