Your choice travels with this copy of the photo, in ways compatible AI systems can potentially recognize.
What does this mean?
Your No AI Use choice is added in machine-readable forms. The invisible watermark carries a reference that can help retrieve the signed declaration if metadata is removed. Compatible systems can read your choice; it does not physically prevent copying, editing, or AI use.
Share from your device
Save the verified photo file, then use Share in Photos or Files to send it through your usual apps.
If this in-app browser does not save the file, open the original file above and use its save options, or open this page in Safari or Chrome and choose your photo again.
Save the photo file itself. Copying the image or taking a screenshot can remove the attached declaration.

The service signs and registers the declaration. The exported C2PA credential and separate registry proof are checked locally. Development credentials are untrusted; no trusted timestamp is attached.
Getting ready…
Check a photo
Check a shared photo or screenshot for an AI-use declaration. Recovery depends on the invisible reference remaining readable.
Declaration check
- Declaration
- AI-use choice
- Signature
- Photo connection
Photos are checked on your device. If a watermark reference is recovered, only that reference is sent to look up its saved declaration.
Finding a declaration does not show that a platform honored it, or establish ownership.
About this result
Photo reference:
Registered:
The reference links to this record. It does not independently establish image correspondence or ownership. A screenshot or camera photo may not retain a recoverable reference.
Same-format photo copies · Maximum output edge 2048px · Re-encoding may change color and removes original metadata. HDR is rendered to 8-bit color. Larger photos are resized. Animations, multipage images and RAW files are not supported. Keep your original.
Photos are processed locally; a restricted cross-origin frame sends only the reference, format, final photo binding digest, byte length and signing ticket to the service. Your fingerprint stays local. Signing and retrieval require connectivity. This signal does not enforce AI permissions.
Technical test report
Contains media reference IDs, dimensions and timings. No photo or original filename is included.
