What is metadata?
Metadata is information stored about a file in addition to its main visible or audible content. Depending on the format, it can include author names, device details, timestamps, GPS coordinates, comments, artwork or workflow properties.
Browse metadata toolsCan photos reveal where they were taken?
Yes, when GPS coordinates are stored in supported EXIF metadata. A photo can also reveal location visually through landmarks, signs or addresses, so metadata cleanup and visual review are separate privacy steps.
Check photo locationCan MP3 files contain hidden information?
MP3 files can carry tag data such as title, artist, album, comments and embedded artwork separately from the audio stream. Some files can also contain more than one metadata structure.
