How it works
This tool uses navigator.mediaDevices.getUserMedia() to request access to your webcam. The live video feed is displayed using an HTML5 <video> element. Resolution is read from the video track's videoWidth and videoHeight properties. FPS is measured by counting frames via requestAnimationFrame. All processing happens locally in your browser — no video data is sent anywhere.
Frequently Asked Questions
Is my webcam video sent to any server?
No. This tool runs entirely in your browser using the MediaDevices API. Your video feed is processed locally and never leaves your device. No data is uploaded, recorded on our end, or shared with anyone.
Why is my webcam not working?
Common reasons: 1) You haven't granted camera permission — click 'Allow' when prompted. 2) Another app is using the webcam (close Zoom, Teams, etc.). 3) Your browser doesn't support the MediaDevices API. 4) The webcam is physically disabled or disconnected.
How do I change which camera is used?
If you have multiple cameras (e.g., built-in plus external), you can select the desired camera from the dropdown that appears after granting permission. The tool lists all available video input devices.
What resolution is my webcam recording at?
The tool displays your webcam's active resolution in pixels (width × height). Most built-in laptop webcams record at 720p (1280×720) or 1080p (1920×1080). External webcams may support higher resolutions.
