Webcam Test
Check your camera with a live preview before your next call.
Permission is only requested when you start the test. Nothing is recorded or uploaded.
Your test runs locally in your browser. No device data is uploaded.
How to use the webcam test
Press Start webcam test and allow camera access. A live preview appears; press Stop test to release the camera.
What this test checks
The preview comes straight from your camera to the page. No frames are recorded, stored or uploaded.
If the preview stays black, another application may already be using the camera, or a privacy shutter is closed.
Image quality here reflects what video call apps will show, including exposure and framing.
Common webcam problems
A blocked permission, a physical shutter or another app holding the camera are the three most common causes of a black preview.
Frequently asked questions
- Is any video recorded or uploaded?
- No. The preview is rendered locally in your browser and discarded. Nothing is recorded, stored or sent anywhere, and stopping the test releases the camera immediately.
- The preview is black. What is wrong?
- Most often a privacy shutter or a piece of tape over the lens, or another application still holding the camera. Close video calls and anything else that might be using it, check the physical shutter, then reload and try again.
- The browser will not ask for permission. How do I reset it?
- The site has probably been blocked already. Open the site settings from the padlock icon in the address bar, set camera access back to ask or allow, then reload the page.
- Can I test a specific camera if I have more than one?
- Yes — choose it from the device list. Laptops with both a built-in camera and an external one show both once you have granted camera permission.
- The image is dark or grainy. Is the camera faulty?
- Usually not. Webcams have small sensors and lean heavily on light, so a backlit window behind you will silhouette your face and a dim room will produce visible noise. Put a light source in front of you before concluding the camera is at fault.
