Test your webcam

See the live picture, the resolution and frame rate your camera really delivers, which sizes it supports, light and colour readings, and save a photo or a short clip.

Your browser asks to use the camera the first time. Nothing is recorded or uploaded.

Camera not working?

Blocked: allow the camera from the icon in the address bar, then reload.
Black picture or “in use”: close video-call apps and other tabs that might hold the camera.
Still nothing: check the system privacy settings and any camera shutter or keyboard camera key.
No camera listed: reconnect it, try another USB port, or restart the browser.
Dark or grainy picture: add light in front of you, not behind you.

Runs in your browser. Nothing is recorded, stored or uploaded unless you download it yourself.

THREE SIMPLE STEPS

How to test your webcam online

Allow the camera

Press Start and allow the camera. Choose another camera from the list if you have more than one.

Check the picture

Look at the preview and the readings: resolution, measured frame rate, exposure and colour balance. Add light in front of you if it says too dark.

Test sizes and save

Run the resolution test to see which sizes your camera delivers, then save a photo or a short clip to compare later.

How to read the results

Resolution and frame rate

The resolution is what the camera is sending now; the measured frame rate counts the frames that actually arrive. Under 24 fps looks choppy, often because the room is dark and the camera lengthens its exposure.

Supported resolutions

Each standard size is requested from the camera. “Supported” means it delivered that size; “Gives …” means it sent another size instead. Some browsers scale the picture, so a size above the sensor’s native size can still appear.

Exposure and colour balance

The histogram shows how much of the picture is dark (left) or bright (right). A pile-up at either edge loses detail. A warm or cool reading means a colour cast from the light; daylight or a neutral lamp fixes most of it.

Webcam test FAQ

How do I test my webcam online?

Press Start and allow the camera. If you see yourself in the preview, the camera works. The readings show its resolution and the frame rate it really delivers; run the resolution test to see which sizes it supports.

Why is my webcam not working?

Most often another app is using it, the browser or system has blocked it, or a privacy shutter or camera key has turned it off. Close video-call apps, allow the camera from the address bar, check your system privacy settings, and reconnect an external camera.

Why does my camera show a lower resolution than advertised?

Browsers start most cameras at a moderate size. Run the resolution test to see the highest size it delivers. Some cameras reach their top resolution only at a lower frame rate, and some USB ports or hubs limit the size.

Why is my frame rate low?

In low light, cameras lengthen each frame’s exposure, which lowers the frame rate. Add light in front of you. A busy computer, a USB hub or a very high resolution can also reduce it.

What does mirror do?

It flips the preview like a mirror, which feels natural. Other people in a call usually see you unmirrored. Saved photos follow the mirror setting.

Why can’t I change focus or brightness?

Only some cameras and browsers let web pages change camera settings. When they do, sliders appear under Camera controls; otherwise use the camera’s own software or your system settings.

Is my video uploaded?

No. The preview, readings and recordings all stay in your browser. A photo or clip is saved only when you download it.
