C2PA Content Credentials Checker

Drop an image to check whether it carries C2PA / Content Credentials metadata, the provenance standard used by DALL·E, Adobe Firefly, Photoshop and a growing list of cameras. The checker shows the signals found at the byte level, and is upfront about what it does not do.

What are C2PA Content Credentials?

C2PA (Coalition for Content Provenance and Authenticity) is an open standard for recording where an image comes from. Participating tools embed a manifest (stored as a JUMBF block inside the file) that declares the capture device or generator, the editing steps, and whether generative AI was used. Adobe markets it to end users as Content Credentials.

What does this C2PA checker show?

ExifClean scans the file at the byte level for C2PA containers (JUMBF / caBX boxes) and C2PA-related XMP tags, alongside the rest of the metadata: IPTC digitalSourceType, generation parameters and software tags. If credentials are present you'll see exactly which signals were found and what the surrounding metadata declares about the image's origin.

Does it verify the C2PA signature?

This is a presence check, not a cryptographic verification: ExifClean does not validate the manifest's signature chain. An absent manifest also proves nothing: metadata is routinely stripped by social platforms and screenshots. For signature validation, use an official C2PA verifier; to see everything else a file contains, open the EXIF viewer or check for broader AI fingerprints with the AI image checker.

Frequently asked questions

What are Content Credentials?

Content Credentials are the consumer-facing name of C2PA, an open provenance standard. Tools that support it embed a signed manifest in the file describing how the image was created and edited, including whether generative AI was involved.

Which tools add C2PA metadata?

A growing list: OpenAI's DALL·E images, Adobe Photoshop and Firefly, some Leica cameras, and other editors and generators joining the C2PA coalition. Many images on the web still carry none at all.

Does this checker verify the C2PA signature?

No. It detects whether C2PA / Content Credentials data is present and shows what it declares. It does not cryptographically validate the signature chain; for that, use an official verifier such as the Content Credentials Verify site.

Can C2PA data be removed?

Yes. C2PA lives in the metadata layer, so stripping metadata removes it, which is exactly why provenance can never be assumed just because it's absent. You can remove it from your own images with the remove EXIF tool.
