3 Clean or rule out tags

Upload a photo to see whether file metadata still carries AI provenance - or whether a clean scan suggests pixel watermarks / platform classifiers instead.

Read-only, browser-only. This is not a SynthID detector or invisible-watermark remover.

Metadata diagnosis vs watermark removal

Searchers often mix three different problems: embedded C2PA/XMP (file tags), invisible pixel watermarks (SynthID-style), and platform visual classifiers (no tag in the file). This page only diagnoses the first - what your browser can read locally.

Use it when you already ran a remover but Instagram, TikTok, or Facebook still show AI Info: “Is something still in the file, or is the label coming from elsewhere?”

How to read the results

AI tags found - Open the AI-only metadata remover to strip provenance while keeping camera EXIF on JPEG
No AI tags - Metadata is unlikely the trigger; read the disclaimer on pixel watermarks and re-upload rules (screenshots, forwards)
Re-check after every export - WhatsApp, cloud previews, and editor re-saves can re-embed or strip data
Still labeled with a clean file? - We cannot scan SynthID; consider a fresh export or platform appeal paths outside this tool

What this checker does not do

Does not detect or remove SynthID / invisible steganography
Does not run cloud “is this AI art?” pixel classifiers
Does not guarantee future platform policy changes
Does not replace the C2PA checker when you need signature verification detail

Checker → AI-only clean → upload

Typical fix path when metadata is the culprit: scan here, clean with AI-only mode if C2PA or XMP AI entries appear, confirm with the metadata checker , then upload the downloaded master - not a chat forward or platform re-compress.

For generator PNGs with no camera EXIF, the full AI metadata remover is often simpler.

PDF attachments

Deck or portfolio PDFs carry separate Document Info - images inside are not cleaned when you strip the PDF wrapper.

FAQ

Is this an AI watermark remover?

No. It is a read-only metadata scanner. Removing tags requires the linked remover tools. Invisible watermarks are outside scope.

I cleaned metadata but Instagram still shows AI Info - why?

Either residual tags in a different file (story vs feed), re-compression from a messenger, pixel/classifier signals, or platform-side history. Use this checker on the exact bytes you upload.

AI watermark checker vs AI image checker?

Both read file metadata locally. This page emphasizes post-clean diagnosis and non-metadata causes; the AI image checker targets pre-upload scans.

Does a clean scan guarantee no label?

No. It only rules out readable AI provenance in the file you tested.
