# C2PA Lab
Tool Description : A browser-based tool for inspecting media provenance, without uploading files, by reading C2PA Content Credentials locally in the browser.
| **C2PA Lab** | **Quick Overview** |
| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| URL | |
| What it does | Inspects C2PA manifests in images and videos and shows verification state, provenance timeline, ingredients, and signer/issuer details from the manifest. |
| How to use it | Open the site, drop or select a JPEG, PNG, WebP, AVIF, MP4, or MOV file up to 200 MB, then review the credential evidence and manifest details. |
| Cost | Free with no ads or signup. |
| Account required | No. |
| Cookies | Google Analytics. |

| Use in Reporting | Useful for verifying and documenting digital provenance, Content Credentials, recorded edits, ingredients, and signing information in images and video. |
### What does CP2A Lab do?
C2PA Lab is a free web tool for inspecting C2PA Content Credentials and digital provenance in images and videos. It reads the file locally with WebAssembly and reports what the manifest records: verification state, provenance timeline, ingredient references, recorded actions, and signer/issuer details.
A Manifest Viewer exposes the manifest store, active manifest, claims, assertions, and JSON; a Metadata Inspector presents selected fields in a structured table. A Proof Card can be rendered locally as a 1200x630 PNG summary.
**The lowdown:** It provides a way to examine what a C2PA-compatible system has cryptographically recorded about a piece of media, rather than relying solely on conventional metadata or visual inspection.
### How to Use:
**1. Open then drop or choose a supported media file up to 200 MB.**
**2. Review the evidence view for verification state and manifest-recorded provenance.**
**3. For technical review, open Manifest Viewer / Metadata Inspector.**
**4. Use the public example files if testing the workflow:**

### Cookies:
C2PA Lab uses Google Analytics cookies, including \_ga and \_ga\_70L9YB69CY, to distinguish visitors and measure website/session activity.
### Use in Reporting
C2PA Lab can be used to:
* Verify whether an image or video contains C2PA Content Credentials.
* Examine cryptographically signed provenance associated with digital media.
* Identify recorded creation, editing or production actions.
* Identify source or ingredient files referenced by a provenance record.
* Examine signer, issuer, certificate and signature information where available.
* Compare provenance information with claims made about how or where media was produced.
* Document validation failures, hash mismatches or other provenance issues.
* Establish whether provenance evidence remains attached to a particular copy of a file.
* Support fact-checking and verification of photographs, videos and potentially synthetic media.
* Preserve technical provenance findings as part of an investigative evidence trail
**Note:** A valid credential supports statements about recorded provenance and cryptographic binding, but absence of C2PA is not evidence that content is AI-generated.
| **Capabilities** | **Limitations** |
| ------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------- |
| Local browser inspection of C2PA Content Credentials. | Requires media to contain a C2PA manifest to return credential evidence. |
| Supports JPEG, PNG, WebP, AVIF, MP4, and MOV up to 200 MB. | Cannot prove that all real-world claims in a manifest are true. |
| Shows verification state, provenance timeline, recorded actions, ingredient references, and signer/issuer details. | It’s not an AI detector and cannot identify manipulated content without recorded provenance. |
| Manifest Viewer exposes manifest store, claims, assertions, and JSON. | Absence of C2PA data does not mean content is AI-generated. |
| Manifest Viewer exposes manifest store, claims, assertions, and JSON. | File inspection workflow does not replace full forensic analysis or chain-of-custody review. |
| Proof Card export rendered locally as a 1200x630 PNG. |

### Summary
C2PA Lab is a strong option for the provenance/content-credential step of media verification when a file may contain C2PA data. Its’ main advantage is local inspection and manifest-level transparency however only recorded evidence can be shown, with no inference about authenticity or AI generation.
### Ownership
C2PA Lab; the site identifies itself as an independent tool and not affiliated with C2PA.
The site's [privacy policy](https://c2palab.com/privacy/) provides a contact address at , while a current independent corporate ownership structure is not clearly identified on the site.
### Ethical Considerations
* Treat C2PA evidence as provenance evidence, not proof of truth or authenticity.
* Do not infer AI generation from absent credentials.
* Preserve source files and avoid basing serious published claims only on one verification signal.
* Be careful with sensitive media and personal data embedded in files; C2PA Lab keeps selected files local during inspection but cannot control downstream handling after download.
