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. ExifTool can also be used as a metadata removal tool for supported file types, except for PDF, as old metadata is never actually deleted. (However, after running ExifTool the old metadata may be removed permanently using the "qpdf" utility) It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application. ExifTool 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. ExifTool is incorporated into different types of digital workflows, and is often used in digital forensic analysis and library archival. It is recommended over online Exif sites when dealing with more sensitive tasks since it can be run locally. Another common use is removing sensitive metadata, like location data, from photos. The tool, as of 2021, is widely-used.
