What is a Content Credentials verifier?
Supported review flow
Check images, PDFs, videos and visible page media where C2PA data is available.
Clear statuses
Use Trusted, Signed but untrusted, Invalid and No credentials consistently across file and page reviews.
Responsible wording
Content Credentials provide provenance and integrity signals, not a final decision on truth.
How a verification session works
- Open the ProvSeal popup from the browser toolbar.
- Drop a supported file or run a current-page scan.
- Read the status badge and open the report for details.
- Use report data for internal review, editorial checks or provenance documentation.
Four verification outcomes explained
Supported formats
Verification: JPEG, PNG, PDF, MP4, MOV, WebM.
Test signing: JPEG, PNG, PDF.
Local vs ProvSeal backend upload
ProvSeal verifies locally in Chrome. This reduces data exposure for sensitive editorial, legal and brand assets compared to cloud-only verifiers.
Manifest
Declared actions, ingredients, claim generator, timestamps and binding to file bytes.
Signature
Cryptographic proof that manifest content was signed by a specific key.
Certificate chain
X.509 issuer, subject, validity and trust evaluation. See trust chains docs.
Not AI detection
Verifier-specific questions
Yes. Use page scan to inspect visible media on the active tab and compare status badges.
You may see No credentials even when the original master was signed. Delivery preservation matters — see why CDN preservation matters.
