Webcam Test
Start the test to see your live picture, resolution and frame rate in seconds. Free and private: the video never leaves your device.
Camera not working? Find the fix for your device or app
If the test above shows no picture, the cause is usually your device: a privacy setting, a missing driver or another app that is already using the camera. Pick your device below. If the camera works here but not in one app, pick that app: the fix is in its camera settings or permissions.
Need a mirror before a call? Open the online mirror: full screen, zoom and brightness, nothing is recorded.
Check all your audio connections before going live by launching the real-time mic status checker and troubleshooter, and ensure even sound output with the online loudspeaker test for instant results.
Check your camera before the call starts
Press the button above and allow camera access. You see a live preview within a second, plus the resolution, frame rate and aspect ratio your camera actually delivers. If you have several cameras, switch between them from the menu under the video. The test runs entirely in your browser: the video is never uploaded or recorded.
How to test your webcam
The whole test takes about ten seconds.
Start the test
Press the camera button at the top of the page.
Allow camera access
Your browser asks for permission to use the camera. Choose Allow. If you blocked it earlier, change it from the icon at the left of the address bar and reload the page.
Look at the live preview
If you see yourself, the camera, its driver and your browser all work. A black picture usually means the lens is covered, a privacy shutter is closed or another app is using the camera.
Read the camera details
Under the video you see the resolution (for example 1280 × 720 or 1920 × 1080), the frame rate and the aspect ratio the camera is sending right now.
Try the other cameras and tools
Pick another camera from the menu, mirror the image, open it full screen, or take a picture to check sharpness and colors.
What the results mean
Resolution
1280 × 720 is HD (720p), 1920 × 1080 is Full HD (1080p) and 3840 × 2160 is 4K. Video-call apps often send less than your camera can deliver to save bandwidth, so a lower picture quality in a call does not always mean a weak camera.
Frame rate
Most webcams deliver 30 frames per second. Many lower it automatically in dim light, which makes motion look choppy; more light in front of you usually brings it back up.
Aspect ratio
1.78 means a 16:9 widescreen picture and 1.33 a 4:3 picture. Apps may crop the image to their own format.
If the test shows an error
Access to the webcam has been denied
The browser or the operating system blocks the camera. Allow it for this site in the browser, then check the camera privacy settings of Windows, macOS, iOS or Android (see the device guides on this page).
No camera found
The device does not report any camera. Check the privacy shutter or camera key on laptops, reconnect an external webcam directly to the computer, and check the driver.
The camera starts but stays black or the test fails
Another app is probably holding the camera. Close video-call apps and other browser tabs that use the camera, then press the button again.
It works here but not in Zoom, Teams or WhatsApp
Your camera is fine; that app needs camera permission or has another camera selected. Open the guide for that app from the list on this page.
Frequently Asked Questions
Why is my webcam not working?
The most common causes are a missing permission (browser or system privacy settings), another app already using the camera, a closed privacy shutter or a camera key that turned it off, and an outdated or disabled driver on Windows. The test on this page tells you which one applies.
Why does my camera show a black screen?
Usually the lens is covered, the privacy shutter is closed, or another app is holding the camera. On laptops, also check for a keyboard key with a camera icon that turns the camera off.
How do I allow camera access in my browser?
Click the icon at the left of the address bar, set Camera to Allow and reload the page. In Safari on Mac, use Safari › Settings for this website. On iPhone and iPad, check Settings › Apps › Safari › Camera.
My camera works here but not in Zoom or Teams. Why?
Then the hardware and driver are fine. The app either has no camera permission in your system settings or uses a different camera. The app guides on this page show where to change both.
What resolution is my webcam?
Start the test: the resolution the camera currently sends is shown under the video. Most laptop cameras deliver 720p or 1080p.
Is this webcam test private?
Yes. The video is shown only on your screen and is processed in your browser. It is not uploaded, recorded or shared. A picture you take is saved directly to your device.
