A private inspection workflow
Open the metadata viewer and choose a JPEG, PNG or WebP file. The file bytes are passed to browser code and a Web Worker; the image itself is not posted to an AnalyzeImage upload endpoint.
Key points
- Verify that the extension matches the detected signature
- Check whether precise location was found
- Review dimensions, megapixels and animation
- Inspect camera, capture, rights and software groups
- Calculate SHA-256 only if you need a comparison fingerprint

What a browser can and cannot tell you
A browser can parse metadata and validate file structure, but it cannot guarantee that the values are truthful. Export software may remove fields, social platforms may rewrite files, and someone can edit metadata deliberately.
What this does not prove
A metadata result describes the fields and structures that the supported parser could read. It does not, by itself, prove authenticity, intent, authorship or the truth of the visible scene.
