Every photo taken on a smartphone or digital camera contains hidden metadata called EXIF data. This includes information you would probably prefer to keep private — your exact GPS coordinates, the make and model of your device, the date and time the photo was taken, and sometimes even the altitude.
When you share a photo online, this data often travels with it. Anyone who downloads the image can extract your precise location using free tools. Here is how to check what your photos contain and how to remove it before sharing.
What EXIF Data Can Reveal
EXIF (Exchangeable Image File Format) is metadata embedded in image files by cameras and smartphones. A typical JPEG from a modern phone contains:
- GPS coordinates — latitude and longitude accurate to within a few metres
- Device information — make, model and sometimes serial number of your camera or phone
- Date and time — exactly when the photo was taken, including timezone
- Camera settings — shutter speed, aperture, ISO, focal length
- Software — which app or operating system was used to take or edit the photo
The GPS data is the most sensitive. If you photograph your home or workplace with location enabled, anyone who accesses that photo can find out where you live or work.
How to Check Your Photos First
Before removing anything, check what your photos actually contain. Our free EXIF Image Metadata Viewer lets you drop any image and see all embedded metadata instantly — including a map showing exactly where the photo was taken if GPS data is present. Everything runs in your browser — no image is uploaded to any server.
How to Remove EXIF Data
Windows
Right-click the image → Properties → Details tab → click "Remove Properties and Personal Information" at the bottom → choose "Remove the following properties from this file" → select all or choose specific fields → OK. This modifies the file in place.
macOS
Open the image in Preview → File → Export → the exported file will have reduced metadata depending on the format. For full stripping: use Image Capture or export as PNG which strips most EXIF. The most reliable method is: open in Preview, take a screenshot of the image (Cmd+Shift+4), and share the screenshot instead — screenshots strip all original metadata.
iPhone
Go to Settings → Privacy & Security → Location Services → Camera → set to "Never" or "Ask Next Time" to stop GPS being added to new photos. For existing photos, use the Photos app: open a photo → tap the info icon (ⓘ) → tap "Adjust" next to the location → tap "Remove Location".
Android
In the Google Photos app, open a photo → tap the three-dot menu → Details → tap the location to remove it. Alternatively, turn off "Save location" in your camera app settings before taking photos.
The Nuclear Option: Screenshot It
The simplest and most foolproof method: take a screenshot of the photo before sharing. Screenshots are fresh image files with no EXIF data from the original — they only contain metadata from the screenshotting process, which contains no GPS data and no device-identifying information from the original camera.
When Does It Matter?
EXIF data matters most when:
- You are posting photos of your home, workplace or regular locations publicly
- You are selling items online and photographing them at home
- You are sharing images with people you do not fully trust
- You are a journalist, activist or researcher who needs to protect sources
- You are posting travel photos before you have left a location
Social media platforms like Facebook, Instagram and Twitter strip EXIF data from uploaded images — so sharing via these platforms is generally safe. The risk is higher when sharing image files directly via email, messaging apps or file sharing services, where the original file with full metadata may be transferred intact.
Check Before You Share
Use our free EXIF Viewer to check any photo before sharing it. Drop the image in — no upload, no account, completely private — and see exactly what metadata it contains in seconds.
