Blur Faces in Video
Anonymize people automatically: an on-device AI model finds every face frame by frame and applies an elliptical blur. Nothing is uploaded anywhere.
Per-frame AI detection
A neural face detector runs on every frame in WebAssembly, so faces stay blurred even as people move.
Elliptical, padded masks
Masks extend beyond the detection box and use a soft elliptical clip, so hairlines and chins stay covered.
Privacy by architecture
The whole point is anonymity — so the processing itself never leaves your machine.
How to blur faces in a video
- Open the tool and add your video. Open Pixlane Blur Faces in Video and drop your MP4 or MOV (or choose a file). It loads instantly and is processed on your device — nothing is uploaded.
- Adjust. Set the blur strength — the on-device AI detects and blurs every face on every frame.
- Export and download. Click Blur & export and download the result — free, no watermark, no signup.
Frequently asked questions
Does it track faces between frames?
Detection runs on every frame; brief single-frame dropouts are bridged with the last known positions.
Why is there a 30-second cap?
Per-frame neural inference is heavy. Split longer footage with Trim Video first, then blur each part.
Can I choose the blur amount?
Yes — light, medium, or strong.
Will it blur faces that turn away or are partly hidden?
Front and three-quarter faces are detected reliably; fully turned-away heads may be missed on some frames, so use strong blur and check the preview.
Is this enough for GDPR or anonymization?
It automates most face anonymization, but always review the result — you remain responsible for confirming every face is covered before publishing.
