What the webcam test checks
A quick camera check saves you from the classic “can you see me?” at the start of a meeting, an online exam or a job interview. This test opens your webcam directly in the browser, the same way Zoom, Google Meet, Microsoft Teams and other web apps do, so if it works here it will work there too.
Resolution and megapixels
The resolution shown is what the camera is really sending, not what the box promises. Most laptop cameras deliver 1280 × 720 (HD) and better external webcams 1920 × 1080 (Full HD) or even 4K. Browsers often start a camera at a low 640 × 480, so this test asks for HD automatically. Use the Resolution menu to try other sizes, and look at Maximum resolution to see the largest picture the camera reports.
Frame rate
The frame rate is measured from the frames that actually arrive, so it shows the smoothness you will really get. 30 fps is standard for video calls; 60 fps looks noticeably smoother. Many webcams lower the frame rate in dim light to collect more light, so if you see 15 fps, try turning on a lamp.
Lighting
The lighting meter checks how bright the picture is. A dark picture looks grainy and blurry, especially on small laptop cameras. Face a window or lamp rather than sitting with a light behind you. If the picture is completely black, the camera is working but something is covering it: many laptops have a small privacy shutter or a camera key that turns it off.
When the camera does not start
If access was blocked, click the camera or lock icon next to the address and allow the camera. On Windows, open Settings › Privacy & security › Camera and make sure camera access and desktop apps are allowed; on a Mac, check System Settings › Privacy & Security › Camera for your browser. A “camera in use” message means another app, such as Zoom or Teams, still holds the camera: close it and try again.
Private by design
The video is shown only on this page and is never recorded, saved or uploaded. Photos you take stay in your browser until you download them. The camera turns off as soon as you press Stop or close the page.
Frequently asked questions
Why does my webcam not work?
The most common reasons are a blocked permission, another app using the camera, or a privacy shutter. Allow the camera in the address bar, close apps like Zoom or Teams, check the camera privacy settings in Windows or macOS and make sure nothing covers the lens.
How do I allow camera access in my browser?
Click the camera or lock icon at the left or right of the address bar, set Camera to Allow and reload or press Try again. In Chrome you can also open Settings › Privacy and security › Site settings › Camera.
What resolution is my webcam?
Start the test and read the Resolution value: it is the size of the picture the camera is sending right now. Maximum resolution shows the largest size the camera reports. Choose a higher option in the Resolution menu to try it.
Why is my webcam picture dark or grainy?
Small webcam sensors need a lot of light. Face a window or a lamp, avoid strong light behind you and clean the lens. In dim light many cameras also lower their frame rate, which can make video look choppy.
Is my video recorded or uploaded?
No. The video is processed only in your browser and is never saved or sent to a server. Photos you take stay on your device until you download them.
