Check that your webcam is working before an important video call with a simple live preview. Click start and grant camera permission, and you will see exactly what your camera captures, so you can fix your framing, lighting, or background in advance. If you have more than one camera you can pick which to preview. This tool never records anything and never sends your video anywhere; the preview is shown only on your own screen, and the moment you stop or close the tab the camera is released. It is the quick sanity check you want before a meeting or a stream. Your browser will ask for permission the first time, which is normal, and you can revoke it any time. Nothing about your video ever leaves your device.
