Image Censor

Free Online Image Censor & Redaction Tool

Protect sensitive information in your photos and screenshots with our free, browser-based image censor tool. Whether you need to blur a face, pixelate a license plate, or black out confidential text, this image redaction tool gives you professional-grade results without uploading a single file to a remote server.

Choose from five distinct censoring modes—Black Box, White Box, Blur, Pixelate, and Mosaic—to match any use case. Each mode is fully adjustable: set the blur radius, pixel block size, or rotation angle until the censored region looks exactly the way you want. Add multiple regions, resize them with drag handles, and switch between rectangle and ellipse shapes for pixel-perfect coverage.

All processing runs entirely on your device using the HTML5 Canvas API, so your original images never leave your browser. The finished image exports as a high-quality PNG that preserves the full resolution of the original, ready for sharing, printing, or embedding in reports and presentations.

Frequently Asked Questions

Tips & Best Practices

• Use Black Box for text: Solid black provides the most reliable redaction for printed or digital text.
• Choose Blur for faces: A blur radius of 10–15 px hides identity while keeping the photo aesthetically pleasing.
• Increase pixel size for stronger censoring: Larger pixel blocks make it harder to reconstruct the original content.
• Try the ellipse shape: Ellipses follow facial contours more naturally than rectangles.
• Use rotation for angled text: Rotate the censor region to align perfectly with tilted labels or watermarks.
• Always verify before sharing: Zoom in to ensure no sensitive data is visible around the edges of censor regions.
