Processing Time
First use may take longer as the AI model loads. Subsequent uses are faster as the model is cached.
Privacy Considerations
- All processing happens locally
- AI model runs in your browser
- No images are uploaded
- No facial data is stored
Tips
- Higher blur for better anonymity
- Check all faces were detected
- Reprocess if faces were missed
- Combine with crop to remove context
Privacy
All face detection and blurring happens locally in your browser. Your images and facial data are never uploaded to any server.
