OpenAI attaches C2PA-style provenance to many downloads.
Instagram and Facebook use those manifests in automated disclosure — remove them here before posting when the label is metadata-driven.
Why DALL·E files often show Meta's AI Info label
Meta has publicly described C2PA as an important signal for AI disclosure on photos. OpenAI's image pipeline writes content credentials into many downloads so downstream apps can reason about provenance. That supports transparency workflows — and it is what you typically strip when your goal is an upload without metadata-driven disclosure, as long as you still meet any legal duties where you operate.
What you should remove for OpenAI exports
- C2PA / JUMBF manifests and embedded assertion stores
- Auxiliary XMP generation or software fields if present
- Obvious default filenames after you have cleaned bytes
If you composite a DALL·E plate into Photoshop, you may inherit Adobe C2PA as well — flatten and process the final export once.
DALL·E vs Midjourney vs Stable Diffusion
Each toolchain fingerprints differently: OpenAI → C2PA-first, Midjourney → XMP-heavy, ComfyUI / SD → PNG text chunks. Read the comparison article: DALL·E vs Midjourney vs Stable Diffusion metadata.
Workflow
- Download your ChatGPT / DALL·E image.
- Upload here with C2PA removal enabled.
- Download the cleaned PNG or JPEG.
- Rename if the default name advertises the generator.
- Optional: confirm empty readout in the checker.
- Post to Instagram, Facebook, Pinterest, or TikTok.
FAQ
API responses behave the same as ChatGPT UI downloads?
Treat every binary response as untrusted: some code paths strip metadata, others preserve it. Always verify the bytes you ship.
Does Pinterest read C2PA the same way?
Pinterest publicly discusses layered GenAI detection; C2PA is still a high-signal block on many assets. Clearing C2PA is the correct first step before pinning OpenAI exports — see the Pinterest guide.
