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

Frequently Asked Questions
Blurring faces or objects hides identifying details by covering them with a strong visual effect so they are harder to recognize. It is commonly used for privacy protection in street photos, event pictures, screenshots, reports, social media posts, and any image where faces, signs, or other sensitive details should not remain visible.
Yes. After upload, the tool uses AI face detection to find visible faces and pixelates them automatically. This helps you hide people quickly without manually drawing every blur area yourself, especially in portraits or group photos.
If a face is missed, you can draw over any area on the canvas to pixelate it manually. The automatic and manual blur modes work together, so you can keep the AI-detected regions and add extra coverage wherever needed.
Yes. The AI is designed to detect multiple faces in the same image and blur each detected face in a single pass. That makes it useful for crowd photos, event images, and group scenes where several people need to be anonymized at once.
The tool uses a strong mosaic-style pixelate effect for both AI-detected faces and manually drawn areas. This type of blur is useful for privacy because it blocks facial details more aggressively than a soft blur effect.
Yes. You can draw over any rectangular area on the canvas, including license plates, addresses, signs, text, screens, or other sensitive objects that the automatic face detector would not target on its own.
Yes. Click Undo to step back through blur actions one at a time, or use Clear All to remove every added blur region and return to the original image state. This makes it easier to refine the result without starting over from scratch unnecessarily.
No. Face detection and blurring happen entirely in your browser using Canvas and the face-api.js library. Nothing is uploaded to a remote server, so your photo stays on your device while you edit and download it.
JPG, PNG, GIF, BMP, and WEBP images are supported for upload. The blurred result is downloaded as a PNG file, which helps preserve the final edited output in a broadly compatible format.
