Why Use Untrace?

Modern images contain hidden data that can compromise your privacy:

• Location data reveals where photos were taken
• AI signatures show which tools generated images (DALL-E, Midjourney, ChatGPT, Stable Diffusion)
• C2PA content credentials track the entire creation and editing history
• Device info identifies your camera/phone
• Timestamps reveal when images were created
• JUMBF containers store complex metadata structures
• Content Authenticity markers link images to specific AI tools
• Provenance data creates a digital paper trail

Untrace removes all this data while keeping your images looking exactly the same.
