Pick any photo from your phone or camera. This page reads the hidden metadata inside it: often including the exact GPS coordinates where it was taken, the camera's serial number, and the moment it was shot. The photo never leaves your browser.
Most phones record the exact spot a photo was taken and write it into the file. That coordinate usually lands within a few metres of where you were standing: your home, your child's school, the hotel you are staying in tonight.
Large social platforms generally strip this when they re-encode your upload. That protection disappears the moment you send someone the original file: email attachments, messaging apps that send "as document", cloud links and AirDrop all preserve it intact.
Cameras also embed a body serial number. The same number appears in every photo that camera has ever taken, which links otherwise unrelated pictures to one device, and to whoever registered or sold it.
Checking takes a second. Removing it is CLOAK, one click away with the same pass.
Is my photo uploaded?
No. It is read inside this browser tab. Nothing is transmitted, stored or logged. You can verify that by opening your browser's network tab while you use it.
Which formats work?
JPEG files carry EXIF, which is where GPS and camera details live, so those give the fullest reading. PNG and WebP store metadata differently and usually carry less.
Nothing was found: am I safe?
It means this particular file carries no readable EXIF, which is good. Remember that metadata is only half the story: street signs, storefronts, window views and reflections identify a place perfectly well on their own.
Does screenshotting a photo remove the data?
Yes, a screenshot creates a new file with no original EXIF, but it also degrades the image, and the screenshot itself may record when and on what device it was taken.
