Most people share photos without knowing what information the file carries beyond the visible pixels. A photo taken on a smartphone often contains the exact GPS coordinates of where it was shot, the capture time down to the second, the camera model, and the software version. None of this appears when you look at the photo. This guide shows you how to check what any photo file contains before you share it.
What hidden metadata looks like
Image metadata is stored in structured blocks appended to the image file. The most common standard is EXIF (Exchangeable Image File Format), which defines specific field names for technical and geographic data. A typical iPhone photo might contain:
- GPSLatitude: 37.7749 (a precise coordinate)
- GPSLongitude: -122.4194
- GPSAltitude: 52 meters
- DateTimeOriginal: 2026:03:14 09:22:11
- Make: Apple
- Model: iPhone 16 Pro
- Software: 18.3.1
- FocalLength: 6.86 mm
- ISOSpeedRatings: 125
The GPS coordinates can be entered into any mapping application to show the exact location where the photo was taken. The date and time can be cross-referenced with other information to reconstruct someone's schedule. The device model can be used to narrow down the identity of the photographer when combined with other data.
Checking metadata on macOS
On a Mac, the easiest way is through Preview or the Finder:
- Preview:Open the photo, then go to Tools > Show Inspector (or press Cmd+I). Click the GPS tab to see coordinates, the EXIF tab for camera data, and the TIFF/General tabs for additional fields.
- Finder Get Info: Right-click the file and choose Get Info. Expand the "More Info" section to see basic EXIF fields. GPS coordinates appear here if present.
- Photos app: Open the photo and press Cmd+I to see location and date information in the info panel.
Checking metadata on Windows
On Windows, right-click the image file and choose Properties, then click the Details tab. This shows GPS latitude and longitude, camera make and model, capture date, and other EXIF fields that Windows reads from the file.
The Details tab does not show all possible metadata fields. For a more complete view, third-party tools or a browser-based reader give more thorough results.
Checking metadata on iPhone
In the Photos app, open a photo and swipe up (or tap the info icon) to see the map location, date, time, camera, and aperture information. This shows the most relevant EXIF fields in a readable format.
The Files app does not display metadata. Third-party apps like Exif Metadata or Photo Investigator provide more detail if you need to inspect all fields.
Using PhotoTools to check metadata
The EXIF reader in PhotoTools runs in your browser and shows all readable metadata fields from an image file without uploading it to a server. Drop in any JPEG or HEIC file and the tool displays the fields it finds — GPS coordinates, capture time, camera model, and others — before you decide whether to strip them.
This is useful for checking a photo before sharing and for verifying that a previously cleaned file is actually clean. Drop in the file, confirm that GPS and other sensitive fields are absent, and proceed.
Fields that matter most for privacy
When reviewing a photo's metadata before sharing, prioritize these fields:
- GPSLatitude / GPSLongitude — the highest-risk fields. Reveal the exact location where the photo was taken.
- DateTimeOriginal — can establish where you were at a specific time or reveal daily patterns over a series of photos.
- Make / Model — identifies the device. Less sensitive alone but can be identifying when combined with other public information.
- Software — reveals OS or app version. Generally low risk but unnecessary for public photos.
Technical fields like focal length, aperture, ISO, shutter speed, and white balance are generally not sensitive for privacy purposes, though they can help identify a specific camera when combined with other information.
After finding metadata: what to do
If you find GPS coordinates or other sensitive fields in a photo you plan to share, the options are:
- Strip the metadata using the Remove EXIF toolbefore sharing. This produces a clean copy with no metadata. The original in your library is unchanged.
- Use the iOS share sheet option (iOS 15+): when sharing via the share sheet, tap Options and disable Location. This works for standard share actions but not for all sharing paths.
- Disable GPS for future photosvia Settings > Privacy & Security > Location Services > Camera > Never. This does not affect existing photos.
Always verify the file after cleaning by dropping it back into a metadata reader and confirming the sensitive fields are absent. The most common mistake is cleaning one copy and then inadvertently sharing the original.
Frequently asked questions
How do I check what metadata a photo contains?
On Mac, open it in Preview and press Cmd+I; on Windows, right-click → Properties → Details; on iPhone, open the photo and swipe up. To see every readable field without uploading the file, drop it into a browser-based EXIF reader.
How do I see the GPS coordinates in a photo?
Look for the GPSLatitude and GPSLongitude fields in any metadata viewer. If present, they pinpoint exactly where the photo was taken and can be pasted straight into a map.
Can I check photo metadata without uploading the file?
Yes. A browser-based EXIF reader parses the file locally on your device, so you can inspect GPS, timestamps, and camera fields without sending the photo to any server.
Which metadata fields are most sensitive?
GPS coordinates are the highest risk, followed by DateTimeOriginal (which can reveal where you were and when). Camera make/model and software are lower risk but unnecessary for public photos.
