Legal note: Under the EU AI Act (Article 50, in force since August 2, 2026), AI-generated content must be labelled as AI-generated where required. Removing technical watermark signals (C2PA, metadata, signatures) does not remove this legal obligation. Read our compliance overview →

Purification uses resizing and re-encoding to weaken latent signals. It does not guarantee SynthID removal.
Re-encoding weakens latent signals — no guarantee of SynthID removal. The encoder (~30 MB) is downloaded on first use.
Video too large for in-browser re-encoding (max 150 MB).

How to use the tool
- Add content. Drop an image or video, or paste text. Analysis starts immediately in your browser.
- Read the report. Inspect the C2PA manifest, metadata, and generator signatures.
- Clean the file. Confirm ownership, then download the cleaned copy or use purification to weaken latent signals.
What the tool does
C2PA detection
Decode Content Credentials from Adobe, OpenAI, Google, and others, including actions and producer data.
Metadata
Search EXIF, XMP, and container chunks for AI generator signatures.
Surgical cleanup
Remove provenance blocks without reducing image quality.
Purification
Re-encode images and videos to weaken latent signals, with no guarantee of SynthID removal.
Text
Review statistical indicators of AI writing for informational use.
How detection works
2. Signature matching
Check 13 signature families across C2PA manifests, EXIF, XMP, and text chunks.
3. Verdict
Combine the available evidence into a clear detection report without uploading the file.
Known limitations
- Latent watermarks such as SynthID are not directly detectable. The tool reports statistical text indicators and offers media purification instead.
- Visible watermarks such as logos or text overlays are out of scope.
- Video cleanup is surgical (C2PA removal) and video purification re-encodes the file in your browser (WebAssembly encoder, max 150 MB, first use downloads ~30 MB). Re-encoding weakens latent signals without guaranteeing removal.
Detection engine validated against official C2PA test files (contentauth/c2pa-js, Apache-2.0). Validated August 2026.
Frequently asked questions
Is it free?
Yes, 100% free, no account, no storage. Everything runs locally in your browser.
Do my files leave my device?
No. Files are processed locally; nothing is uploaded.
Is it legal to remove an AI watermark?
For content you own or have the rights to. You confirm ownership before downloading.
Which formats are supported?
JPG, PNG, WebP, MP4, MOV, AVIF and HEIC (full cleanup).
Can it remove visible watermarks (logos, text)?
No. It removes AI provenance signals such as C2PA, EXIF, XMP, and generator signatures.
Can it detect SynthID?
Latent SynthID is not directly detectable. The tool detects C2PA, metadata and generator signatures, and offers purification to weaken latent signals.
