Webcam Test
Check your camera works, see the real resolution and frame rate, and pick the right device.
Not started.
The worst time to discover your camera is not working is four minutes into a call. Worse is the case where it works but the wrong camera is selected — the one built into the lid rather than the good one on the desk — and nobody tells you for twenty minutes.
This page opens the camera, shows the resolution and frame rate that are actually arriving rather than the ones you asked for, and lets you switch between devices. A snapshot button proves the image is real. Nothing is recorded and nothing is uploaded: the video stream goes from the camera to the video element in this tab and nowhere else.
How to use it
- Press Start camera and allow access when the browser asks. Permission is per-site, so you only do this once.
- Pick the camera from the device list. If the list shows generic names, allow access first — browsers hide labels until permission is granted.
- Choose a resolution and frame rate to check what the camera will actually deliver. Many webcams advertise 1080p but only manage 30 fps at 720p.
- The measured frame rate under the picture is what is genuinely arriving, which is the number that matters on a call.
- Tick Mirror if you prefer the selfie-style reflection — it affects the preview and the snapshot, so it is a real choice rather than cosmetics.
- Take a Snapshot to save a PNG and confirm the image is sharp, then press Stop to release the camera.
Questions
Why does the camera list show names like 'Camera 1'?
Browsers deliberately hide device labels until the page has permission, because the labels can be used to fingerprint a machine. Start the camera once and the real names appear.
The picture is dark or grainy. Is that the tool?
No. That is the sensor being short of light, which is the single most common reason a webcam looks bad. Camera quality is set by the hardware and by the light in front of you; a tool cannot add brightness without washing the image out.
Is the video being recorded or sent anywhere?
No. The stream is attached directly to the video element on this page. There is no recording, no upload and no analytics on the picture. You can confirm it yourself with your browser's developer tools — the only network requests are for the page's own files.
