Mic & Camera Test

Make sure your microphone and webcam actually work before you join a meeting or hit record — right in your browser. You see your camera and watch your mic level move, and nothing is ever uploaded.

Start the test, then speak

Everything runs locally — nothing is recorded or uploaded.

How to use it

  1. 1Click Start test and allow your browser to use the camera and microphone.
  2. 2Check the camera preview looks right, then speak — the mic level bar should move.
  3. 3If the bar moves and you see yourself, you are good to go. Click Stop when done.

The worst time to discover your microphone is muted or your webcam points at the ceiling is thirty seconds into a meeting. A quick test beforehand removes that risk: confirm the right devices are active, that the camera shows you, and that the mic actually picks up your voice.

This free tool asks your browser for camera and microphone access, shows a live camera preview, and displays a level meter that moves when you speak. It is the fastest way to check you are ready before a Zoom, Google Meet, or Teams call, a webinar, or a recording. Everything runs locally in your browser — nothing is recorded, saved, or uploaded.

A good mic and camera are half the battle in any call. The other half is your screen share: if you are presenting slides, a design, or a demo, the people watching still need to follow your cursor and your clicks — which is exactly what a live on-screen overlay is for.

FAQ

Is this mic and camera test free?
Yes, completely free with no sign-up. It runs in your browser and nothing is recorded or uploaded.
Does it record or save anything?
No. It only shows a live preview and a mic level meter. Nothing is captured or sent anywhere.
Why can I see myself but the mic bar does not move?
Your browser may be using a different microphone, or the device is muted. Check your system sound input and that mic access was allowed.
Will this help my screen sharing too?
This tests your devices. To make your actual screen share easy to follow, use Limelight — it adds a cursor spotlight, on-screen keystrokes, and drawing over any app.
