About this tool
What does Blur Faces / Privacy Mask do?
Blur Faces / Privacy Mask helps hide faces, license plates, addresses, screens and other identifying details before an image is shared. Automatic face detection uses a browser-loaded model when available. Manual rectangle selection remains available for any object and is essential for verifying missed areas.

Step-by-step guide
How to use Blur Faces / Privacy Mask
- Upload the image that contains sensitive details.
- Run face detection or draw manual rectangles.
- Choose blur, pixelation or solid mask strength.
- Inspect every area carefully and download the protected copy.
Understand the result
How to read and refine the output
Automatic detection is a starting point, not a privacy guarantee. Review reflections, background faces, license plates, documents and screens manually. Strong pixelation or solid masks are harder to reverse visually than a light blur.
Practical advice
Tips for better results
- Use solid masks for highly sensitive information.
- Check the full-resolution output, not only the thumbnail.
- Add manual regions for missed faces and plates.
- Keep the unredacted original in secure storage.
Best-fit tasks
When to use Blur Faces / Privacy Mask
- Masking faces before public posting
- Hiding addresses, license plates, badges and screens
- Creating a cleaned copy for support tickets or social sharing
Choose carefully
When another method may be better
Automatic detection is not a guarantee. For highly sensitive material, manually inspect every region and prefer an opaque mask when underlying text must be visually unrecoverable.
Practical example
Example workflow
After automatic face detection, manually scan corners, reflections and text labels, add masks where needed, export a copy and inspect it again at full size.
Important limitations
What this tool cannot guarantee
Face detection can miss profiles, small faces, masks and unusual lighting. Blur may leave recognizable shapes, and no browser tool can guarantee anonymization against every reconstruction technique. Manual review is required.
Common questions
Blur Faces / Privacy Mask FAQs
Is automatic face detection guaranteed?
No. Always review the image and add manual masks for missed areas.
Which mask is safest?
An opaque solid mask usually reveals less visual information than a light blur.
Can I hide license plates?
Yes. Draw a manual rectangle over each plate.
Does detection send faces to a server?
No. The model runs in the browser after its files are loaded.
