Thirty seconds
EXIF (Exchangeable Image File Format) is a block of tags many still cameras and phones write into JPEG and some other formats. Typical fields: camera make and model, lens, shutter, ISO, the time the shutter fired, orientation. On phones, an optional GPS IFD may sit in the same envelope.
It lives in the file header, not in the visible picture. A screenshot of the photo is usually a new file with little or none of that envelope.
What a phone photo often contains
- Device make/model (“iPhone 15 Pro”, a Pixel name, a Samsung model).
- Capture time in the camera’s timezone handling — which may not match the album date you see in an app.
- Exposure and lens fields the camera app filled in.
- GPS only if location tagging was on and the OS actually wrote coordinates.
GPS is optional
People search “EXIF” when they mean “does this photo have my address.” Those are related, not identical. Coordinates, when present, are usually an EXIF GPS IFD, sometimes copied into XMP. Turning off Location Services, or exporting a sharing copy, is a different action from “delete all EXIF.”
Details: GPS metadata, geotagging, does removing EXIF remove GPS.
After you upload
Discord, Instagram, X, WhatsApp and similar apps frequently make a new compressed file. Some strip GPS. Some keep other EXIF. Some keep nothing useful. The behavior changes with product versions, “HD photo”, “original quality”, and “send as file.” Treat any list of platforms as perishable.
The original in Photos / Google Photos is still the one that may carry the envelope. Sending “original” or “as file” is the path that most often preserves it.
Look, then decide
Open the file in Metadata Cleaner and read the tags. If GPS is absent, the remaining risk is usually what is visible in the pixels, not a hidden coordinate. If you want a sharing copy without supported headers, export from the same tool. HEIC originals are not stripped here — export JPEG/PNG/WEBP first.
