Checking and cleaning AI image metadata: a guide index

Plain-language guides on what is actually inside AI-generated and AI-edited images (C2PA Content Credentials, EXIF/GPS, XMP, PNG text chunks), how to check a file yourself, and what removing it does and doesn't do.

Understand the marks

• SynthID and Content Credentials are two different marks
• Gemini and Imagen images: what's in the downloaded file
• Does a screenshot remove C2PA data from a ChatGPT image?
• What metadata is inside a Midjourney download?
• SynthID is not a row in the inspect report

Check a file

• Check for C2PA with a short Python script
• Check with c2patool (two commands)
• Stable Diffusion and ComfyUI PNGs carry your prompt

Platforms and editors

• What triggers Instagram's "AI info" label
• The LinkedIn "CR" icon on photos
• Photoshop Generative Fill and Content Credentials
• Photographers: GPS, serials and AI edit history before delivery
• Five fields in LinkedIn's CR panel, and the AI-only pass

Written by the maker of Remove AI Meta, a browser tool that inspects and strips metadata locally. Removing metadata does not remove invisible watermarks such as SynthID and does not change any duty to disclose AI use.
