Privacy Effects Explained
Blur Effect
Applies a Gaussian blur that softly obscures facial features. Best for social media posts where you want to protect privacy while keeping a natural look. Adjustable from subtle (10) to heavy (50) blur intensity.
Pixelate Effect
Creates the classic mosaic/pixel censorship look familiar from news broadcasts and documentaries. The block size adjusts from small pixels (more recognizable) to large blocks (more anonymous).
Black Box Effect
Covers the selected area with a solid black rectangle or ellipse. This provides the highest level of privacy protection since no facial data remains. Recommended for legal documents, evidence photos, or maximum anonymization.

Common Use Cases
Social Media Privacy
Blur faces of strangers in background of your photos before posting to Instagram, Facebook, or TikTok. Protect others' privacy without ruining your shots.
GDPR Compliance
Anonymize photos for business use to comply with GDPR, CCPA, and other privacy regulations. Essential for marketing materials with crowd shots.
Real Estate Photography
Blur faces of people in property photos or street views. Protect tenant privacy while showcasing listings.
Journalism & Documentation
Protect sources and witnesses in news photography. Pixelate or black out faces to maintain anonymity in sensitive reporting.
Privacy Note
For maximum privacy protection, consider using the Black Box effect instead of blur or pixelate. Modern AI algorithms can sometimes reverse-engineer blurred or pixelated faces. Solid black coverage provides the highest level of anonymization.
Frequently Asked Questions
Is this face blur tool really free?
Yes, completely free with no limits. No signup required, no watermarks added, and no premium tier needed. Use it as much as you want.
Are my photos uploaded to a server?
No. All processing happens directly in your browser using client-side JavaScript. Your images never leave your device—they're not uploaded, stored, or transmitted anywhere. This is the safest way to handle sensitive photos.
What's the difference between blur and pixelate?
Blur applies a smooth Gaussian blur that softens the image. Pixelate creates blocky mosaic squares (like you see on TV news). Both hide identity, but pixelate has a more obvious "censored" look while blur appears more natural.
Can I blur multiple faces in one photo?
Yes. Draw as many blur regions as you need. Each region can cover a different face. Great for group photos, crowd shots, or images with multiple people to anonymize.
Which effect provides the best privacy protection?
Black Box provides the strongest privacy protection since it completely covers the face with solid color. Blur and pixelate can theoretically be reversed by advanced AI in some cases, though this is uncommon.
What image formats are supported?
The tool supports JPG/JPEG, PNG, WebP, and most common image formats. The output is saved as a high-quality PNG to preserve the blur effect without compression artifacts.
Does this tool have automatic face detection?
Currently, this tool uses manual selection for maximum control and privacy. You draw the blur regions yourself, ensuring you blur exactly what you want. This approach also means no AI processing of your faces.
