C2PA Evidence and Signed Samples

Download synthetic JPEG, PNG, TIFF, and WebP samples with embedded C2PA manifests created using the Proof of Publish July 8, 2026 conformance-submission profile: C2PA specification 2.2, claim generator Proof of Publish 1.0.0, ES256 signing, and RFC 3161 timestamp evidence. Upload an unchanged sample to Content Credentials Verify to inspect its content binding, assertions, and validation findings.

The samples use a historical conformance-test signing certificate, so a verifier may report that test signer as untrusted. Current production trust is separate: inspect the live C2PA Conformance Explorer for the Proof of Publish LLC product record, the applicable signer trust anchor, and the TSA trust record.

Product conformance does not certify customer identity, content truth, authorship, origin, first publication, ownership, or legal compliance. Publisher declarations are customer supplied unless a separate identity credential verifies them. Article sidecars are not part of the conforming-product scope or this public embedded-image sample set.
