ExifTool is a platform-independent command-line application for reading, writing, and editing Meta information contained in a variety of visual, audio, and video files. ExifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the maker notes of many digital cameras by Canon, Casio, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony. Although ExifTool is not a validator, it often reports useful information in case of defective files.

Platform

The stand-alone Windows executable does not require Perl. Just download and un-zip the archive then double-click on "exiftool(-k).exe" to read the application documentation, drag-and-drop files and folders to view meta information, or rename to "exiftool.exe" for command-line use. Runs on all versions of Windows (including Windows 7).

Windows Executable: exiftool-9.82.zip (3.8 MB)

The OS X package installs the ExifTool command-line application and libraries in /usr/bin. After installing, type "exiftool" in a Terminal window to run exiftool and read the application documentation.

Mac OS X Package: ExifTool-9.82.dmg (2.4 MB)

Everyone else (Unix, etc): Don't worry, you should already have Perl installed.
