Discovering the Unspoken in Your Photos

ExifTool is a command-line application developed by Phil Harvey that allows users to find the metadata of various types of digital files, with a primary focus on image files.

However, ExifTool can handle a wide range of metadata formats found in various file types, including images (JPEG, TIFF, PNG, etc.), audio files (MP3, WAV, etc.), video files (MP4, AVI, etc.), and more.
