How it works and what the result means
The displayed width, height and frame rate come from the negotiated camera track settings. The preview stays on your device and is not uploaded.
Reading the result
The shown settings describe the delivered camera track. They may differ from the sensor maximum because the browser negotiates a mode.
What to check next
Check the selected camera, privacy shutter and system permission. Another application may already hold the camera.
Camera access needs HTTPS or localhost. If permission is denied, use the browser site settings to allow it and retry.
Frequently asked questions
Is the preview uploaded or streamed publicly?
No. This tool displays the local MediaStream on your device. It does not publish or upload the camera feed.
How do I start the Webcam Test?
Start the camera, approve the browser permission and inspect the local video preview. Stop the camera when done.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
