Detect visible faces in a photo before sharing it publicly or using it in a presentation.

Face detection and image processing run in your browser. The source image is not uploaded to Zavilo for this tool.
About AI Face Blur
AI Face Blur uses an on-device face detector to locate faces automatically, then applies blur or mosaic with browser image processing. It is designed for quickly obscuring visible faces before sharing screenshots, event photos or other images.
Common use cases
Street and event photos
Apply blur or mosaic to multiple detected faces without manually drawing every region first.
Create anonymized working copies
Make a derivative image that reduces facial visibility while retaining the overall scene.
How it works
1
A browser vision model scans the selected image for face-like regions.
2
Detected face boxes are shown so you can review the proposed regions.
3
The selected blur or mosaic effect is rendered over those regions in the output image.
Privacy & file handling
Face detection is browser-side
The supported face-detection workflow analyzes the image on the device instead of requiring the source photo to be uploaded to Zavilo.
Limitations and important notes
- Small, rotated, partially covered or unusual faces may not be detected.
- False positives are possible, so inspect every detected region before export.
- Blurring a face does not remove other identifying details such as clothing, tattoos, location or metadata.
Automatic face blur vs manual mosaic
| Feature | Advantage | Use when |
|---|---|---|
| AI Face Blur | Finds likely faces automatically | Many visible faces need a quick first pass |
| Mosaic / Blur Image | Lets you select any region manually | You need to hide plates, documents or regions the face model does not detect |
How to use AI Face Blur
- 1
Choose a JPG, PNG or WebP image.
- 2
Wait for the browser face detector to locate visible faces.
- 3
Choose Blur or Mosaic and adjust the effect strength.
- 4
Review every detected area and make sure all sensitive faces are covered.
- 5
Download the protected image as PNG.
Tips for better results
- Automatic face detection can miss very small, heavily rotated, covered or blurred faces, so always review the result.
- Use a stronger effect when the source image contains high-resolution faces.
- Keep the original file separately because the downloaded copy permanently alters the detected face areas.
Frequently asked questions
Which file formats can I use?
Check the file picker and tool description for the supported formats. Available formats can vary by tool.
Will it detect every face?
No detector is perfect. Small, occluded, sideways or low-quality faces may be missed, so the result should always be checked before sharing.
What is the difference between blur and mosaic?
Blur softens facial detail, while mosaic replaces detail with larger pixel blocks. Both are visual hiding methods rather than cryptographic anonymization.
