The fastest way to test your webcam right now

Open your web browser and go to webcamtests.com or camera-test.com. Both sites ask permission to use your camera, then show you a live feed. If you see yourself on screen, your camera works. If you see a black screen or an error message, your camera is either blocked in your browser settings or not working.

This takes 30 seconds and tells you whether the hardware itself is functioning. If the test fails, the next step depends on what you see — a permission block looks different from a hardware failure, and the fix is different for each.

Most people find the answer this way. If you need to dig deeper — to test in a specific process, check your camera's frame rate, or rule out a driver problem — the sections below walk through each scenario.

Key Takeaways

  • A live-feed test site like webcamtests.com shows in seconds whether your camera hardware is working and whether your browser can access it.
  • A black screen usually means your browser doesn't have permission to use the camera, which you can fix in your browser settings.
  • If the test site works but your video app does not, the problem is in that app's settings, not your camera.
  • Windows users can check the Device Manager to see whether the camera driver is installed and working; Mac users can check System Report.
  • Restarting your computer and closing other apps that use the camera often fixes problems that look like hardware failures.

Testing in your browser versus testing in an app

A browser test tells you whether your camera works at all. An app test tells you whether that specific app can reach it. These are different problems with different fixes.

If webcamtests.com shows your camera working but Zoom or Google Meet does not, your camera is fine — the app either doesn't have permission, is using an old driver, or has a conflicting setting. Close the app completely, restart your computer, and try again. If it still fails, uninstall and reinstall the app.

If the browser test itself fails — you see a black screen or "camera not found" — move to the next section. Your camera either isn't plugged in, isn't turned on (some external cameras have a physical switch), or your browser doesn't have permission to use it.

Fixing a black screen or "camera not found" error

Start with the simplest checks. If you're using an external USB camera, unplug it and plug it back in. Wait 10 seconds for your computer to recognize it. If your laptop has a built-in camera, restart your computer — this resets the camera connection and fixes the problem about half the time.

If you still see black, check your browser's camera permission. In Chrome, click the lock icon next to the web address, then find "Camera" in the list. It should say "Allow". In Firefox, go to Settings, scroll to Permissions, and check Camera. In Safari, go to System Settings (or System Preferences on older Macs), then Security & Privacy, then Camera, and make sure your browser is listed.

If permission is already set to Allow and you still see black, your browser may have crashed or the camera may be in use by another app. Close your browser completely — not just the tab — and open it again. If another app is using the camera (Zoom, Skype, Photo Booth, or even a browser tab you forgot about), close that app first.

Checking your camera driver on Windows

Your camera needs a driver — software that tells Windows how to talk to the hardware. If the driver is missing or broken, Windows can't see the camera even if it's plugged in.

Press the Windows key and type "Device Manager", then open it. Look for "Cameras" in the list. Click the arrow next to it to expand. You should see your camera's name. If you see a yellow exclamation mark or a red X next to it, the driver is broken or missing.

Right-click the camera name and select "Update driver". Choose "Search automatically for updated driver software". Windows will search online and install the latest version. Restart your computer when it finishes. If that doesn't work, right-click again and select "Uninstall device", then restart your computer. Windows will reinstall the driver automatically on startup.

If you don't see "Cameras" in Device Manager at all, your camera may not be recognized by Windows. Unplug the camera, wait 30 seconds, and plug it back in. If it still doesn't appear, the camera may be broken or your computer's USB port may not be working.

Checking your camera on Mac

Open System Report by clicking the Apple menu, selecting "About This Mac", then clicking "System Report". Click "Hardware" on the left, then scroll down to "USB" or look for your camera in the list. You should see your camera listed with a status. If it's not there, your camera isn't being recognized.

If your camera is listed but isn't working, restart your computer. If that doesn't fix it, open System Settings, go to Security & Privacy, then Camera, and check that the apps you want to use have permission. Remove and re-add them if needed.

For built-in cameras on Mac, the driver is part of the operating system. If your camera isn't working and it's built in, restart your computer first. If that fails, a macOS update may be needed — go to System Settings, General, Software Update, and install any available updates.

Testing camera frame rate and resolution

If your camera works but video looks choppy or blurry, you may want to check its frame rate (how many images per second it captures) and resolution (how many pixels). Most webcams run at 30 frames per second and 1080p resolution, which is fine for video calls. Older or cheaper cameras may run at 24 fps or 720p, which looks noticeably worse.

On Windows, open Device Manager, right-click your camera, select "Properties", then click the "Driver" tab and select "Driver Details". This shows the driver version but not the frame rate. For frame rate and resolution, you need to check your camera's manual or the manufacturer's website — the specs are usually listed there.

On Mac, open System Report, find your camera in the USB list, and click it. The information shown includes the camera model but usually not the frame rate. Check the manual or manufacturer's website for those specs.

If you want to test frame rate in real time, some video apps show it. In Zoom, start a test meeting, click "Video Settings", and look for a frame rate display. In OBS Studio (free software used for streaming), you can see frame rate in the bottom right corner of the window.

What to do if your camera works in one app but not another

This almost always means the app that's failing doesn't have permission, or it's trying to use the camera while another app is already using it. Cameras can usually only be used by one app at a time.

Close the app completely — not just minimize it. On Windows, press Ctrl+Alt+Delete, open Task Manager, find the app in the list, and click "End Task". On Mac, press Command+Q while the app is in focus. Then restart your computer and try the app again.

If it still fails, check the app's settings. In Zoom, go to Settings, click "Video", and make sure "Camera" is set to your camera (not "None"). In Google Meet, click your profile picture, select "Settings", click "Audio and video", and check that your camera is selected. In Microsoft Teams, click your profile picture, select "Settings", click "Devices", and check Camera.

If the app still can't find your camera, uninstall and reinstall it. This usually fixes permission problems that settings alone won't solve.

Frequently Asked Questions

Why does my camera work in one browser but not another?

Each browser has its own camera permission settings. Chrome, Firefox, Safari, and Edge each maintain a separate list of which websites can use your camera. If your camera works in Chrome but not Firefox, check Firefox's camera permission in Settings > Privacy & Security > Permissions > Camera. You may need to allow the website again.

Can I test my camera without giving a website permission to use it?

On Windows, you can open the Camera app (search for "Camera" in the Start menu) to see a live feed without visiting a website. On Mac, open Photo Booth (in Applications > Utilities) for the same result. Both show whether your camera hardware is working without requiring browser permissions.

What if my external camera is plugged in but Windows doesn't see it?

Try a different USB port on your computer. Some ports may not be working, or your camera may need a powered USB hub instead of plugging directly into your computer. If you have a powered hub, plug the camera into that and plug the hub into your computer. If it works, your computer's USB ports may not supply enough power.

Is it normal for my camera to show a green light when I'm not using it?

A green light usually means the camera is on and ready to use, not that it's actively recording. Some cameras show a light whenever they're powered. If you're concerned about privacy, you can cover the camera with a small piece of tape when you're not using it, or unplug an external camera.

Why does my camera work fine in video calls but look blurry in photos?

Video calls often use lower resolution to save bandwidth, so blurriness in photos usually means your camera's autofocus isn't working or the lens is dirty. Clean the lens gently with a soft, dry cloth. If it's still blurry, your camera may have a focus ring (a small rotating ring around the lens) — try adjusting it slightly. If neither works, the camera's autofocus may be broken.
