How this webcam test works
Click Start camera test and allow access when your browser asks. The live preview appears right away and shows exactly what your camera sees. Under the preview you get the real resolution the camera is delivering, the frame rate, the device name and whether it is a front or rear camera.
Everything happens inside your browser using the standard getUserMedia API. The video never leaves your computer or phone. We do not record, store or transmit anything, and the page works offline once it has loaded.
What to check
- Picture quality. A sharp, well-lit image at 720p or 1080p is what most video call apps expect. A blurry picture usually means a dirty lens or a plastic protection film left on the camera.
- Resolution. Most built-in laptop cameras deliver 1280×720. External webcams usually offer 1920×1080 or more. If you see 640×480, another app may be holding the camera at a low setting, or a USB 2.0 hub is limiting bandwidth.
- Frame rate. 30 fps is normal. If it drops under 15 fps, the room is probably too dark and the camera is lengthening its exposure time. Add light or lower the resolution in your call app.
- Device list. If you have more than one camera, pick each one from the drop-down to make sure the right camera is selected in Zoom, Teams or Google Meet.
Camera not working? Try these fixes
- Allow permission. Click the lock or camera icon in the address bar, set Camera to Allow and reload the page.
- Close other apps. Only one program can use most webcams at a time. Quit Zoom, Teams, Skype, OBS or any other app that may be holding the camera.
- Check the privacy shutter and switch. Many laptops have a physical slider over the lens or a keyboard shortcut (often Fn + F6 or similar) that disables the camera.
- Operating system privacy settings. On Windows go to Settings → Privacy & security → Camera and allow desktop apps and your browser. On macOS go to System Settings → Privacy & Security → Camera and tick your browser. On Android and iOS check the browser's permissions in the system settings.
- Reconnect or update. For an external webcam, unplug it, plug it into a different USB port directly on the computer, and check for a driver update from the manufacturer.
- Try another browser. If the camera works in a different browser, reset the site permissions in the original one.
Why test your webcam before a call?
Joining a meeting with a black square or a frozen picture wastes everyone's first minutes. A ten-second check here tells you whether the camera, the drivers and the permissions are all in order, and lets you adjust framing and lighting before anyone sees you.
Frequently asked questions
Is my camera feed uploaded anywhere?
No. The video is processed entirely inside your browser. Nothing is sent to our servers, and we cannot see your camera.
Why does the preview look mirrored?
We flip the preview horizontally so it behaves like a mirror, which feels natural. People on a video call see you the right way round. You can switch mirroring off with the Mirror button.
Why is my webcam showing a black screen?
Most often another app is using the camera, a privacy shutter is closed, or the browser does not have permission. Close other apps, open the shutter, and allow camera access in the address bar.
Does this work on my phone?
Yes. On Android and iPhone you can test both the front and the rear camera. Pick the camera from the drop-down list.
What resolution should my webcam have?
720p (1280×720) is fine for most calls. 1080p (1920×1080) looks sharper on larger screens. Streaming and recording benefit from 1080p or 4K.
How do I test my webcam in Zoom, Teams or Google Meet?
Run this test first to confirm the camera works in the browser, then open the video settings in your meeting app and select the same camera. If it works here but not in the app, check that the app has camera permission in your operating system privacy settings and that no other program is using the camera.
How do I test an external webcam?
Plug it in before opening this page, allow camera access and choose the webcam from the camera list. If it does not appear, try another USB port without a hub and check that the operating system lists it as a camera.
