JPEG is a lossy compression standard for digital images. The JPEG compression reduces some data, but the loss is almost unnoticeable to the human eye. Due to the small size of JPEG files, the format is widely used for storing and transferring images. JPEG is also used for taking pictures with digital cameras.

File extension

.jpg, .jpeg, .jfif, .jif, .jfi,.jpe

Technical details

The JPEG compression is based on the discrete cosine transform (DCT).
