What is C2PA?
C2PA (Coalition for Content Provenance and Authenticity) is an open standard backed by Adobe, Microsoft, Google, OpenAI, camera makers and media companies. It attaches a cryptographically signed manifest to a file — branded as Content Credentials — that records which tool created or edited the image and what actions were taken, for example “created with a generative AI model”.
Inside a JPG the manifest lives in APP11 segments as JUMBF boxes; in PNG it is a caBX chunk; in WebP it is a dedicated RIFF chunk.
Manifests are often surprisingly large — 30 to 70 KB is common — so removing them also makes files lighter.
How Clean Image Metadata removes it
We locate every JUMBF/C2PA block, drop it and rebuild the file around the untouched image data. Because the manifest is signed, partial edits would simply break it; full removal leaves a valid, standard image. Run the result through the checker to confirm.
Important: removal is visible in other ways
C2PA is designed so that tampering can be noticed, and some providers keep a server-side record or a pixel watermark that can re-link an image to its credentials. Removing the manifest is useful for privacy and file size, but it is not a way to hide that content was AI-generated where disclosure is required.
Frequently asked questions
Does removing C2PA damage the image?
No. The manifest sits next to the image data, not inside it. Clean Image Metadata copies the compressed image unchanged.
Can C2PA be restored after removal?
Not from the cleaned file. Keep your original if you may need its Content Credentials later.
Which apps add C2PA?
Among others: ChatGPT/OpenAI image generation, Adobe Firefly and Photoshop (Content Credentials), Microsoft Designer/Bing Image Creator, some Google products, and cameras from Leica, Sony and Nikon with provenance features.
