The Data Hiding in Your Photos
Every photo from a phone or camera carries a hidden layer of text called EXIF metadata. The camera writes it automatically at the moment of capture: the device make and model, the exact date and time, exposure settings like shutter speed and ISO, the editing software used, and, when location services were on, GPS coordinates precise enough to identify a building.
The format dates back to the 1990s, designed so cameras and printers could exchange technical details. Photographers still rely on it to study their settings, and photo apps use it to sort libraries by date and place. The data itself is useful, the surprise is that it travels invisibly with the file.
This tool reads all of it in your browser and lays it out plainly. If coordinates are present, a clear warning appears, because that single field is the one with real-world consequences.
