What is C2PA?

C2PA (Coalition for Content Provenance and Authenticity) is a technical standard for embedding provenance metadata into media files. It records information about how content was created — which tool made it, what edits were applied, and when.

Tools like ChatGPT, Adobe Photoshop, Google Gemini, and Midjourney automatically embed C2PA metadata into the files they produce. This metadata is invisible to the human eye but can be read by software.

Social platforms including Instagram, LinkedIn, YouTube, and TikTok now read C2PA metadata and use it to add "Made with AI" labels to content. This can happen even when the content is a real photograph that was only slightly retouched with AI tools.

Use the checker above to see if your file contains C2PA metadata. If it does, you can remove it with our C2PA remover.

Found C2PA metadata? Remove it in seconds.

Strip content credentials from your videos and images. Lossless quality, no re-encoding. Stop "Made with AI" labels before you publish.
