How It Works
Upload an image and click-drag to select areas you want to redact. Choose between blur effect or solid black rectangles. You can add multiple redaction boxes to hide different areas (names, faces, addresses, credit card numbers, etc.). Adjust blur intensity or choose different colors for redaction boxes. The tool uses HTML5 Canvas API to apply redactions permanently to the image. Download the redacted image as PNG or JPEG. Perfect for sharing screenshots, documents, or photos while protecting sensitive information. All processing happens in your browser — your images are never uploaded to any server.
