Webcam test

The test turns on your camera and shows the picture plus the resolution and frame rate it actually delivers to the browser, not the numbers from the box. Then it checks the lighting: is there enough light for people to see you in a call.

Video is processed on this page only and never sent anywhere. A snapshot stays in memory until you press “Download”. The browser asks for camera access after you press “Start test”.

Press “Start test” — your browser will ask for camera access.

What next

How to read the result

  • Resolution — how many pixels the camera really delivers. 1280×720 is fine for calls, 1920×1080 is better for streaming.
  • Frame rate — smoothness. 30 fps is normal; in poor light many cameras drop to 15 on their own.
  • Lighting — average frame brightness. “Too dark” — add light in front of you; “overexposed” — move the window or lamp out of frame.

Frequently asked questions

Is the video recorded or uploaded?
No. The picture is processed in your browser and nothing goes to a server. A snapshot stays in page memory until you download it.
Why is my webcam showing a black screen?
The privacy shutter is closed, another app is using the camera or the browser picked an inactive device. Switch cameras in the list and close calling apps.
Why is the resolution lower than the spec sheet says?
The browser gets the mode the driver and USB port support. Plug the camera into USB 3.0 and make sure it is the selected device.
How do I test the camera on a Mac?
Allow your browser in System Settings → Privacy & Security → Camera, restart the browser and open the test again.
