Quick answer: EXIF is the metadata stored inside photos, recording details like camera model, exposure, date and often GPS location.
EXIF (Exchangeable Image File Format) explained
EXIF is the standard way cameras and phones record details about a photo inside the photo file itself. They write EXIF data into JPEG, HEIC and many RAW files. It records shutter speed, aperture, ISO, lens, orientation, time and, if location is on, where the photo was taken.
Photographers rely on it, but it can expose a home address or daily routine. On iPhone, the share sheet's Options menu lets you turn off Location for photos you share from there.
Before sending photos to strangers or posting them, remove EXIF location from the copies. Keep it for clients or collaborators who need camera details.
What EXIF typically contains
| Field | Example | Useful for |
|---|---|---|
| Camera make and model | The phone or camera name | Knowing which device took it |
| Date and time taken | The moment of the shot | Sorting photos in order |
| Exposure | 1/250 s, f/2.8, ISO 200 | Learning and editing |
| Focal length and lens | The lens used | Photographers' records |
| Orientation | Rotated 90 degrees | Showing the photo the right way up |
| GPS position | Latitude and longitude | Maps and travel albums, but also a privacy risk |
How to remove location from photos
- Per share on iPhone: in the share sheet, tap Options at the top and turn off Location.
- For a batch: run the copies through the remove image metadata tool before uploading.
- On Windows: select the photos, right-click, choose Properties > Details > Remove Properties and Personal Information, and create copies with properties removed.
- For the future: turn off location in your camera app's settings if you never want it saved.
Who keeps EXIF and who strips it
A download link and an email attachment deliver the photo unchanged, so all EXIF data, including location, goes with it. Many social networks and chat apps remove some or all EXIF when they re-compress photos, but you cannot always tell exactly what they keep. If location is sensitive, remove it yourself rather than relying on an app to do it.
Frequently asked questions
How do I see a photo's EXIF data?
On Windows, right-click and check Properties > Details. On a Mac, open it in Preview and use Tools > Show Inspector. On iPhone, swipe up on the photo.
Does a screenshot contain EXIF location?
Normally not, since screenshots are not taken by the camera.
Do HEIC photos have EXIF data?
Yes. HEIC photos carry the same kind of EXIF information as JPGs, including location if it was turned on.
Can I change the date in a photo's EXIF?
Yes. Many photo apps can adjust it, for example Image > Adjust Date and Time in Photos on a Mac.
