Look for a supported C2PA marker

C2PA Content Credentials marker check

Choose an image to check for a supported Content Credentials marker. This quick check runs on your device; it does not read claims, verify signatures, or determine who made the image.

IMAGE CHECK // READY

Looks for a supported C2PA marker in the image structure. This local check does not read claims, validate signatures, or identify who made the file. Supports JPEG, PNG, and WebP up to 25 MB.

How a signed record works

What a full Content Credentials check would read

Finding a marker means a source record may be present. A full check would also examine these parts:

01Container

Where the record is stored

A place in the file where the signed record can be stored. This quick check looks for that place.

02Origin

How the image was made

The record may describe a camera, editor or AI tool used to make the image. That information still needs to be checked.

03Edits

Recorded edits

A record may list edits such as cropping or AI-assisted changes. It does not guarantee that every earlier edit was recorded.

04Security

Signature and file link

A full check verifies the signature and its link to this file. This quick tool only looks for a possible record.

What different source records can tell you

These are examples of what a signed record might say. This quick tool does not read or verify the information inside it.

CameraExample record

Captured by a camera

Some cameras can sign a record at capture. A full check must verify which device signed it and whether that signer is trusted.

Possible claimCamera capture
Still needs checkingSignature and signer
What it cannot proveThat the scene is true
Generative AIExample record

Made with an AI tool

Some AI tools add a signed record about how they created an image. Not every AI image has such a record.

Possible claimAI generation or edit
Still needs checkingSignature and exact claim
What absence meansNothing by itself
Social MediaShared copy

Downloaded or shared image

Sharing or exporting may remove a signed record. Its absence does not say whether the image came from a camera or AI.

Quick-check resultNo marker found
What to ask forEarlier file if available
What absence meansNo conclusion about origin

Why a copy may lose its signed record

A signed source record belongs to a particular file. Cropping, compressing or taking a screenshot can change that file or remove the record. Finding a marker alone does not confirm that the record still matches the image.

C2PA also defines ways to help find records for some changed copies. Whether such a method works depends on the file and service, and it is not part of this quick check. See the C2PA specification for technical details.

Frequently Asked Questions

What are Content Credentials?

They are signed records that may describe how an image was made or edited. This page's quick check looks for a possible record in the file; it does not validate the signature or confirm the claims.

Does the absence of a C2PA marker mean an image is fake or AI-generated?

No. Many images have no Content Credentials. Editing, exporting, taking a screenshot or sharing an image can remove them. Their absence does not tell you whether AI was used.

Does finding a record prove the image is authentic?

No. A full validator must check the signature, the link to the file and whether the signer is trusted. Even a valid record only supports the claims it contains; it does not prove the scene is true.

Can a signed record say whether AI was used?

It may include a claim about camera capture, editing or AI generation. Read the exact claim and check who signed it. The marker check on this page cannot read or verify those claims.
