What are Content Credentials (C2PA), and how do you check them?
Content Credentials, built on the open C2PA standard, are a cryptographically signed record attached to an image that says who made it, with what tool, and how it was edited. Unlike plain EXIF, any change to that record breaks the signature, so it cannot be quietly altered. You can check them at contentcredentials.org, c2paviewer.com, or on ChronoVerify.
What they record
Think of Content Credentials as a nutrition label for a photo. A manifest travels with the image and can record the capturing device or software, the time and place, the edits applied, and whether AI tools were involved at any stage. Each step is signed, so the record is verifiable rather than just asserted.
Why they are stronger than EXIF
Plain EXIF metadata is useful, but anyone can edit or remove it with free tools, so it is a claim, not a guarantee. Content Credentials add cryptographic signing: if a single field in the recorded history is changed, the signature no longer validates and the tampering is detectable. That is the difference between "the file says this" and "this can be checked."
Who is adopting them
2026 is the year this moved from a niche idea toward something photographers, newsrooms, and platforms need to understand:
- Cameras and phones have begun signing photos at capture, including recent flagship devices.
- AI generators such as OpenAI's tools, Adobe Firefly, and Google's image models embed credentials that label output as AI-generated.
- Platforms and editors are adding support to preserve and display the credentials.
How to check them
Upload the image to a dedicated viewer like contentcredentials.org or c2paviewer.com, where the validation happens in your browser, or check it on ChronoVerify, which detects Content Credentials alongside EXIF, capture time, and a plain verdict. A valid credential confirms what the signer recorded about creation and edits. It does not, by itself, prove that the scene in the photo is true.
The honest limits
Most images you encounter today are still unsigned, and that is normal. The absence of Content Credentials is not evidence that an image is fake. Treat a missing credential as "no signed history available," and fall back to EXIF, capture-time consistency, and other corroboration.

What is the difference between C2PA and EXIF?
EXIF is plain metadata that anyone can edit or strip. Content Credentials, built on C2PA, are cryptographically signed, so any change to the recorded history breaks the signature and is detectable.
Does every photo have Content Credentials?
No. Most images in the wild are still unsigned. Adoption is growing fast, but the absence of credentials is not evidence that an image is fake.
How do I check an image's Content Credentials?
Upload the file to a viewer such as contentcredentials.org or c2paviewer.com, or check it on ChronoVerify, which detects Content Credentials alongside the rest of a photo's metadata.
Do AI image generators add Content Credentials?
Many do. Major generators including OpenAI's tools, Adobe Firefly, and Google's image models embed Content Credentials that label their output as AI-generated.
