What you'll see

Content Credentials

Whether the file carries a C2PA Content Credential, and whether its manifest is bound to this exact file.

Provenance

Recorded actions and ingredient references straight from the manifest — never inferred from file names or heuristics.

Signature

Cryptographic verification state plus signer and issuer information when the credential provides them.

How it works

  1. 1

    Drop a file

    Choose an image or video you want to inspect.

  2. 2

    Inspect locally

    The C2PA engine runs in your browser via WebAssembly — nothing is uploaded.

  3. 3

    Read the evidence

    See the verification state, provenance timeline, ingredients, and raw manifest data.

What C2PA can and cannot tell you

A credential can show

  • A signed provenance record bound to the file
  • Declared actions such as edits or creations
  • Declared use of generative AI, when stated
  • Ingredients the producer chose to record

It cannot prove

  • That every claim in the manifest is true
  • That unrecorded edits never happened
  • That a file without credentials is AI-generated
  • The overall authenticity of content

Frequently asked questions

What is C2PA?

C2PA (Coalition for Content Provenance and Authenticity) defines an open technical standard for attaching cryptographically signed provenance data to media files. See our guide to C2PA.

What are Content Credentials?

Content Credentials are the user-facing expression of C2PA provenance data: recorded actions, ingredients, and signer information embedded in a file.

Does C2PA prove that a file is authentic?

No. A verified signature proves the manifest is intact and bound to the file. It does not prove every recorded claim is true, and it cannot detect unrecorded edits.

What does it mean when no C2PA data is found?

It only means no C2PA provenance record was detected — many genuine files simply have none. It does not mean the file is fake, edited, or AI-generated.

Does C2PA Lab upload my files?

No. Inspection runs entirely in your browser using WebAssembly. Files never leave your device, and no file data is sent to any server.

Which file types are supported?

JPEG, PNG, WebP, AVIF images and MP4/MOV video files up to 200 MB are supported in modern browsers.
