How do I remove C2PA metadata?

Question

Accepted Answer

C2PA Content Credentials are stored as a JUMBF binary block embedded inside the file (PNG, JPEG or MP4), so cropping or re-saving won’t remove them. The direct way is ExifTool with -all=, which wipes every metadata group including the JUMBF container. The cleaner way is a tool that strips the container and then injects authentic phone-capture metadata in its place, so the file doesn’t look suspiciously empty. Afterward, verify at contentcredentials.org/verify — if it reports “no Content Credentials found,” the strip worked. Calabi Sanitizer does the strip, the identity injection and the verification in one pass.
