JPEG is short for Joint Photographic Experts Group that is responsible for developing and maintaining the standards of compression algorithms for digital files.This group specifies the standard for the codec which defines compression and decompression techniques for various types of visual data compression.
Any graphical image produced by the set of standards given by this group is called a JPEG image.The file is created by selecting a compression quality from the range of algorithm suggested. While saving the image in this format, it is important to understand the trade-off between quality and size;the higher the quality the higher the size and hence an option has to be compromised upon.
The main disadvantages with JPEG compression is that transparency is lost.
