ExifTool is a multi-platform and powerful library and command-line program combo designed to make it as simple and straightforward as possible to read and edit image, audio and video metadata information using your computer.
Once you've installed ExifTool on your Mac, you must open a Terminal window and type "exiftool" at the command line prompt to run exiftool and to get access to its built-in documentation.
Extensive support for a large array of meta information formats
ExifTool features extended support for the most popular multimedia metadata formats, such as IPTC, EXIF, JFIF, ID3 and many others.
Besides a wide variety of metadata formats, ExifTool will also enable you to work with a vast array of maker notes embedded by a large number of digital cameras from the most renowned producers worldwide (i.e. Canon, Nikon, Kodak, Sony, Pentax, Leica).
Vast collection of supported file formats
Moreover, ExifTool also includes support for reading, editing and creating a huge number of file formats (a detailed and comprehensive list can be found on the Supported File Formats page, on the developer's website).
To further simplify working with multimedia meta information, ExifTool makes it simple and fast to export info using a multitude of formatting types, from tab-delimited files to HTML, JSON and XML.
Fast and intuitive image content extraction
ExifTool also allows you to effortlessly extract image content from various RAW formats, thus making possible to quickly obtain thumbnails, previews and full-size JPEG pictures out of any collection of RAW photos.
Furthermore, while using ExifTool to manage your multimedia files' metadata, you will be able to rapidly process massive directories of files in an instant and with little to no effort on your part.
Support for a large variety of multimedia tag names
As an extra advantage, ExifTool can recognize and work with an impressive collection of tag names, therefore allowing you to focus on processing your multimedia content instead of worrying if the tools you work with support the media tagging formats you're using (a detailed list of all supported tags is available on the ExifTool Tag Names page).
