EXIF Data Remover

Every photograph a phone or camera takes arrives with a block of metadata attached. The EXIF standard covers the technical fields — shutter speed, aperture, ISO, focal length, camera model — which are useful and harmless. What sits alongside them is the part worth thinking about.

GPS coordinates are the significant one. If location services were enabled, the file records where the picture was taken to within a few metres, along with the exact date and time. A photograph taken in your living room carries your home address in a form any software can read instantly.

There is more: device serial numbers that link separate photographs to the same camera, owner and copyright fields that some cameras populate automatically, editing history from certain applications, and on some devices an embedded thumbnail of the original — which occasionally survives cropping and shows what you cropped out.

Major social platforms strip metadata when you upload, so a photo posted to a public feed is usually clean. That creates a false sense of safety, because the places where photos most often leak location are the ones nobody thinks about.

Direct messages and chat apps frequently forward the original file. So do email attachments, links to cloud storage, uploads to forums and marketplace listings, images sent to a print service, and anything you host on your own site. Selling furniture online with photographs taken at home is the classic case: the listing is anonymous and the file is not.

The other overlooked route is professional. Photographs supplied to a client, a journalist, an insurer or a legal process carry whatever they carry, and the recipient can read it whether or not that was intended.

One EXIF field is doing real work: the orientation tag. Phone sensors are fixed, so when you rotate the phone the image is stored sideways and a tag records which way up it should be displayed.

Strip the metadata and that instruction disappears with it, so a photo that looked correct everywhere can suddenly appear rotated. Nothing has corrupted — the pixels were always sideways, and the note explaining that has been removed.

The fix is order of operations. Run the image through the Rotate tool first, using auto-orient to bake the correct orientation into the pixels, and then strip the metadata. After that the file needs no instruction, because it is stored the right way up.

The image is decoded to a canvas and re-encoded from those raw pixels. Canvas has no concept of metadata, so nothing carries across — the output contains the picture and nothing else. This is thorough by construction rather than by maintaining a list of fields to delete.

It happens entirely inside your browser, which matters given the purpose. Uploading a photograph to a server in order to remove its location data would rather defeat the exercise; here the file never leaves your device, and there is no copy anywhere holding the coordinates you were trying to remove.

Batches are handled the same way and returned as a single ZIP, which is the normal case when preparing a set of listing photographs or clearing a folder before sharing it.
