Blur Face Online Free With AI
Controls
Faces are blurred automatically after upload. Drag on the image to cover anything the detector misses.
Blur Face automatically finds faces in a photo and softens or pixelates them so people are harder to identify. It is useful for privacy in shared photos, screenshots, event pictures, classroom images, street scenes, or customer content.
You can keep the auto detected face masks, add extra blur for missed areas, and export the edited image without sending it to a server.
How to Use the Blur Face Tool
- Click "Select Image" to upload your photo
- AI automatically detects and pixelates all faces
- Draw over any additional area to blur it manually
- Click "Download" to save the blurred image
