Blur Faces & Redact Sensitive Text in Images

How to Use AI Privacy Censor ULTRA MAX

• Step 1: Upload Your Image
  Drag and drop any JPG, PNG, WEBP, or BMP image into the upload zone, or click to browse your files. Your image never leaves your device.
• Step 2: Choose Censor Modes
  Enable AI Face Censor to auto-detect faces, OCR Text Redact to find emails/phones/cards, and Magic Brush for manual painting. Mix and match as needed.
• Step 3: Run AI Censor
  Click "Run AI Censor" to trigger the MediaPipe face model and Tesseract OCR engine. Results appear live on the canvas.
• Step 4: Refine with Magic Brush
  Enable the Magic Brush and paint over any remaining areas you wish to censor. Use the Undo button to reverse strokes.
• Step 5: Download Clean Image
  Hit "Download Image" to export a privacy-cleaned PNG with all EXIF metadata stripped. Your original file is untouched.

Technology Stack: How It Works

This tool uses a cutting-edge stack of browser-native AI libraries to process everything locally:

• MediaPipe Tasks Vision (Face Detector): Google's production-grade ML model runs entirely via WebAssembly in your browser, detecting face bounding boxes with sub-100ms latency.
• Tesseract.js (OCR Engine): A WebAssembly port of the industry-standard Tesseract 4 OCR engine. It reads image text and our regex engine flags sensitive patterns (emails, phone numbers, 16-digit card numbers).
• HTML5 Canvas API: All blur, pixelation, and black-bar effects are rendered via raw Canvas 2D context operations — no server-side image processing whatsoever.
• JSZip + FileSaver.js: Batch output is packaged into a ZIP archive entirely in memory and triggered as a browser download with zero server involvement.
• EXIF Stripping: By re-drawing source images onto a fresh Canvas and exporting as PNG blob, all EXIF metadata (GPS, camera model, timestamps) is inherently discarded.

Privacy & Security Guarantee

This tool operates 100% Client-Side. Every byte of AI processing happens within your browser's sandboxed environment:

• Your images are never uploaded to any server.
• No image data, metadata, or OCR results are ever logged or transmitted.
• AI models are loaded from public CDNs once and cached by your browser.
• Works fully offline after the first load (models cached via browser storage).
• EXIF stripping ensures exported images contain zero geolocation or device fingerprint data.

Disclaimer

AI face detection may not catch all faces in low-resolution, extreme-angle, or occluded images. OCR accuracy depends on image quality and font clarity. Always manually review the canvas output before sharing sensitive documents. This tool is provided for legitimate privacy protection purposes only.
