AI Image Watermark Checker
Upload a JPEG, PNG, or WebP image to inspect supported watermark and provenance signals.
What this checker can verify
- C2PA Content Credentials and validation state.
- EXIF, XMP, PNG text, and recognizable generator metadata.
- Supported first-party provider signals when configured.
What it cannot verify
- A universal AI origin verdict.
- Whether missing provenance proves human authorship.
How to interpret the result
The strongest result is a provider-verified or cryptographically verified provenance signal. Metadata clues remain clearly labelled as supporting evidence.
No supported signal detected does not prove a file was created by a human. Metadata and credentials can be removed by screenshots, exports, editing, compression, or unsupported services.
