IPTC, International Press and Telecommunications Council Standards, was created for exchanging different types of information associated with images.
IPTC is not a file format. In TIFF and EXIF-TIFF files the IPTC data can be stored in a separate TIFF tag IPTC_NAA (id = 33723), or within Adobe Photoshop Resources (id = 34377). In JPEG and EXIF-JPEG files the IPTC data is stored in Adobe Photoshop APP13 marker segment.
See TIFF Non-Image Data Structure, JPEG Non-Image Data Structure, Photoshop Image Resource metadata structure.
