C2PA Checker: Content Credentials Viewer

Upload an image or video and we will show its C2PA manifest if there is one: which app wrote it, whose certificate signed it, which actions it declares (created by AI, edited), plus XMP DigitalSourceType and EXIF Software.

Manifest and signer

Claim generator, organization and issuer from the X.509 certificate, signature algorithm, TSA timestamp, manifest history and ingredients.

Created or edited by AI

c2pa.created / c2pa.edited actions with digitalSourceType: trainedAlgorithmicMedia, compositeWithTrainedAlgorithmicMedia and other IPTC codes.

Full signature validation

File integrity and certificate trust are validated by the official service contentcredentials.org/verify.

Fatos principais

C2PA (Content Credentials) is a signed manifest inside a file: who made or changed it and with what, including AI. Upload a photo or video and we show the manifest, signer and actions. We do not validate the signature, and a missing manifest does not prove a file is genuine: metadata is often stripped on re-save.

Preço: Grátis
Cadastro: Não é necessário
Processamento: On our server: the file is uploaded to a temporary folder, its C2PA manifest, XMP and EXIF are read, and the file is deleted after the response
Entrada: Uma imagem (PNG, JPG, WebP, GIF, TIFF, AVIF, HEIC) ou um vídeo (MP4, MOV, M4V, WebM, MKV, AVI)
Limites: No sign-up; images up to 25 MB, videos up to 80 MB; 10 uploads per minute per IP. The signature is not cryptographically validated
Resultado: A report: the C2PA manifest (authoring app, signer, algorithm, time), actions and source type (AI-generated, camera capture), XMP DigitalSourceType, EXIF Software; a link to full validation

C2PA Checker and Content Credentials Viewer

C2PA (Content Credentials) is an open standard that lets cameras, editors and AI generators write a signed manifest into a file: what made it and what was done to it. The tool finds the manifest in JPEG, PNG, WebP, AVIF/HEIC and MP4/MOV, parses it and shows the signer from the certificate, the app, the actions and the source type (for example trainedAlgorithmicMedia, meaning generative AI), plus XMP and EXIF. The signature is not verified cryptographically — a link to the official verification service is provided for that.

FAQ

C2PA is an open standard for signed provenance metadata: what created a file, what edits were made and who signed it. Content Credentials is the user-facing name for this technology.

Upload the file: if the generator wrote a manifest or XMP DigitalSourceType, we show it. But missing labels prove nothing, because metadata is easy to strip and not every generator writes it.

Usually the metadata was removed by a screenshot, compression or a social upload. Some services and local models do not write C2PA at all.

No. We read and display what the manifest declares, but for file integrity and certificate trust use the official verification service; the report links to it.

Imagens PNG, JPG, WebP, GIF, TIFF, AVIF ou HEIC de até 25 MB e vídeos MP4, MOV, M4V, WebM, MKV ou AVI de até 80 MB. O arquivo é excluído após a análise.

PromoPilot vs. alternativas: comparação

Comparamos apenas o que está confirmado nas páginas de cada serviço. Onde não conseguimos confirmar um dado, a célula mostra "—".

Parâmetro	PromoPilot	c2pa-rs (SDK, c2patool)
Reads the C2PA manifest, XMP, EXIF	✓	✓ the SDK can parse manifests
Cryptographic signature validation	✗	✓ the SDK creates, signs and validates manifests
Video files	✓	—
Free, nothing to install	✓	✓ MIT / Apache-2.0; needs installing

Role a tabela para os lados

Onde somos mais fracos: we do not validate the signature or certificate trust, the file goes to our server and the report is limited to what is written in the metadata.

Quando escolher o PromoPilot: When you want to quickly read what the manifest declares and see XMP/EXIF without installing software. To check signature integrity and certificate trust, use the official service or c2patool.
