Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications)[5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing encoding formats with the addition of specific metadata tags: JPEG lossy coding for compressed image files, TIFF Rev. 6.0 (RGB or YCbCr) for uncompressed image files, and RIFF WAV for audio files (linear PCM or ITU-T G.711 μ-law PCM for uncompressed audio data, and IMA-ADPCM for compressed audio data).[6] It does not support JPEG 2000 or GIF encoded images.
This standard consists of the Exif image file specification and the Exif audio file specification.
