Webcam test
Check your camera before a call rather than during one. The picture below is exactly what the other end would receive, and the details underneath show the resolution and frame rate actually being produced.

Not started.
Your browser will ask permission to use the camera when you start the test. Nothing is captured before you allow it, and nothing leaves your device afterwards.
Resolution is negotiated, not fixed
A camera advertised as 1080p will happily deliver 640×480 if the browser, the lighting or the available bandwidth suggests it. The figures under the preview are what your camera is really producing right now, which is often lower than the box claimed.
Lighting beats hardware
A cheap camera in good light looks better than an expensive one in bad light. The single biggest improvement available to most people is a light source in front of them rather than behind — sitting with a window at your back turns you into a silhouette no camera can fix.
Nothing here leaves your device
Every one of these tests runs entirely in your browser using standard web APIs. No audio, video, keystroke or controller input is uploaded, recorded on a server, or stored anywhere — there is no upload endpoint for any of it to go to. Closing the tab discards everything.
Common questions
How do I know if my webcam is working?
Allow camera access and look at the preview. If you can see yourself, the camera works and the problem in your video call is with that application rather than the hardware.
Is the video recorded or sent anywhere?
No. The preview is rendered locally in the page and nothing is transmitted or stored. Closing the tab ends it.
