What your photos reveal: EXIF location and device data
The most sensitive thing in a photograph is usually not the picture. It is the coordinate pair recorded the instant the shutter fired, accurate to a few metres, sitting in the file where anyone who opens its properties can read it.
01What a phone writes into every photo
Latitude and longitude, often with altitude and compass heading. The exact date and time, down to the second, in local time and sometimes UTC. The make and model of the device, the lens, the software version. Exposure settings, focal length, whether the flash fired. On some devices, a unique serial number.
None of this requires a setting to be switched on. Location tagging is enabled by default on most phones, and the data is written silently at capture.
02Where it survives and where it does not
Most large social platforms strip EXIF when you upload, partly for privacy and partly to reduce file size. That protects you on those platforms specifically and nowhere else.
It survives almost everywhere else: email attachments, messaging apps that send files rather than compressed images, cloud storage links, forum uploads, marketplace listings, and any website that stores what you gave it. A house photographed for a rental listing can disclose its own address.
It also survives being sent to someone who then forwards it, because the data travels with the file rather than the conversation.
03Removing it
Re-encoding the image discards every metadata segment, because the new file is built from pixel values alone. This is what the image tool on this site does, in your browser, without the file being uploaded.
Operating systems offer their own routes. Windows exposes a Remove Properties option in a file's Details tab. macOS Preview can strip location through its inspector. Both work well for a single file and become tedious in bulk.
Disabling location tagging at the camera is better than removing it afterwards, because it prevents the data existing at all. On iOS this sits under Privacy and Security, Location Services, Camera. On Android it is a toggle inside the camera app's own settings.
Questions
Does sending a photo over WhatsApp or iMessage remove EXIF?
+
Usually yes for the compressed version these apps send by default, because recompression discards metadata. Sending the same image as a file or document attachment preserves it, and that option is often only one tap away.
Can location be worked out without EXIF?
+
Frequently, yes. Visible landmarks, street signs, reflections, window views and even vegetation can identify a place. Removing metadata removes what the file states, not what the photograph shows.
Does cropping a photo remove its metadata?
+
It depends entirely on the editor. Some rewrite the file and drop metadata; others preserve the original EXIF block deliberately so photographers keep their camera data. Never assume cropping is sufficient — check, or re-encode.
