Check a file without uploading it
Your browser works out the file’s SHA-256 and sends only that fingerprint to SMI’s public registry. The file stays on your device.
What each report inspects
Embedded metadata
Reads EXIF and XMP where the file type carries them, and notes whether IPTC data is present.
Content Credentials
Validates C2PA when present, and says so when it can’t. Missing credentials are not proof of fraud.
