What is Metadata?
Understand the hidden language of your files: from Exif data in photography to ID3 tags in music and XMP fields in documents.
Simply put, metadata is "data about data." It provides essential information about other data, making it easier to find, track, and manage files. Whether it's a digital photo, a PDF document, or a music track, hidden tags describe its content and context.
Exif
The standard for storing camera settings (ISO, shutter speed) and GPS location in images.

Widely used by news agencies and photographers for copyright and captioning.
ID3
The container for MP3 metadata like artist, album, and cover art.
XMP
Adobe's Extensible Metadata Platform for embedding data across files.
