Content Credentials checker
Drop an image to see whether it carries C2PA Content Credentials — who signed it, what tools made it, and whether AI was involved. Free, unlimited, and nothing is uploaded.
How do you check an image's Content Credentials?
Content Credentials (the C2PA standard) are a signed record inside an image describing its origin — the capturing device or app, any AI involvement, and the edit history. This free C2PA viewer reads that record in your browser using the official verification library, shows who signed it and whether the signature is valid, and can strip credentials from a copy if you need to publish without them. Nothing is uploaded.
Re-saves the image without any embedded metadata. Quality is preserved.
Frequently asked questions
What are Content Credentials (C2PA)?
Content Credentials are a tamper-evident record attached to an image showing where it came from — which camera or app made it, whether AI was involved, and what edits were applied. They follow the C2PA standard backed by Adobe, Google, Microsoft, Samsung, OpenAI and others.
Does this prove an image is AI-generated?
Only if the creator attached credentials. Many AI tools now sign their output, so credentials saying "generated with AI" are strong evidence. But the absence of credentials proves nothing — they are frequently stripped by social platforms and re-saving. Treat "no credentials" as "unknown", not "authentic".
Are my images uploaded anywhere?
No. Verification runs entirely in your browser using the official C2PA library compiled to WebAssembly. Your images never touch a server — useful when you are checking sensitive or unpublished material.
Why would I remove Content Credentials?
Credentials can contain your name, software, device and edit history. If you are publishing anonymously or sharing a photo where that trail is private, stripping it is reasonable. Note the EU AI Act requires AI-generated content to remain marked in many commercial contexts — do not strip credentials to disguise AI content.
Which file types work?
JPEG, PNG, WebP, AVIF, TIFF and common video and audio formats can carry credentials. Drop any of them to inspect; stripping is available for JPEG and PNG images.
