C2PA Detector: Check Images for Content Credentials
C2PA Content Credentials are signed provenance manifests that can record how media was made and edited. This browser tool performs a quick private search for familiar C2PA, JUMBF and Content Credentials marker strings. It does not parse a manifest, validate its signature or return a definitive provenance verdict.
If credentials are present and you need a clean file, the detector routes you to the remover that strips them.
What C2PA / Content Credentials Are
A signed manifest in the file header naming the model and timestamping the generation.
C2PA (the Coalition for Content Provenance and Authenticity) defines a tamper-evident manifest — often branded "Content Credentials" — embedded in JPEG, PNG and other files. It can name the generating model, timestamp the creation, and chain edits together. For AI images it's the clearest machine-readable proof of origin, which is exactly why so many platforms scan for it on upload. This detector looks for the C2PA, JUMBF and Content Credentials markers in the file bytes and reports what it finds.
Where C2PA Comes From
AI generators, editing software, and increasingly the camera in your phone.
C2PA can appear on images from AI generators, editing software and supported cameras. A conforming parser and verifier can inspect a manifest and its signature; a marker-string scan like this one cannot establish that the manifest is valid or absent. C2PA is also separate from pixel-domain watermarks that may survive metadata stripping.
Detect, Then Remove the Credentials
One pass from finding the manifest to downloading a file without it.
When Content Credentials are found, the "Remove" button routes to the remover, which rewrites the file to drop the C2PA manifest and other provenance metadata while leaving the visible image untouched. If your image is from Gemini or ChatGPT, note that stripping C2PA alone won't remove SynthID — use the SynthID detector and remover for the pixel-level layer.
