Does my file stay on my device while using the tools?
Yes. The default path processes supported images locally in the browser. An API upload requires separate, explicit consent.
Label AI Images with Complete Transparency.
Create visible disclosures, text overlays, and official EU icons for your images directly in your browser. Processed locally with zero data upload.
- No registration
- No upload
- Local processing
Four Steps to Transparent Labeling
From local image import to verified export. No registration required, zero cloud upload, complete privacy.
-
1. Open image locally
Select a JPEG, PNG or WebP image. Your file remains entirely within your browser.
-
2. Choose disclosure style
Use an official EU icon or customize a text overlay with your brand logo.
-
3. Set position & safe area
Position the overlay in a safe area and verify contrast against light and dark image regions.
-
4. Verify local export
Export at full original resolution. The generator automatically re-inspects the exported file locally.
Design and export a disclosure
The editor processes JPEG, PNG and WebP images directly in your browser. Choose a custom text disclosure or an official EU icon. Export preserves the full original resolution.
Free AI Transparency Tools
The disclosure generator runs directly on this page. Five more specialized local tools are available in the ContentSignal tool hub.
Disclosure Generator
Add visible disclosures and official EU icons locally.
Metadata Inspector
Inspect EXIF, IPTC and XMP metadata fields with zero file upload.
C2PA Checker
Verify C2PA Content Credentials, manifest chains, and signatures locally.
Privacy Metadata Cleaner
Strip sensitive GPS and camera metadata locally via clean re-encoding.
Verification Report
Record metadata and provenance state as a versioned JSON verification snapshot.
Video Inspector
Inspect MP4 and WebM video containers, codecs, and tracks locally.
Visible Notices & Machine-Readable Provenance
AI media transparency relies on two distinct layers: A visible overlay informs human viewers directly within the image. Machine-readable signals such as C2PA Content Credentials or XMP metadata store origin data securely in the file header. A robust workflow validates both layers post-export.
Recommended Disclosures
- “AI generated” for fully synthetic media
- “AI edited” for key elements modified post-creation
- “AI assisted” for human-led creation aided by AI tools
Disclosure Generator Questions
Answers about browser rendering, official EU icons, and output resolution retention.
Do I have to use an EU icon in the Disclosure Generator?
No. The EU icons are optional templates and already contain the visible label. In the generator, choose either an official EU icon or a text disclosure. You can still use your own logo together with custom text.
Which image formats does the disclosure generator support?
The generator processes JPEG, PNG and WebP images up to 25 MB locally in the browser. Other formats are rejected before editing.
Are the image dimensions and original file retained during export?
The original file remains unchanged. The new export retains the decoded image dimensions and is then re-inspected locally for format, size and changed disclosure pixels.
