Understanding File Metadata and EXIF Data
File metadata, or meta data, is the "data about data"—a digital footprint embedded within your files. Standards like EXIF, IPTC, and XMP store this information. For images, EXIF data is particularly important, containing everything from camera settings to GPS coordinates. This meta data tells a detailed story about the file's origin and history.

While useful, this data can be sensitive. Every photo you take might contain precise GPS coordinates in its EXIF data. When you share that photo, you might be sharing your location. A good metadata viewer like this one helps you see exactly what information is attached to your files, giving you control over your privacy.
