What Are C2PA Content Credentials?

C2PA (Coalition for Content Provenance and Authenticity) is an open technical standard backed by Adobe, Microsoft, Google, Intel, and Leica. It binds cryptographic assertions to image containers to track asset lineage and author identity:

Author & Tool SignaturesX.509 cryptographic certificates issued to software tools or creators certifying origin.
Editing Lineage HistoryA tree of historical edits including cropping, color grading, adjustments, and inpainting.
AI Generation AssertionsDeclarations specifying whether generative models (e.g. Adobe Firefly or DALL-E) synthesized pixels.
ISO JUMBF ContainersStandardized binary boxes (ISO/IEC 19566-5) storing compressed JSON-LD claims and manifests.

Container-Level Lossless Stripping

Our parser locates the binary JUMBF manifest blocks and removes them from the file container without re-encoding the compressed image stream. Your pixel data remains 100% untouched.

Supported Formats

  • JPEG (.jpg): Strips APP11 marker segments holding JUMBF payload boxes.
  • PNG (.png): Purges caDX, c2pa, and jumb ancillary chunks.
  • WebP (.webp): Removes c2pa and jumb RIFF chunks.

Manifests vs. Invisible Pixel Watermarks

Removing C2PA removes the declarative container manifest. It does not alter invisible steganographic pixel watermarks (such as Google SynthID or DeepMind imperceptible frequency marks embedded into pixel values). Our two-pass verification scanner rescans the file container to verify that 0 C2PA manifests remain before reporting success.

How to Remove C2PA Credentials in 4 Steps

  1. Select your file: Drag and drop any image suspected of containing Content Credentials.
  2. Scan C2PA blocks: Click "Inspect Metadata" to detect JUMBF and C2PA markers.
  3. Strip manifests: Choose "Remove C2PA Content Credentials".
  4. Verify and download: Review the verification check confirming 0 manifests remain, then download.
