Getting your tool ready…
Does cleaning remove every hidden signal?
Only declared supported fields/containers are inspected and cleaned. Hidden content and perceptual watermarks are not proven absent.
Does finding C2PA prove AI origin?
Metadata labels can be changed. This does not prove authorship or AI origin.
Why does a report still contain private metadata?
Comparison reports contain original metadata. Do not share sensitive values.
