What do your photos hide?
Every phone photo carries invisible data called EXIF: the device model, the date and time to the second, camera settings and often the exact GPS coordinates where it was taken. If you send a photo of an item you sell from home, or of your children, as a file to a stranger or post it on a site that doesn’t strip this data, you may reveal your address without knowing it.
How to use the tool
- Drop one or more photos (up to 30) onto the box.
- For each photo, the tool shows what it found: location, date, device, serial number, owner name…
- Download each clean copy, or all of them in one ZIP.
- Use the clean copy when sending or posting.
Does it reduce quality?
Not in normal cases. For JPG, PNG and WebP we remove the metadata blocks directly from the file without re-compressing the image, so the pixels stay exactly the same and the file gets slightly smaller. The only exception: JPGs whose orientation depends on EXIF (a photo taken with the phone upside down) are redrawn upright at 95% quality so they don’t appear rotated once the data is gone. We also keep the colour profile (ICC) so colours don’t shift.
What gets removed?
| Type | Typical content |
|---|---|
| EXIF | GPS, date, device, lens, serial number, thumbnail |
| XMP | editing history from apps like Photoshop or Lightroom |
| IPTC | photographer name, keywords, captions |
| PNG comments and text | software name, author, any embedded text |
Privacy tips
- You can stop the camera from recording location in the first place, in your phone’s location permissions for the camera app.
- Some social networks strip EXIF automatically, but sending “as a file” or by email usually keeps it.
- Metadata isn’t the only risk: watch what appears in the background, and use the face blur tool to hide faces.
