What your photos reveal, and how to remove it
A photo taken on a phone usually records the exact coordinates of where you were standing. That travels with the file.
What is in there
EXIF is a block of tags attached to an image file, written by the camera. A typical phone photo carries:
- GPS coordinates — latitude and longitude, often to within a few metres, plus altitude
- Date and time the shutter fired, to the second
- Device make and model — the specific phone or camera
- Lens, aperture, shutter speed, ISO, focal length
- Orientation, which is why photos sometimes appear rotated in one app and not another
- Sometimes a software name, a copyright field, and an embedded thumbnail
You can see exactly what any of your own images carry with the EXIF viewer. It runs in your browser, so the file is not uploaded anywhere to be read.
Why it matters
The GPS tag is the one that matters. A photo of something innocuous, posted publicly, can carry the coordinates of a home, a school, or a workplace. The date stamp tells someone when you were there. Together they are a location history you did not mean to publish.
The device model is a weaker signal but a real one: it links photos posted under different names to the same camera.
"Doesn't the platform strip it?"
Usually, but not reliably enough to depend on:
- Most large social platforms do strip EXIF when they re-encode an upload.
- They do not all strip it on every path. Sending a photo as a file attachment in a chat app, rather than as an image, very often preserves it.
- Cloud storage links, email attachments, forums, marketplace listings and anything that serves the original file will pass it straight through.
- A platform stripping it protects viewers on that platform. It does nothing about the copy you emailed.
The only reliable place to remove it is before the file leaves your device.
How to remove it properly
Use the metadata remover. It rewrites the file's container to drop the EXIF, XMP and comment blocks, and leaves the compressed image data untouched — so there is no quality loss and the file does not grow.
That last point is worth dwelling on, because most tools get it wrong. The easy way to strip metadata is to decode the image and save it again, which silently puts the photo through another generation of lossy compression and frequently produces a larger file than the one you started with. If a metadata remover hands you back something bigger, that is what it did.
Two things are deliberately kept: the JFIF density block, because removing it confuses some older software, and the ICC colour profile, because dropping it visibly shifts the colours on wide-gamut images. Neither says anything about you.
Turning it off at the source
iPhone: Settings → Privacy & Security → Location Services → Camera → Never. Existing photos keep their tags; only new ones are affected.
Android: open the Camera app's settings and turn off "Location tags" or "Save location". The wording varies by manufacturer.
Also useful: when sharing from an iPhone, tap Options at the top of the share sheet and turn off Location. That strips the coordinates for that share only.
When you want to keep it
Metadata is not only a liability. Photographers use the copyright and artist fields to assert ownership, and the exposure data is genuinely useful for learning. If you want to set those fields rather than remove them, the metadata editor writes them back into the file.
A reasonable default
Strip metadata from anything going somewhere public. Keep it on your originals, where the date and location are the difference between a photo library you can search and a pile of files.
