Webcam Not Working? Troubleshooting Tips
If the online camera test can't see your device, walk through these fixes in order.
Camera permission denied
Open your browser's site settings, set Camera to Allow for this page, then reload and run the webcam test again.
Browser can't find your webcam
Close other apps that may be holding the camera (Zoom, OBS, Teams) and re-run the camera test.
Update webcam drivers
On Windows, open Device Manager → Cameras → Update driver. On Mac, run macOS updates. Then retry the webcam test.
Try a different browser
If the camera test still fails, try Chrome or Edge they have the broadest webcam support.
Still stuck? Check what the browser is allowed to use with the Permissions Test, confirm the hardware is visible with Connected Devices, and rule out audio problems with the Microphone Test and Speaker Test.
How to Fix Camera Not Working
If the webcam test shows a black screen, "no camera found", or nothing at all, the cause is almost always permissions, another app holding the device, or a driver problem. Start with the quick fixes below, then read the full step-by-step guide.
Check camera permissions
Open the padlock icon in your address bar and make sure Camera is set to Allow for this site, then reload and run the webcam test again.
Close other apps using the camera
Zoom, Teams, OBS and other video apps can lock the webcam. Quit them fully, then re-run the camera test to see if your device appears.
Update or reinstall the driver
On Windows use Device Manager to update or reinstall the camera driver. On Mac run system updates. A restart often fixes detection issues.
More About Our Webcam Tester
Numbers, capabilities and the tech behind one of the fastest camera tests on the web.
A real diagnostic, not a fake mirror
Most "webcam test" sites just show your face in a <video> tag. We go further sampling live frames on a canvas to compute brightness, saturation, dominant hue and an actual measured frame rate, then cross-check them against your camera's advertised capabilities.

Understanding Webcam Specifications
The camera test reports several numbers. Here is what each one means and why it matters for your calls, streams and recordings.
Resolution (720p / 1080p / 4K)
Resolution is the number of pixels the camera delivers, written as width x height. 720p (1280x720) is the floor for video calls, 1080p (1920x1080) is the clear-call standard, and 4K (3840x2160) is only useful for streaming or recording if your platform and connection support it. Most call apps cap you at 1080p anyway.
Frame rate (FPS)
Frames per second is how many images the camera sends each second. 30 FPS is smooth enough for normal calls; 60 FPS looks noticeably sharper when you move. Below 24 FPS the picture looks jerky. The camera test measures real FPS, which can be lower than the camera's rated FPS when the USB port, lighting or CPU can't keep up.
Megapixels
Megapixels describe the sensor's maximum pixel count, not what you see on screen. A 1080p picture is about 2 megapixels. Higher megapixel sensors (4MP, 8MP) give more detail when you crop or zoom, but megapixels alone don't guarantee a better image. Lens quality, sensor size and lighting matter more than the number.
Field of view (FoV)
Field of view is how wide an angle the lens captures. A narrow FoV (60-70 degrees) frames one person tightly with less background noise. A wide FoV (90 degrees or more) fits a group or a room but can distort the edges (the fish-eye look). For solo calls, narrower is usually better.
Aspect ratio
Aspect ratio is the shape of the picture: 16:9 is widescreen (the call standard), 4:3 is squarer (older cameras). The camera test shows which one your webcam is delivering, because a 4:3 image sent to a 16:9 call gets stretched, cropped or pillarboxed.
Facing mode
Facing mode tells you which camera is active: 'user' (front-facing, for selfies and calls) or 'environment' (rear-facing). This mostly matters on phones and tablets, where the rear camera is usually higher quality but points the wrong way for a video call.
How to Improve Your Webcam Quality
The camera test shows what's wrong. These six fixes cover almost every weak result we see.
Add front lighting
A dark or grainy image is almost always a lighting problem. Face a window or put a soft lamp behind your screen so the light falls on your face. Avoid sitting with a bright window behind you, which turns you into a silhouette.
Set the camera at eye level
Raise the laptop or webcam so the lens is level with your eyes. A camera that looks up at you is unflattering; one that looks down flattens you. Eye-level framing looks natural and professional on every call.
Clean the lens
A smudge on a laptop or phone camera softens the whole image and adds haze. Wipe the lens with a microfiber cloth. It sounds obvious, but it's the single fastest way to make a webcam test look sharper.
Simplify your background
A cluttered or moving background distracts and can confuse some call apps' background removal. Use a plain wall, a bookshelf, or your platform's blur or virtual background for a cleaner, more focused shot.
Check browser and OS camera settings
Windows and macOS both let you set a default camera and, on some drivers, exposure and white balance. Make sure the right camera is selected and that any 'auto' exposure isn't set too dark. Then re-run the camera test.
Free up USB and CPU bandwidth
A 4K webcam on a slow USB port or a busy computer drops frames. Plug the webcam directly into a USB 3.0 port, close heavy apps, and the FPS in the camera test should climb back toward 30 or 60.
If the camera test still shows a black screen or "no camera found", walk through the full camera not working guide.
What Your Webcam Test Results Mean
Each number in the camera test points to a likely cause. Here is how to read the most common results.
Low FPS (under 24)
Cause: USB bandwidth, busy CPU, or low light forcing a long exposure.
Fix: Use a USB 3.0 port, close heavy apps, add lighting.
Dark or grainy image
Cause: Not enough light reaching the sensor, or exposure set too low.
Fix: Add front light, raise camera exposure, turn off auto-low-light.
Washed-out / overexposed
Cause: Too much light or auto-exposure overcompensating.
Fix: Reduce light, move away from the window, lower exposure.
Wrong resolution
Cause: Outdated driver or a browser constraint capping the camera.
Fix: Update the webcam driver, try Chrome or Edge, restart.
No device found
Cause: Permission denied or another app (Zoom, Teams, OBS) holds the camera.
Fix: Allow camera permission, quit other camera apps, reload.
Green or purple tint
Cause: Incorrect white balance on the camera sensor.
Fix: Reset white balance in the camera app, or restart the camera.
Webcam Test FAQ
Answers to the most common questions about our camera test.
Is this camera test free?+
Yes. Our webcam test is 100% free, has no ads-walls and never asks you to sign up. Run as many camera tests as you like.
Does the webcam test work on mobile?+
Yes. The camera test runs in any modern mobile browser Chrome, Safari, Edge and Firefox on both Android and iOS.
Is my video uploaded anywhere?+
No. Every frame of the webcam test stays on your device. The page never sends your camera feed to a server.
Which browsers support the camera test?+
Any modern browser that implements getUserMedia: Chrome, Edge, Firefox, Safari, Brave and Opera. Older browsers may not detect your webcam.
Why does the webcam test say my camera is not found?+
Usually one of three reasons: another app is already using the webcam, the browser permission was denied, or the webcam driver isn't installed. Close other apps, allow camera access and try again.
What resolution should my webcam be?+
For video calls 720p (1280x720) is the minimum most platforms accept, but 1080p (1920x1080) is now standard for clear calls and recordings. 4K is only useful for streaming or recording if your connection and platform support it, and most call apps cap you at 1080p anyway.
Why is my webcam FPS lower than 30?+
Low frame rate is usually caused by a slow USB connection (use a USB 3.0 port for 4K webcams), another app holding the camera, low light forcing a long exposure, or an underpowered device. Close other camera apps, add lighting, and plug the webcam directly into the computer, not a hub.
How many megapixels is a good webcam?+
Most 1080p webcams use a 2-megapixel sensor, which is plenty for calls. Higher megapixel counts (4MP, 8MP) help with cropping and detail in good light, but megapixels alone don't mean a better picture. Lens quality, sensor size and lighting matter more than the megapixel number.
Can I test my webcam without an internet connection?+
Almost. Once this page has loaded, the camera test itself runs entirely in your browser using the getUserMedia API, so the video never needs the internet. You only need a connection to open the page the first time; after that the test works offline.
Does the webcam test work on iPhone and Android?+
Yes. On Android use Chrome; on iPhone and iPad use Safari (iOS 14.3+). Both can test the front and rear cameras. Some older Android browsers may not expose the rear camera, in which case try Chrome.
