What is EXIF data, and what does a photo reveal?
Every photo your phone takes carries a small block of text you never see: when it was taken, on which device, with which settings, and very often exactly where.
Short answer: EXIF data is metadata that cameras and phones store inside a photo file. It usually includes the date and time, the device make and model, the camera settings and, if location was switched on, GPS coordinates that can point to a specific building. Anyone who gets the original file can read it.
What EXIF stands for
EXIF means Exchangeable Image File Format. It is a long-standing standard from the Japanese camera and electronics industry that defines how a camera writes information about a shot into the image file itself. It is not a separate file and it does not show up in the picture. It sits in a header at the start of the file, and any photo viewer, editor or website that knows where to look can read it.
EXIF is written by default by practically every smartphone and digital camera. You did not have to opt in, and most phones do not tell you it happens.
What a typical phone photo contains
The exact fields depend on the device and app, but these are the ones you will see most often:
| Field | Example | What it tells someone |
|---|---|---|
| Make and model | Apple iPhone 15, Samsung SM-S921B | Which phone or camera you own |
| Date and time taken | 2026:06:14 07:42:19 | When you were at that place, often with the time-zone offset |
| GPS latitude and longitude | 52.520008, 13.404954 | Where the photo was taken, often to within a few metres |
| GPS altitude and direction | 34 m, facing 210° | Which floor or which way the camera pointed |
| Camera settings | f/1.8, 1/120 s, ISO 64, 26 mm | Mostly harmless, useful to photographers |
| Lens | back triple camera 6.86mm f/1.78 | Which camera on the phone was used |
| Software | 17.5.1, Adobe Lightroom | Operating system version or editing app |
| Orientation | Rotate 90° CW | How viewers should rotate the image |
| Serial number, owner, artist | Body serial 0123456789 | Mostly on dedicated cameras; can link photos to one device or person |
| Thumbnail | Small preview image | A mini copy of the photo stored inside the file |
The location fields are the ones that matter. With a GPS fix outdoors, phone coordinates are often accurate enough to identify a single house. Paste them into any map and you see the street. Photos taken at home, at a child's school or at your workplace can quietly give those addresses away.
Metadata that is not technically EXIF
EXIF is the best-known block, but a photo can carry others alongside it:
- XMP: used by editing apps such as Lightroom and Photoshop. It can hold edit history, ratings, keywords and sometimes the original file name.
- IPTC: captions, credits, copyright and contact details, mostly added by photographers and news agencies.
- Maker notes: a manufacturer-specific section inside EXIF. Its contents are often undocumented and can include internal serial numbers or focus data.
- ICC colour profile: describes the colours. Harmless, but it is still extra data.
The embedded thumbnail deserves a special mention. Some older editing software updated the main image but left the original thumbnail untouched, so a cropped photo could still contain a small uncropped preview. It is rare with current apps, but it is one reason to remove metadata entirely rather than edit single fields.
Which file types carry it
- JPG: the classic carrier. Almost every camera JPG has EXIF.
- HEIC/HEIF: the default format on iPhones. Carries the same EXIF fields, including location.
- RAW formats (DNG, CR3, NEF, ARW…): very detailed EXIF and maker notes.
- PNG and WebP: can hold metadata, but usually carry much less. Screenshots are usually PNG and normally have no GPS position, though they may record a date or the device's software.
How to see the EXIF data in a photo
Windows
Right-click the file, choose Properties, then open the Details tab. Scroll down for camera, date and GPS sections. The same tab has a "Remove Properties and Personal Information" link, though it does not always remove every block.
Mac
Open the photo in Preview, choose Tools → Show Inspector, then the info tab. If the photo has location data there is a GPS tab with a map. In the Photos app, select a picture and press ⌘I.
iPhone
Open the photo in the Photos app and swipe up, or tap the ⓘ button. You will see the device, lens, settings and, if the photo has a location, a small map.
Android
In Google Photos or your phone's gallery app, open the picture and swipe up or tap the info/details icon. The panel shows the date, device, file size and a map if location was saved.
In your browser
Drop a JPG on Simple EXIF Remover. It reads the tags on your own device and lists the camera, date, software, serial or owner fields and GPS coordinates it finds, with a red "Location found" badge when the photo has a position. Nothing is uploaded, so it is a safe way to check a photo before you send it.
Is EXIF data a privacy risk?
It depends on who ends up with the original file. Many large social networks remove EXIF from the copies other people see (see which apps strip metadata and which keep it). Email attachments, cloud-storage links, messaging apps in "file" or "document" mode, forums and personal websites often pass the original along unchanged.
Realistic risks include:
- A marketplace listing photographed at home that reveals your address to strangers.
- Photos of children that show which school or playground they go to.
- A timestamp that contradicts where you said you were.
- A camera serial number that links an anonymous account to photos posted under your real name.
Most EXIF fields are harmless on their own. The location and the timestamp are the ones that turn a photo into a record of where you were and when.
How to remove it
You have three options, from most to least thorough:
- Strip everything before sharing. Simple EXIF Remover rebuilds the image from its pixels, so EXIF, XMP, IPTC, thumbnails and comments are all dropped, not just the fields shown on screen.
- Remove only the location on your phone. iPhone and many Android phones can leave out the location when you share. See how to remove location from photos on iPhone and Android.
- Stop recording it. Turn off location for the camera app so new photos never contain GPS data. You lose the map view in your own gallery, which some people want to keep.
Removing metadata does not remove what is in the picture. A street sign, a house number, a school logo or a distinctive view out of a window can still give away a location.
Frequently asked questions
Does every photo have EXIF data?
Almost every photo straight from a phone or camera does. Screenshots, images saved from social networks and pictures that have already been cleaned usually have little or none.
Can EXIF data be faked or edited?
Yes. EXIF is ordinary data inside the file and editing tools can change the date, camera or location. Treat it as a hint, not as proof of when or where a photo was taken.
Does a photo have location data if location services were off?
Normally no. Phones only write GPS coordinates when the camera app is allowed to use your location. Check a test photo: if no map or coordinates appear in its details, nothing was saved.
Is EXIF data the same as a photo's file name or date modified?
No. The file name and the date modified belong to the file system and change when you copy or rename the file. EXIF lives inside the image and travels with it wherever it goes.
