Two ways to verify media
Local files, page scans and detailed reports for C2PA Content Credentials.
Local file verification
Drop a JPEG, PNG, PDF, MP4, MOV or WebM file into the extension to inspect C2PA manifests, signatures, actions and certificate-chain information.
Page scanning
Run Analyze this page to inspect supported visible media on the current tab and display C2PA status badges.
Detailed reports
Open a report to compare manifest details, declared actions, signer information and JSON export data.
What happens during a check
How ProvSeal reads media, parses evidence and evaluates trust status.
The extension reads the selected file or visible page media in the browser context.
If C2PA data is present, the extension extracts manifest, claim and assertion information.
The report explains whether the media still matches the signed provenance evidence.
The certificate chain is used to determine whether the signature is Trusted, Signed but untrusted, Invalid or No credentials.
Interpret the result carefully
Status labels explain available evidence — they are not truth verdicts.
Valid Content Credentials with a recognized certificate chain.
The signature can be valid while public trust is not recognized.
C2PA data exists, but signature or integrity validation failed.
No C2PA evidence was detected. This does not mean the content is fake.
