A portable record attached to a file
Content Credentials are based on the C2PA standard. They can describe where a file came from, which tools handled it and which edits were recorded. The information is cryptographically signed so compatible software can validate its provenance history.
Finding a C2PA carrier is different from validating its signature. Free AI Wiper reports supported carriers; it does not verify the signer or the credential's cryptographic validity. See how to verify a Content Credential for the separate validation step.
Different file formats carry this record differently. JPEG commonly uses APP11/JUMBF segments, PNG uses dedicated chunks, WebP uses RIFF chunks and MP4-family formats can use UUID boxes.
Are Content Credentials visible?
Usually not inside the picture itself. A compatible application or platform reads the file and decides how to present the information. Removing the portable record therefore does not visibly alter the image pixels.
What removal does not prove
Removing a Content Credential does not make an AI-generated file human-made. It also does not remove every possible pixel-domain watermark or prevent a platform from using its own detection systems.
Free AI Wiper reports the narrower, verifiable result: whether the supported portable record was found before cleaning and whether it remains afterward.
The C2PA explainer describes the standard and its limits. If you need to check your own file, use the image inspection guide; if a website's AI label persists, read why labels and file metadata can differ.
For video, the C2PA manifest is only one possible AI signal. An embedded watermark is a different technology.
