How to Test Your Webcam Online (Free & Private)

Quick answer: To test your webcam online, open a browser webcam test, click start, and allow camera access. If you see a live preview of yourself, your webcam works. A good test runs entirely in your browser, so nothing is recorded or uploaded.

Try it now: open the webcam test , click start, and allow access when your browser asks. You should see yourself within a second or two.

How to test your webcam in three steps

1. Open the test and click start

Go to the webcam test and press start. There is nothing to download or install — it runs in the browser.

2. Allow camera access

Your browser shows a permission prompt near the address bar. Click Allow. The test cannot see your camera until you grant access, which is why you stay in control.

3. Check the preview

You should see a live image of yourself. Use it to check framing and lighting, and note the resolution and frame rate shown — that is what apps like Zoom will receive.

Is the webcam test private? Does it record me?

Yes, it is private. A browser-based test displays the camera feed only on your own screen — it does not record, upload, or store any video, and only you can see the preview. Any test photo you take is created in your browser and stays there unless you choose to save it.

Why is my webcam preview black?

A black preview almost always means one of four things: a physical privacy shutter is closed, another app (Zoom, Teams, OBS, or an old browser tab) is already holding the camera, the browser permission is set to Block, or the system camera privacy toggle is off. Open the shutter, close other video apps, allow access from the camera icon in the address bar, and check Settings → Privacy & security → Camera on Windows. Refresh, and restart the browser if needed.

My webcam works here but not in Zoom or Teams

If the preview works in the test but the app shows nothing, the camera is fine — the app has the wrong camera selected or lacks permission. Pick the right device in that app's video settings. For a camera Windows will not detect at all, see our guide on a webcam not detected on Windows .

Can I test my webcam on a phone?

Yes. A browser-based webcam test works on any phone or tablet — open it in your mobile browser, allow camera access, and the front or rear camera preview appears.

Confirm your webcam works

Once you see a clear live preview on the webcam test , your camera is working and your browser has permission. If it fails only in one app, the fix is in that app's settings.
