What is EXIF? A plain-English guide to camera metadata
EXIF is the invisible data your camera writes into every photo. Here's what it contains and why it matters.
EXIF (Exchangeable Image File Format) is a standardized set of tags that cameras and phones embed inside every JPEG, HEIC, or TIFF they produce. It records the camera's make and model, the exact settings used, the timestamp, and — if location services were on — GPS coordinates.
Whenever you share a photo, EXIF usually travels with it. Some platforms (Instagram, Facebook, X) strip it on upload; others (email attachments, direct downloads, Discord, iMessage attachments in Files) preserve it. That means the picture you texted a friend of your new apartment can carry the exact latitude and longitude of your front door.
EXIF is not evil — it's genuinely useful. It's what lets Lightroom sort your library by lens, or reminds you that you shot a portrait at f/1.4 and it turned out beautifully. But it's opt-out, not opt-in, and most people never realize it's there.
