About the webcam test

The webcam test asks your browser for camera access and shows the live feed instantly, along with the camera’s name and the resolution of the stream. It answers the question most people arrive with — "is my camera actually working?" — in about five seconds, without installing anything.

The video never leaves your device. The preview is rendered locally by your browser; this site has no recording, storage or streaming component, and closing the tab ends the camera session completely. That local-only design is exactly why it is safe to use as a quick mirror before joining a meeting.

The test is most valuable for narrowing down where a fault lives. If the preview works here but Zoom, Teams or Meet shows a black square, your camera hardware and drivers are fine — the meeting app has a permissions or device-selection problem. If the preview fails here too, the issue is lower down: browser permission, OS privacy settings, or another app holding the camera.

How to judge your webcam preview

A successful test shows a live preview, the selected camera and the stream resolution. Use it to decide whether the issue is camera access, camera quality or the app you normally use.

Good

A sharp, smooth preview appears within a couple of seconds, the correct camera is selectable by name, and the reported resolution matches what the camera should deliver.

Average

The preview works but looks dark, grainy or lower-resolution than expected. That is usually lighting, a conservative browser stream choice or an ageing sensor rather than a fault.

Poor

No preview at all: permission denied, a black frame, or a "camera in use" error. Work through the fixes below — in most cases another app or a privacy setting is holding the camera.

What this test checks

  • Browser permission for camera access on this site.
  • Whether a live video stream can start without another app blocking the webcam.
  • Selected camera device and basic stream resolution reported by the browser.
  • Mirror mode, which changes only the local preview and does not alter the camera hardware.

How to understand your results

  • If the preview is sharp and stable here, your camera hardware is probably working and the problem may be in Zoom, Teams, Meet or another app.
  • A dark picture usually means lighting or exposure is the issue. Face a window or add a lamp before changing drivers.
  • A low resolution can be normal for older built-in webcams or when the browser chooses a conservative stream.
  • If the preview freezes, close other camera apps and retest after refreshing the browser.

Common problems and fixes

Permission denied

Use the browser site settings to allow camera access, then refresh the page and start the test again.

Camera busy

Close meeting apps, recording software and other browser tabs that may already be using the camera.

Wrong camera selected

Open the device list after permission is granted and choose the built-in or external camera you actually want.

Poor image quality

Improve lighting, clean the lens and check whether the camera is using privacy shutter, low power mode or a poor USB hub.

FAQ

Is my video uploaded?

No. The preview is displayed locally in your browser session. The site does not record or store your camera feed.

Why are camera names hidden at first?

Browsers often reveal full device labels only after permission is granted.

Does mirror mode affect other apps?

No. It only flips the preview on this page so you can view yourself comfortably.

Why is my webcam black in Zoom but working here?

The hardware is fine. In the meeting app, check its own camera permission in system privacy settings and its selected device — it may be pointing at a virtual or disconnected camera.

How do I test an external USB webcam?

Plug it in before opening the test, grant permission, then pick it from the device list. If it never appears, try another USB port and avoid unpowered hubs.

What resolution should my webcam show?

Most built-in laptop cameras are 720p and many external ones are 1080p or higher. Browsers sometimes open a lower-resolution stream by default, so a lower figure here is not proof the camera is limited.
