Quick answer
C2PA lets images and PDFs carry cryptographically signed provenance metadata. ChatGPT, Adobe Firefly, Microsoft Designer, Google Imagen, and others sign it.
Tools
- C2PA Stripper removes C2PA
- AI Image Inspector reads and displays it
- Strip Image Metadata removes everything (including C2PA)
When to strip
- You edited the image and the original provenance no longer fits
- You don’t want viewers to see its AI origin
- The prompt contained sensitive content
When to keep
- Publishing / marketing / editorial scenarios where provenance proof is useful
Note
C2PA is metadata; it doesn’t affect pixels. Stripping doesn’t degrade image quality.
