## 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.
