The fastest way to test your webcam right now

Open your web browser and go to webcamtests.com or camera-test.com. Both sites let you test your webcam in seconds without installing anything. Click the button to start the test, allow the browser to access your camera when it asks, and you'll see a live video feed from your webcam. If you see yourself on screen, your webcam is working. If you see a black screen or an error message, move to the troubleshooting sections below.

These sites work on Windows, Mac, and Linux, and they work in any modern browser. You don't need to create an account or read software. The test takes about 30 seconds.

Key Takeaways

  • The quickest test is a free online camera test site like webcamtests.com, which shows you a live feed in your browser.
  • If the browser asks for permission to use your camera and you deny it, the test will fail even if your camera works—check your browser settings.
  • Windows users can also open the Camera app from the Start menu to test the webcam without leaving your computer.
  • If you see a black screen or error, check that no other program is using the camera, restart your computer, and update your camera drivers.
  • A physical obstruction like a sticker or dust cover will block the camera even if the hardware is working—remove it and test again.

Testing your webcam in Windows using the built-in Camera app

Windows 10 and Windows 11 both include a Camera app. Open the Start menu, type "Camera," and click the Camera app when it appears. The app will ask for permission to use your camera. Click "Yes" to allow it. If your camera works, you'll see a live video feed of yourself within a few seconds.

If you see a black screen, the app may be blocked by your privacy settings. Go to Settings > Privacy & Security > Camera, and make sure the toggle next to "Camera access" is turned on. Also check that the Camera app itself has permission—scroll down to "Allow apps to access your camera" and make sure Camera is listed and enabled.

Testing your webcam on Mac

Open Finder and go to Applications > Utilities > Photo Booth. This built-in app uses your webcam to take photos and record video. When you open it, you should see a live preview of your camera feed. If Photo Booth shows your face or the room behind your computer, your webcam is working.

If you see a black screen or a message saying the camera is not available, your camera may be blocked by privacy settings. Go to System Settings > Privacy & Security > Camera, and check that Photo Booth (or the app you're trying to use) is listed and has permission. You may need to restart Photo Booth after changing these settings.

Checking browser permissions when the test site shows a black screen

When you visit a camera test site, your browser will ask "Allow this site to access your camera?" If you click "Block" or "Don't Allow," the site cannot use your camera even if it works. This is a security feature—websites cannot secretly access your camera.

If you blocked the site by accident, you need to clear that decision. In Chrome, click the lock icon in the address bar, find "Camera," and change it from "Block" to "Allow." In Firefox, go to Preferences > Privacy & Security, scroll to Permissions, find Camera, and remove the site from the blocked list. Then reload the test site and click "Allow" when asked.

On Mac, if you see a message that the app does not have permission, go to System Settings > Privacy & Security > Camera and add the browser to the list of apps allowed to use the camera.

What to do if another program is using your camera

Some programs lock exclusive access to your webcam while they're running. If Zoom, Skype, Teams, or another video app is open, close it completely before testing. Don't just minimize it—fully quit the program. Then try the camera test again.

On Windows, you can also check which programs are using your camera. Open Settings > Privacy & Security > Camera, scroll to "Allow apps to access your camera," and look for any app with a green checkmark and a recent timestamp. Close that app and test again.

Restarting your computer and updating camera drivers

If the test site still shows a black screen after checking permissions and closing other apps, restart your computer. Many camera problems are temporary and disappear after a restart. Shut down completely, wait 10 seconds, and turn the computer back on. Then test the camera again.

If restarting doesn't work, your camera driver may be outdated or corrupted. On Windows, open Device Manager by right-clicking the Start menu and selecting Device Manager. Look for "Cameras" in the list, click the arrow to expand it, right-click your camera, and select "Update driver." Choose "Search automatically for updated driver software" and let Windows install any updates it finds. Restart your computer and test again.

On Mac, camera drivers are built into the operating system and update automatically. If your Mac camera isn't working after a restart, go to System Settings > General > Software Update and install any available updates. Restart and test again.

Physical checks: lens obstruction and hardware damage

Before assuming your camera is broken, check the lens itself. Look at the small camera lens on your laptop, monitor, or external webcam. Is there a sticker, dust cover, or piece of tape over it? Remove anything blocking the lens and test again. Many people forget they covered their camera for privacy and think it's broken.

Wipe the lens gently with a soft, dry cloth to remove dust or fingerprints. If your webcam is external (plugged in with a USB cable), try unplugging it, waiting 10 seconds, and plugging it back in. If it's built into your laptop and still shows a black screen after all the steps above, the camera hardware may be damaged and you may need to contact the manufacturer or a repair technician.

Frequently Asked Questions

Why does the camera test site show a black screen even though I clicked Allow?

Check that no other video app (Zoom, Skype, Teams) is running—they often lock the camera so other programs can't use it. Close all video apps completely, not just minimized. Also check for a physical obstruction like a sticker or dust cover over the lens. If both are clear, restart your computer and try again.

Can I test my webcam without using a website?

Yes. Windows users can open the Camera app from the Start menu. Mac users can open Photo Booth from Applications > Utilities. Both show a live video feed if your camera works. These built-in apps don't require internet and are just as reliable as online test sites.

What if my camera works in one app but not another?

The app that doesn't work may not have camera permission. Go to your privacy settings (Settings > Privacy & Security > Camera on Windows, or System Settings > Privacy & Security > Camera on Mac) and make sure the app is listed and enabled. You may need to restart the app after changing permissions.

Is my webcam broken if it shows a black screen after trying everything?

Not necessarily. Try one more restart and check that no sticker or cover is blocking the lens. If the camera still shows black after that, the hardware may be faulty. Contact the computer manufacturer or a repair technician. If it's an external USB camera, try it on a different computer to see if the problem follows the camera or stays with your computer.

Do I need to install software to test my webcam?

No. Free online test sites like webcamtests.com work in any browser without installation. Windows and Mac also have built-in camera apps (Camera on Windows, Photo Booth on Mac) that require no read. You don't need to install anything to check if your webcam is working.
