What is JPEG?
JPEG is a very well supported file format and works with all modern web browsers. It does not include an opacity channel so there is no transparency.
It uses lossy or lossless compression for digital images and is best for saving photographs and paintings of realistic scenes with smooth variations of tone and color (where you do not notice the missing details).
JPEG works best for colour images. It is commonly used for digital camera images as it gives you high-quality images. One main feature of JPEG is that it enables you to choose between quality and file size; you can sacrifice quality for a smaller file or vice versa.
The file name extension for JPEG files are:
.jpg or .jpeg
