Verification
Upload an image to inspect its cryptographic Content Credentials and provenance manifest.
The scanner uses the official C2PA WebAssembly SDK to parse signed JUMBF manifests entirely in your browser.
What it is, how it works, why platforms read it.
What is C2PA?
An open standard from the Coalition for Content Provenance and Authenticity that binds a verifiable history (the provenance) to a digital file. Unlike EXIF — easy to edit — C2PA uses cryptographic signatures embedded as JUMBF blocks.
How it works
When a C2PA-enabled camera or AI tool produces an image, it generates a signed Assertion Manifest with claims about the creator, edits, and timestamps. The block is hashed and signed with public-key crypto. If a single pixel changes after the fact, validation breaks.
Why platforms read it
Meta, Pinterest, and others parse C2PA on upload to auto-tag AI content or limit distribution. The cleaner rebuilds the image from raw pixels, so the signed chain isn't carried into the export.
