PRIVACY GUIDE · VISIBLE DETAILS

What a photo can reveal even without metadata

Removing EXIF and GPS data takes away the hidden information in a file. It doesn't change what the picture shows. Before you share a photo of your home, your desk or your screen, it's worth a thirty-second look for the details people tend to miss.

Metadata is only half of it.

Metadata cleaning deals with what's stored alongside the image: location, camera, dates, names. Everything in the pixels stays exactly as it is. That's the point of a lossless clean, and it's also its limit. A cleaned photo of your front door with the house number in view still shows the house number.

A checklist for the picture itself

Hiding something properly

If you need to hide part of a photo, cover it with a solid, opaque shape. Blurring and pixelation are weaker: light blurring can leave text readable, and patterns such as numbers can sometimes be guessed back from a pixelated version.

Then check that the editor actually removed the hidden part from the file. In 2023, researchers disclosed a bug known as aCropalypse in the Markup screenshot editor on Google Pixel phones, and a related one in Windows' Snipping Tool. Cropped or edited screenshots could keep leftover data from the original image, so parts of the uncropped picture could be recovered. Both were fixed by updates, but the lesson stands: keep your apps updated, and when it really matters, export the edited image as a new file rather than overwriting the original.

Crop, cover, then clean.

Crop out what isn't needed, cover anything sensitive that must stay in frame, export a fresh copy, then remove the metadata from that copy. Cleaning last means the location and camera details from the original don't come along.

Don't forget the filename.

A file called IMG_4821.jpg says little. One called smith-family-new-house-maple-st.jpg says a lot. Filenames travel with photos sent as files and attachments. Rename the copy before sharing if the name gives something away.

Context can identify a photo, too.

The text around a photo, such as a caption, a tagged location or a reply that mentions a neighbourhood, can matter as much as the picture. So can combining photos: a view from one, a street sign in another and the time of a third can add up to an address even if none reveals it alone.

What metadata cleaning does cover

For the hidden part, a metadata remover takes away GPS coordinates, camera make and serial numbers, dates, author names and editing history. It should also remove embedded thumbnails, which can show an older, uncropped version of the photo. What each kind of metadata holds · Stop your phone saving location.

Clean the copy you share

Photo Privacy Check removes location, camera, date and author metadata from JPEGs without recompressing them, then checks each copy again before download. It runs in your browser. It can't see or change what's visible in the photo, so use the checklist above for that.
