About This Tool

Why Blur Faces and Sensitive Information?

What Is Image Privacy Blurring?

Privacy blurring is the process of obscuring specific regions of an image to prevent the identification of people, vehicles, or sensitive information. Unlike removing or cropping out content, blurring preserves the overall context and composition of the image while making targeted details unreadable or unrecognisable. It is a widely used technique in journalism, research, social media, and document handling.

When Should You Blur Images?

Faces of unconsenting individuals: When publishing photos of people who have not given consent to be identified — at protests, public events, or in journalistic contexts.
Children in photos: Protecting the privacy and safety of minors by blurring their faces in images shared publicly online.
Licence plates: Blurring vehicle registration plates before publishing street-level photography or traffic incident images.
Sensitive documents: Redacting personal information — account numbers, ID numbers, addresses — from screenshots or document photos before sharing.
Medical and research images: Anonymising patient images in clinical photography and research publications to comply with privacy regulations.
Social media content: Protecting bystanders who appear incidentally in photos you post publicly on Instagram, Twitter, or Facebook.

Choosing the Right Blur Type

Gaussian Blur creates a smooth, soft obscuring effect that looks natural in photographs. It is the most visually pleasing option for faces and backgrounds. Pixelate creates a mosaic effect by replacing the area with large visible pixels — a recognisable and widely understood privacy indicator. Black Out completely covers the area with solid black, providing the strongest possible redaction for text and document information. White Out covers the area with solid white — commonly used in document and form redaction.

Manual vs Automatic Face Detection

This tool uses manual blur zones rather than automatic face detection. While automatic detection is convenient, it can miss faces, misidentify non-face objects as faces, or fail on unusual angles and partial occlusions. Manual blurring gives you complete accuracy and control — you decide exactly which areas to blur and to what extent, ensuring nothing is missed and nothing is incorrectly blurred.

FAQ

Frequently Asked Questions

Common questions about blurring faces and sensitive content with this tool.

Does this tool automatically detect faces?▾

No — this tool uses manual blur zones. You paint the blur yourself using the brush, rectangle, or oval tool. This gives you 100% accuracy and control, since automatic detection can miss faces or blur incorrect areas. For faces, use the Oval tool and cover the face area precisely.

What is the difference between Apply and Download?▾

Blur zones are shown as a preview overlay while you paint. Click "Apply & Save Zones" to bake the blur permanently into the base image. After applying, click Download to save the final image. You can continue adding more zones after applying — they stack on the already-blurred base.

Which blur type should I use for faces?▾

Gaussian Blur and Pixelate are both effective for faces. Gaussian Blur at strength 12-20 creates a natural soft obscuring effect. Pixelate at strength 10+ creates a mosaic effect that is visually distinct and widely understood as a privacy marker. Both are far more reversible-looking than Black Out, which provides the strongest redaction.

Can I undo a blur zone?▾

Yes. Each brush stroke, rectangle, or oval is tracked as a separate zone. Click "↩ Undo" to remove the most recent zone. Click "🗑 Clear All Zones" to remove all unapplied zones and start fresh. Note: once you click "Apply & Save Zones", the blur is baked into the image and cannot be undone without resetting.

Is my image uploaded to a server?▾

No. All processing happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device — no upload, no server, no storage. This makes the tool suitable for handling sensitive, confidential, or private images.

Can I blur text and licence plates too?▾

Yes. The blur tools work on any area of the image — not just faces. Use the Rectangle tool for precise coverage of text, licence plates, ID numbers, or address fields. For complete redaction of text, use Black Out or White Out for maximum concealment.
