Webcam and Mic Test
Check Your Camera And Sound

Does the webcam and mic test record me?

Only when you ask. The preview and the meter run live and save nothing. The five-second check records a short clip, but it stays in this tab and is gone when you close it. Your video and sound never reach a server.

Why does the browser ask for permission?

Because a page cannot open your webcam or microphone without your say-so. The browser asks once so you stay in control, and you can allow this test, block it, or change the choice later in the site settings.

My preview is black. What is wrong?

Usually another app holds the webcam. Because only one app gets the webcam at a time, close your meeting app or recorder, then reload this page. In addition, check that a camera cover or privacy shutter is not closed.

The mic meter does not move. How do I fix it?

First, speak at a normal volume and watch the bar. If it stays flat, check a hardware mute switch on the headset or laptop, pick the right microphone from the list, and make sure you allowed mic access.

Can I choose which camera or mic to test?

Yes. Because many devices have more than one camera or microphone, the tool lists them and lets you switch. After you pick one, the preview and the meter follow that device.

Does the test work on a phone?

Yes. Because the page adapts to a small screen, you can test the front or back camera and the mic on a phone or tablet. In practice, this is handy to check a phone before a mobile call.

Is the webcam and mic test free?

Yes, completely. In fact, there is no account, no trial and no watermark. Because the check runs in your browser, there is no server cost, so every part of it stays free.

Which browsers does it support?

It works in any modern browser that can open a camera and a mic, such as Chrome, Edge, Firefox and Safari. However, the page must be secure, so the address needs to start with https for access to work.

Why does it need a secure page?

Because browsers only open the webcam and the mic on a secure address, to protect your privacy. As a result, the test runs over https, and a plain http page will not get access to the devices.

Does the tool upload a photo or clip?

No. Nothing is uploaded or stored on a server. A snapshot saves only to your own downloads, and a test clip lives in the tab until you close it. Then the webcam and mic are released and no copy remains.

Can I test my headset microphone?

Yes. Because the tool lists every microphone it finds, you pick the headset from the list and speak to see the meter move. In practice, this tells you the headset mic is the one in use, not the built-in one.

Will this test my speakers too?

Partly. When you play back the five-second clip, you hear it through your speakers or headphones, so silence there points at the output. However, this tool is built for the webcam and the mic, so a full left and right speaker check is a separate job.

Does a good test mean my call will look fine?

Not always. Because a call also depends on the meeting app and your internet, a clean device test only proves the webcam and mic work. Therefore treat a laggy call as a network question, not a broken camera.

How do I pick the right camera for a call?

Open the webcam list and switch between the options while you watch the preview. Because the picture changes at once, you can see which camera gives the best frame and light, then use that one in your meeting app.

Why is my picture dark or grainy?

It is usually the light, not the webcam. Because a webcam needs light to make a clean image, face a window or a lamp. In addition, a cheap camera looks worse in low light, so more light helps the most.

Can two apps use the webcam at once?

Rarely. Because most systems give the webcam to one app at a time, a second app often gets a black frame. In practice, close the apps you are not using before you test or join a call.

I allowed access by mistake. Can I undo it?

Yes. Because the permission lives in your browser, you can open the site settings for this page and set the webcam and mic back to block or ask. After that, the browser will prompt you again next time.

Does the test drain my battery or slow my device?

Only a little, while it runs. Because a live camera uses some power, close the tab when you finish the check. As a result, the webcam stops and the small drain ends right away.

Can I use it before a Zoom, Meet or Teams call?

Yes. Because it checks the same camera and mic those apps use, a quick test here rules out a hardware problem first. However, pick the matching device in the meeting app too, since each app keeps its own choice.

What resolution is my webcam sending?

The tool shows the size of the picture the webcam streams, such as 1280 by 720. Because that number is the frame the webcam gives the browser, it tells you how sharp your call can look at best.

Does the tool track me or read my video?

No. In fact, your video and sound are never sent anywhere, and no analytics script reads them. The check therefore happens on your device, because nothing about the webcam or the mic leaves the page.
