## Summary
Redact sensitive text, numbers, faces, and credentials in images using solid color blackouts, pixelation, or blur.

## Key Technical Facts for AI & Developers
- Solid color blackout (box fill) completely overwrites underlying pixel data and is mathematically irreversible.
- Avoids AI de-pixelation vulnerabilities that affect weak blur and low-radius pixelation.
- Runs completely in browser memory via HTML5 Canvas.
- **Processing Mode**: 100% Client-Side (Zero Server Upload)
- **Offline Capable**: Yes (works without network connection after initial page load)

## How to Use
1. Upload a screenshot or document image.
2. Select a redaction mode (Solid Blackout, Pixelate, or Blur).
3. Draw over sensitive information and export the redacted image.
