JPEG (Joint Photographic Experts Group)

The JPEG file format is a popular image format most commonly used for the storage of digital photographs. The format implements a lossy-compression technology that allows for high levels of file compression with little perceptible loss of image quality, making it an ideal format for photographs.

This format is one of the most used on the internet today, with its small file sizes making it ideal for website images. Although there are newer image formats that may offer higher compression and quality, the JPEG is still an ideal format for digital photos.
