One check for both camera and microphone

Joining a video call and finding out your camera is black or your mic is silent is stressful, and it’s avoidable. This page opens your webcam and your microphone together, shows a live preview beside your audio level, and lets you record a quick sound check.

The preview is mirrored, the way most meeting apps show you to yourself. Other people on a call see you the right way round. The video is shown on your screen only. It isn’t recorded, uploaded or stored.

How to test your webcam and mic together

  1. Press “Test my camera and mic”

    Your browser asks for both the camera and the microphone. Allow both. Some browsers show one prompt, others ask twice.

  2. Check your picture

    Look at the preview for framing, focus and light. Your eyes should sit about a third of the way down the frame, with light on your face, not behind you.

  3. Check your sound

    Speak normally and watch the level meter beside the video. Then record 5 seconds and play it back to hear how you come across.

  4. Switch devices if you need to

    If you have more than one camera or microphone, menus appear so you can pick the ones you plan to use on the call.

Look better on camera in a minute

  • Face the light. A window or lamp in front of you beats any camera upgrade. A bright window behind you turns you into a silhouette.
  • Raise the camera to eye level. A laptop on a stack of books is enough. Looking down into a camera is rarely flattering.
  • Clean the lens. A fingerprint on a laptop or phone camera makes the whole image hazy.
  • Check what’s behind you. The preview shows exactly what everyone else will see.

If the camera preview stays black

First look for a physical cover. Many laptops have a sliding shutter over the lens or a camera key on the keyboard, and an external webcam may have a lens cap.

Next, close other apps that might be using the camera, such as Zoom, Teams, FaceTime or a camera app. On Windows in particular, only one app can use a webcam at a time.

Finally, check permissions. Your browser needs camera access for this site, and your operating system needs to allow your browser to use the camera at all. If the mic part of the test works and the camera doesn’t, permissions are the usual reason.

Questions and answers

Is my video recorded or uploaded?

No. The camera preview is drawn on your own screen and goes nowhere else. Nothing is recorded, saved or sent to a server. The camera turns off when you press Stop or leave the page.

Why is my camera preview flipped?

The preview is mirrored so that moving left looks like moving left, which feels natural. Meeting apps do the same thing. People on the other end of a call see you unmirrored.

My mic works but the camera doesn’t. What should I check?

Check for a lens cover or camera-off key, close other apps that may be holding the camera, and make sure both your browser and your operating system allow camera access. The mic test keeps working even when the camera can’t start.

Can I test an external webcam?

Yes. Plug it in, start the test, and choose it from the Camera menu. Many webcams also have their own microphone, which will show up in the Microphone menu.

What resolution does the test use?

The test asks your camera for a 720p picture and shows the resolution your browser actually delivered in the panel under the tool. Your meeting app may use a different resolution depending on your connection.

Does this work on phones and tablets?

Yes. On a phone the test uses the front camera and the built-in microphone, or your headset’s mic if one is connected.
