About Cert.Photos
Last updated: October 6, 2026
What we do
Cert.Photos proves that a photograph is real.
When someone takes a photograph using our mobile app, we create a cryptographic record of that capture — a fingerprint of the image, the time it was taken, and, if the photographer allows it, where. That record is signed and attached to the photograph using C2PA content credentials, the open industry standard for content provenance. Anyone who later receives the photograph can check it against our public verification page and see that it is unaltered since it was certified.
The problem we exist for is simple to state: generated and manipulated images are now indistinguishable from photographs by eye. Proving that something is fake does not scale. Proving that something is *real* does.
Who uses it
- Photographers and journalists who need their work to be provably their own, and provably unedited.
- Anyone documenting something that matters — an accident, a condition, a claim — where being believed later is the point.
How the service works
- Capture. The photograph is taken inside our app, using our camera. Photographs cannot be imported from a device's photo library; this is deliberate, and it is what lets us make a claim about the moment of capture at all.
- Certify. Our servers embed an invisible watermark, then sign a C2PA manifest for the image using certificates issued by a publicly trusted certificate authority, with a trusted timestamp.
- Verify. Every certified photograph gets a public verification page at
https://cert.photos/v/<id>. Anyone with the link can check it. No account is needed to verify.
What we sell
Every photograph, on every plan, is certified the same way: a signed C2PA manifest with a trusted timestamp, an invisible watermark embedded in the pixels, and a fingerprint anchored to a public ledger. Plans differ in how many photos you can certify each year and in account features.
- Free tier — full certification and a public verification page for every photograph, for up to 100 photos a year. No payment method required.
- Pro tier — up to 10,000 photos a year and a verified-user indicator. Purchased on our website, not through the app stores. See Refunds and Cancellation.
- Enterprise — account management for institutional users. Offered under a separate agreement; not generally available to consumers.
We do not sell personal information. See our Privacy Policy.
How we keep it safe
Cert.Photos has no public feed, no comments, no direct messages and no follows. A shared photograph is a dead-end verification link. We have zero tolerance for child sexual abuse material and report it to NCMEC — see our Child Safety page — and anyone can report content without an account.
