Inspecciona C2PA Content Credentials, prompts y EXIF con 100% de privacidad.
Helpful External Verification Tools
Cross-verify your sanitized files using independent third-party validators and official C2PA tools.
Content Credentials Verify
The official C2PA coalition validator. Upload your file to verify zero digital certificates or provenance survives.
Metadata2Go
Inspect raw EXIF, XMP, and IPTC blocks online to inspect camera optics and ensure prompt seeds are cleared.
Hive Moderation AI Detector
Test AI detection scores on before and after images to verify synthetic markers were removed.
Sightengine AI Detection
Verify AI probability reduction and visual texture integrity after UnlabelAI pixel blending.
To verify metadata removal on your local machine with 100% cryptographic certainty, run ExifTool from your command line:
Confirm that all [XMP-c2pa], [Photoshop], and [PNG-tEXt] tags are gone, and authentic camera optics match your selected profile.
What Social Ingestion Bots Check For
Every major social platform automatically scans your upload payload in fractions of a second.
1. C2PA JUMBF Manifests
Coalition standards embed cryptographic certificates signed by Adobe, OpenAI, or Microsoft. If found, Meta and TikTok immediately apply automated badges.
2. Embedded Generation Prompts
Stable Diffusion and ComfyUI write full prompt strings, seeds, and workflow trees into file chunks, leaving unmistakable synthetic fingerprints.
3. Empty Optical Headers
Legitimate camera photos always carry shutter speed, aperture, and sensor profiles. Completely stripped files trigger heuristic algorithms to inspect pixels.
Frequently Asked Questions
What is an AI metadata checker?
An AI metadata checker is a privacy and verification tool that scans image file headers for embedded synthetic indicators, including C2PA Content Credentials, Adobe XMP packets, generation prompts (Midjourney, DALL-E, Stable Diffusion), and camera EXIF data. It helps you see what social media ingestion algorithms see before you publish.
How does this tool detect C2PA Content Credentials?
UnlabelAI reads the raw binary buffer of your image directly in your browser memory. It searches for JUMBF (JPEG Universal Metadata Box Format) boxes, C2PA assertions, and CAI digital certificates without uploading your image to any external server.
Will checking my image alert social media platforms or AI detectors?
No. UnlabelAI runs 100% locally inside your web browser using client-side JavaScript. Zero bytes of your file or its metadata are sent to any remote server or cloud service.
What should I do if C2PA credentials or AI prompts are found?
If synthetic markers are detected, you can click "Clean Image" directly within the checker or use our in-browser Remover tool. UnlabelAI strips 100% of C2PA manifests, disrupts watermark frequencies, and attaches authentic camera metadata.
Can this checker inspect PNG and WebP files too?
Yes. The checker natively parses JPEG, PNG (including tEXt, iTXt, and zTXt chunks), and WebP files up to 50MB.
Need to remove AI metadata from your files?
Use our in-browser AI Metadata Remover to strip C2PA manifests and inject genuine camera optics in seconds.
