What does C2PA stand for?
C2PA stands for the Coalition for Content Provenance and Authenticity. It's a joint standard developed by Adobe, Microsoft, Intel, BBC, Sony, OpenAI, Google, and Meta to answer one simple question: "Where did this image come from?"
When you see the term "Content Credentials" — that's C2PA in consumer-friendly branding. Same thing.
How C2PA actually works (the 30-second version)
Every time an AI tool generates or edits an image, it can attach a small cryptographically-signed block of data inside the file. This block contains:
- Which tool made it (e.g. "OpenAI DALL·E 3", "Adobe Firefly", "Google Imagen 3")
- When it was created
- The prompt (sometimes)
- Edit history — every crop, filter, or AI-modification is appended
- A digital signature proving nobody tampered with the record
Anyone can drag the image onto contentcredentials.org/verify and read the whole history in seconds.
Which AI tools embed C2PA by default?

Why should you care about C2PA?
1. Platforms use it to label your posts as "AI"
Instagram, Facebook, Threads, LinkedIn, YouTube, and TikTok all read C2PA and automatically slap "Made with AI" badges on your posts. This can crush organic reach.
2. Advertisers reject C2PA-tagged creatives
Many ad networks (especially Meta Ads and Google Ads) demote or reject ads whose creative assets carry AI provenance data.
3. Stock sites and clients screen for it
Shutterstock, Getty, and most agencies now inspect C2PA before accepting submissions. AI-tagged files get bounced instantly.
4. Your prompt might be inside the file
Some tools embed the raw prompt in C2PA data. If you share the image publicly, anyone can read exactly what you typed.
How to check if an image has C2PA metadata
Option A — Official verifier
Drag your image onto contentcredentials.org/verify. Free, instant, works in any browser.
Option B — okie.fun AI Detector
Our AI Detector reads C2PA + XMP + EXIF + IPTC in one shot, 100% locally in your browser. Nothing is uploaded.
Option C — Look for the "CR" pin icon
On supported platforms (LinkedIn, Instagram), a small "CR" icon appears in the corner of AI images.
How to remove C2PA metadata
C2PA is stored as an embedded manifest inside the file (JPEG APP11 marker, PNG chunk, etc.). Standard "screenshot" or "re-save" tricks do not always work — modern tools can carry the signature through some conversions.
The reliable way: use a tool that specifically strips the C2PA manifest along with all other metadata.
okie.fun runs 100% in your browser. Your image never leaves your device.
Is removing C2PA legal?
Yes — in almost every jurisdiction. C2PA is a voluntary industry standard, not a law. You own your files and can remove any metadata you like, just as you can strip EXIF GPS data before posting a photo. However, misrepresenting AI content as human-made in regulated contexts (news, elections, ads in the EU under the AI Act) may carry legal consequences. Use responsibly.
FAQ
TL;DR
C2PA is the invisible passport AI tools stamp on every image. It tells platforms, advertisers, and stock sites that your content is AI-made — and that label often costs you reach, revenue, or approvals. Check your files with a verifier, and strip the metadata when you don't want it tagged.
