ExifTool

ExifTool is a powerful command-line application for reading, writing, and editing metadata in a vast array of file formats. It handles metadata—often called EXIF data—for images, audio, and video files. With support for hundreds of file types, it allows you to view hidden information like camera settings, GPS coordinates, and creation dates. You can also batch-edit this data, correct timestamps, remove personal information, or standardize metadata across entire collections, making it an indispensable utility for photographers, archivists, and digital asset managers.
