How to use the Webcam Test
- Click Start webcam test and allow camera access.
- Check the preview, then read the real resolution and the measured frame rate below it.
- Switch cameras or request a higher resolution, and save a snapshot if you like.
What the numbers mean
Resolution is what the camera actually delivers, not what the box says: many “1080p” webcams fall back to 720p in low light or over USB 2.0. Frame rate is measured from the frames your browser receives — 30 fps looks smooth on calls, 60 fps suits streaming. If it drops to 15 fps, the room is usually too dark and the camera lengthens its exposure.
Camera not working? Check these
- Permission — allow camera access with the icon in the address bar, then start again.
- In use elsewhere — on Windows only one app can use a camera at a time; close Teams, Zoom or the Camera app.
- Privacy switch — many laptops have a physical shutter or a function key that disables the camera.
- System privacy settings — Windows: Settings → Privacy & security → Camera. macOS: System Settings → Privacy & Security → Camera, and allow your browser.
Tips for a better picture
Face a window or a soft light instead of sitting with it behind you, put the camera at eye level, and clean the lens. More light lets the camera keep its full frame rate and lowers noise.
Private: nothing leaves your device
The test runs entirely in your browser. The camera image is processed locally and is never uploaded, recorded on a server or shared. When you leave the page or press Stop, access ends — your browser shows when the camera is in use.

Tools that pair well with the Webcam Test
- Mic Test — Check that your microphone works and sounds right before a call, stream or recording — see the live level, watch the waveform and play back a short test recording.
- QR Code Scanner — Point your camera at a QR code, or drop an image or screenshot that contains one.
- Dead Pixel Test — Fill your screen with solid colors, gradients and test patterns to spot dead or stuck pixels, backlight bleed and banding — on a new monitor, laptop, TV or phone.
- Keyboard Tester — Press every key and watch it light up on the on-screen keyboard — find dead, stuck or repeating keys, see the key and code for each press, and check how many keys register at once.
