Gemini image provenance
Gemini watermark checker: SynthID & C2PA
Check Gemini, Imagen, and Nano Banana images for C2PA Content Credentials, EXIF/XMP metadata, and generator tags, then continue to Google’s official SynthID verification for the embedded pixel signal.
- C2PA and image metadata
- Official SynthID handoff
- Nano Banana search coverage
Provider verification
Gemini Watermark Checker is coming soon
We are connecting and validating the provider-specific verification required for dependable results. This page will open when that check is ready.

Use the AI Watermark CheckerHow the Gemini watermark checker works
This page completes the file-level provenance pass and shows the exact metadata and C2PA evidence it found. Google’s SynthID check is presented as the next provider verification step because it examines a different signal inside the media.
Official SynthID check
Continue to Gemini’s supported SynthID verification for image, video, or audio signals controlled by Google.
Visible mark review
The report keeps visible logos as a separate pixel-review step alongside metadata and Content Credentials.
C2PA fields when returned
Issuer, generator, actions, validity, and trust are shown only when the validator returns them.
Checker or cleaner?
This page tells you which layers exist. The Gemini Cleaner removes supported visible marks. Check first, clean second.
Evidence you can use
Every report separates cryptographic credentials, declared metadata, and provider-controlled verification. You can see exactly what ran before deciding what the file proves.
- C2PA Content Credentials parsing and cryptographic validation for supported files.
- Declared EXIF, XMP, IPTC, container, and generator metadata evidence.
- A precise boundary and official path for provider-controlled verification when one exists.
Frequently asked questions
How do I check a Gemini SynthID watermark?
Run the C2PA and metadata pass here, then follow the official Google source to verify SynthID in Gemini for supported image, video, or audio. The two results examine different provenance layers.
Is SynthID the same as a visible Gemini logo?
No. SynthID is an embedded provider signal, while a visible logo is pixel content and C2PA is file metadata. A file can carry different combinations, so the report keeps all three layers separate.
What is the difference between this checker and the Gemini Cleaner tool?
The cleaner removes the supported visible Gemini marks from your images. This checker tells you first which layers exist: visible marks, metadata, and C2PA. Use the checker to understand, the cleaner to edit.
Does removing metadata remove SynthID?
No. SynthID survives metadata stripping because it lives in the pixels. Cleaning metadata changes the file's provenance records, not the embedded watermark.
