How to use Mic, Webcam & Keyboard Tester

  1. Pick a test: Microphone, Webcam, Speakers, Keyboard or Screen.
  2. Press Start and allow access when the browser asks (microphone and camera only). Speak, look at the picture, play the left and right tones, press every key, or step through the full-screen colours.
  3. Check the result: the level bar and playback, resolution and frame rate, green keys and how many keys register at once, or any pixels that stay wrong. Stop when you are done.

What are the limits of Mic, Webcam & Keyboard Tester?

Everything runs in your browser tab and stops when you leave; the 5-second test recording is never saved or uploaded. Browsers report camera resolution and frame rate approximately. Laptop keyboards may not send some keys (such as Fn), and phones show their own on-screen keyboard.
