ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata. As such, ExifTool classes as a tag editor. It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application. ExifTool is commonly incorporated into different types of digital workflows[3][4][5][6] and supports many types of metadata including Exif, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the manufacturer-specific metadata formats of many digital cameras. This tool is often used in digital forensic analysis[7][8][9][10][11][12][13][14] and library archival.[15][16][17]

Metainformation encapsulation

[edit]

ExifTool also implements its own open metadata format. It is designed to encapsulate metainformation from many sources, in binary or textual form, and bundle it together with any type of file. It can either be a single file, wrapping existing data, added as a trailer on other file types, or used as a sidecar file, carrying for example Exif or XMP metadata.
