Webcam and Mic Test: Check Your Camera and Microphone
Test your webcam and microphone before your next Zoom, Teams or Google Meet call. Free, instant, and private: everything runs in your browser.

What good looks like
- Picture: your face is bright and in focus, with light coming from in front of you, not behind. 1280 x 720 (720p) or more.
- Frame rate: 24 to 30 fps keeps movement smooth. A low number usually means not enough light.
- Framing: camera at eye level, your eyes about a third of the way down the frame, a plain wall or bookshelf behind you.
- Sound: the meter sits around the middle while you talk at normal volume. All the way up means too loud or too close; one or two bars means too quiet.
- Playback: your voice is clear with little room echo. If you hear the room, use a headset and turn on noise suppression in your call app.
Camera dark or mic too quiet? See the fixes.
What your result means
- Resolution 1280 x 720 or higher: your camera is fine for Zoom, Teams and Meet. Lower than that: check the camera settings or use a phone or an external webcam. Read the guide
- Frame rate close to 30 fps looks smooth. Under 15 fps usually means poor light or an old laptop camera, so add a lamp in front of you.
- Level meter sitting in the middle while you talk is right. Peaks in the red mean you are too close or the gain is too high.
- Your face dark and the window bright: swap sides so the light faces you. Read the guide
- Playback sounds echoey or far away: use a headset. Read the guide
How it works
The tool uses your browser’s built-in camera and microphone access (getUserMedia). The video preview, level meter and recording stay in your browser’s memory and are deleted when you close the page. Nothing is sent to our server or anyone else. The resolution and frame rate come from the camera track settings your browser reports. If the browser says the camera is in use, another app such as Zoom or Teams is holding it: close that app and try again.
Look and sound good on calls
Face a window or a lamp, never sit with light behind you. Put the camera at eye level on a stand or a stack of books. Use a headset or an external mic rather than the laptop speakers, and turn on noise suppression in your call app. Test your upload speed from your desk: Zoom lists about 3.0 Mbps up for 1080p group calls.
