Most phone cameras save the place where a photo was taken inside the file itself. Anyone who receives the original file can read it. Here is how that works and how to remove it.
Photos carry EXIF metadata: date and time, camera model, sometimes the exact GPS coordinates. Many social networks strip this when you upload, but e-mail attachments, cloud links, marketplace listings and messenger 'send as file' options often keep it.
A picture taken at home can reveal your address. Listings for items you sell, photos sent to strangers and pictures of children or your car are the typical cases where it is worth removing the data first.
Open GeoWipe, add the photo and download the clean copy. The tool re-saves the image without any metadata and tells you whether location data was found. Your original file stays unchanged.
You can also switch off location tagging in your phone's camera settings. Do both: the setting protects new photos, GeoWipe cleans the ones you already have.
