A JPEG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.

The compression used by JPEG encoders is "lossy", meaning image colours that are not perceptible to the human eye are discarded during the compression process. The removal of this colour data greatly reduces the size of the final JPEG file with no discernible loss in quality.

Due to their compact and high-quality format, JPEG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPEG files can be edited within most popular image editing software.
