Content Credentials marker check

Reading the result
A marker is a clue, not a verified record
Content Credentials can be stored in different image formats. This quick check looks for supported signs of a record in the selected file.
A possible record is present
A full check is still needed to read the record, verify its signature and confirm who signed it.
No supported marker was found
The image may never have had a record, or a copy or export may have removed it. This says nothing by itself about AI use.
Keep the original if possible
An earlier file may contain details missing from a screenshot or shared copy.

Frequently Asked Questions
What is a Content Credentials marker?
It is a sign in the file structure that a Content Credentials record may be present. This tool does not read claims or validate signatures.
Why is this called a quick check?
It looks for supported markers in the file. A full Content Credentials check must also read the record, validate its link to the file and check the signer.
Does a detected marker guarantee the image is authentic?
No. A marker does not prove that the record is valid, that the signer is trusted or that the scene is real.
Why might an ordinary photo have no marker?
Many cameras do not add Content Credentials. Editing, exporting, sharing or taking a screenshot may also remove them. No marker is not an AI verdict.
