How to Use Blur License Plates in Video
- Upload a video (MP4, MOV, WebM, MKV)
- Pick a privacy strength — solid color, pixelate, or soft blur
- Click Process — the AI tracks every plate and redacts them
- Download the anonymized video
Features
- Three privacy modes — solid color (maximum), pixelate (mosaic), or soft Gaussian blur
- Auto-detects every license plate across every frame
- Our AI video tracker keeps plates masked even as cars move
- Audio preserved
- Tight per-plate redaction — adjacent cars stay distinguishable
- No sign-up, no watermark on the output
Frequently Asked Questions
- What's the difference between solid, pixelate, and soft blur?
- Solid fills each plate with a flat black bar across every frame — strongest privacy. Pixelate applies tracking mosaic blocks. Soft blur is the lightest — plate stays visible as a shape but the characters are obscured. For dashcam uploads going to YouTube / social, solid is the safest because soft-blur can occasionally leave a plate readable in a single frame.
- How long can the video be?
- Up to 10 seconds for free users. Pro plans extend this limit. The AI tracker maintains plate identity across frames within a 10-second window; longer clips are processed in chunks.
- Will adjacent cars in traffic get merged into one blur?
- No. Plate detection is per-plate — we use just 4px of mask dilation so each plate stays an independent redaction region. Even cars side-by-side in heavy traffic stay individually redacted.
- Is the audio preserved?
- Yes — the original audio track is muxed back into the output video.
