EXIF metadata
Also known as: EXIF data, photo metadata, image metadata
EXIF metadata is the information embedded inside a photo file describing how and where it was taken — camera model, exposure settings, date, time, and often GPS location. It is tiny in size but matters for privacy and for how photos are sorted and searched.
- Embedded data: camera, settings, date, and often GPS
- Tiny in size — not a storage concern
- Can be stripped before sharing for privacy
What EXIF stores
Most digital photos carry an EXIF block recording the camera or phone model, lens, shutter speed, aperture, ISO, and the exact date and time. Many also include GPS coordinates of where the shot was taken, which is what lets photo apps place pictures on a map.
This data is what powers features like “On This Day,” location albums, and search by place or camera. It is generally a few kilobytes — negligible next to the image itself — so it is not a storage problem.
Privacy and EXIF
Because EXIF can reveal where and when a photo was taken, it is worth knowing how it travels. iOS lets you strip location when sharing via the Options menu in the share sheet. Many messaging platforms also remove metadata automatically, but emailing or AirDropping an original file usually keeps it intact.
