Selling Online: The Metadata Your Marketplace Photos Leak

29 September 2026

You photographed that sofa with your phone, listed it on a marketplace, and a stranger now knows roughly where you live. Not because the platform told them, but because of what was inside the image file you uploaded. Whether that happens depends on the platform, the app version, and one setting on your phone. Here is the actual picture for the big marketplaces, and how to list safely without thinking about it each time.

What a photo carries before you upload it

A photo taken with a phone camera typically embeds EXIF data including GPS coordinates accurate to a few metres, the date and time, the device model, and in many cases the serial number of the camera module. You can read about what your camera serial number reveals, and it is more than most people assume. Photos taken indoors add a further problem we covered in why photos taken at home reveal more than photos taken outside: the background itself. A listing photo of a watch on your kitchen counter shows your window layout, your door type, sometimes a reflected street view. Metadata is the invisible leak; the image content is the visible one.

What the platforms actually do

Facebook Marketplace strips EXIF including GPS on upload, and has for years. It does not always strip metadata from images sent through Messenger, which is a different code path entirely. eBay strips EXIF from listing photos. Dubizzle strips GPS from uploaded images. Craigslist historically stripped it. Gumtree strips it. So does Vinted and Depop. The pattern is broadly good, but relying on it has three failure modes.

The one setting that fixes it at the source

On iPhone, go to Settings, Privacy, Location Services, Camera, and set it to Never. On Android, open the Camera app settings and turn off location tags or remove location permission from the camera. From then on, new photos contain no GPS data at all, and it no longer matters which platform strips what. Photos already taken keep their GPS until removed. To clean existing photos before listing, you can use our tool on this site: drop the images in, confirm the metadata is gone, download the clean copies, and list with those. Because the tool runs entirely in your browser, the files are never uploaded anywhere, which matters when the photos are of valuables inside your home.

Practical selling checklist

Why the file name matters more than people think

Even with EXIF gone, the file name often survives the platform upload. Phone cameras embed the capture timestamp by default, and some gallery apps append the album or place name if location tagging was on when the photo was taken. A file named at 02:00 plus a serial number in the EXIF that matches your other listings lets a persistent observer build a pattern: what you sell, when you post, and roughly where you are. Scammers use exactly this pattern to profile sellers who look like they hold stock at home, then arrange a viewing with a fake buyer. Rename files to something neutral before you list.

Selling online is safe when the only thing a buyer learns from your listing is the item. A one-time settings change plus a metadata check on older photos gets you there, and it costs nothing. Open the tool, drop in your next batch of listing photos, and see for yourself what disappears.
