JPEG, shortened to JPG, is an abbreviation of the acronym Joint Photographic Experts Group. A JPG is a digital image file format characterized by small file size due to lossy compression.
The JPG file format provides a potential for a very high level of file-size compression, making it an ideal option for web-based digital images and photos. This compression makes it an ill-suited option for print-based media where input quality is a prime concern in determining the output quality.
JPG Compression Examples:In the example image above take note of the level of digital artifacting occurring near the text, particularly at higher compression rates. Note also that the example image exists in a PNG format, as it is a lossless image format.
