PRIVACY GUIDE · WHAT TRAVELS WITH A PHOTO
What does photo metadata reveal?
A JPEG carries more than the picture. Cameras and phones record when and where a photo was taken, on what device, and sometimes who took it. Editing apps add their own notes. Most of it is invisible until you look for it.
The kinds of metadata in a JPEG
Metadata sits in separate blocks inside the file, alongside the image data. Each standard covers different information, and one photo can contain several.
| Type | What it can contain | In a cleaned copy |
|---|---|---|
| EXIF | Camera make and model, lens, exposure settings, date and time taken, GPS coordinates, serial numbers, editing software, a small preview thumbnail, orientation | Removed, except the orientation value needed to display the photo the right way up |
| XMP | Creator, editing history and software, ratings, keywords, sometimes location names | Removed |
| IPTC | Captions, creator and copyright, credit lines, location names | Removed |
| JPEG comments | Free text added by some apps and cameras | Removed |
| ICC colour profile | How the colours should be displayed, plus a profile description | Kept by default so colours look the same. You can remove it. |
| Data after the image | Bytes some apps append after the end of the image | Removed |
Location is the one to check first.
If location services were on for the camera app, EXIF can hold GPS latitude and longitude, often precise enough to pick out a single building. A photo taken at home and shared as a file can point straight back to the address. Altitude, compass direction and the GPS timestamp may be stored too.
The other details add up.
- Dates and times show when a photo was taken and edited, which can reveal routines.
- Camera serial numbers can link photos from the same device across different accounts.
- Creator and copyright fields may hold a real name set once in an app and forgotten.
- Embedded thumbnails are small previews stored in EXIF. If an app edits the photo without updating the thumbnail, the preview can still show the image as it was before, crop included.
Does the site you upload to remove it?
Some sites and apps remove metadata from public images on upload, and others keep it. Policies and settings change, and a photo sent as a file, an email attachment or a document usually arrives byte for byte. If location or identity matters, clean the copy you share rather than relying on where it’s going.
What metadata removal doesn’t cover
Cleaning removes hidden information. It doesn’t change what the photo shows. A street sign, a house number, a reflection or a face in the picture is still there. The filename can give things away too, as can the dates your computer stores for the file. Check those yourself before sharing.

Photo Privacy Check shows the location, camera, dates and author details in your JPEGs, then makes cleaned copies and checks them again. Your photos are processed in your browser and aren’t uploaded.
