Check your camera works, with its real resolution and frame rate, before a video call
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.A webcam test starts the camera in the browser and shows the live picture with what it really sends, such as 1280 × 720 at 30 frames per second. If no picture appears, the page names the cause, such as a refused permission or another app using the camera.
Press Start camera and allow the camera when the browser asks.
Check the live picture, then read the Resolution and Frame rate the camera is actually sending.
Choose another camera from the list if you have more than one, and turn Mirror on or off.
Press Take a snapshot to save a still to your device, and Stop camera when you are done.
Before an interview or a video call it helps to know three things: the camera works, the picture is the quality you expect, and nothing else is holding the camera. This page starts the camera only when you press Start, shows the live picture, and reads what the camera is actually delivering.
What it shows. The resolution the camera is sending, with its common name (720p, 1080p, 4K), the megapixels and the aspect ratio, and two frame rates: the one the camera reports and one measured from the frames the page receives. A laptop camera advertised as 1080p often sends 720p in a browser, and a measured rate well below 30 frames per second usually means poor lighting, a busy computer or a USB port that is too slow.
More than one camera. After permission is given, the list shows every camera the browser can see, such as a laptop's built-in camera and a USB webcam, or the front and back cameras of a phone. Mirror flips the preview the way most call apps show your own picture; the other people on a call see it the right way round.
When it does not work. The page explains the browser's error in plain words. The most common causes are a refused permission, another app such as Zoom, Teams or the Camera app already using the camera, a privacy shutter or a camera key switched off, and in-app browsers, such as those inside Instagram or Facebook, that cannot use the camera at all.
Privacy. Nothing is recorded or uploaded. The picture goes from the camera to this page and nowhere else. A snapshot is saved only to your own device when you press the button. Stop camera, or leaving the page, switches the camera off, and the camera light goes out.
It does not test the microphone; the speaker and microphone test does that.
Press Start camera on this page and allow the camera when the browser asks. The live picture appears with the resolution and frame rate the camera is sending. If it fails, the page names the cause, such as a refused permission or another app using the camera.
The usual causes are a permission refused for this site, another app such as Zoom or Teams already using the camera, a privacy shutter or camera key switched off, or a browser inside an app that cannot use cameras. Close other camera apps and allow the camera in the address bar.
The page reads the resolution from the camera stream itself, so it shows what a call app would receive, such as 1280 × 720. Many laptop cameras sold as 1080p send 720p to browsers, and poor light can lower the frame rate below 30 frames per second.
No. The picture goes from the camera to this page only, and nothing is stored or sent. A snapshot is saved to your own device only when you press the button, and Stop camera or leaving the page switches the camera off completely.
Preview pictures are usually mirrored so moving your hand right moves it right on screen, as in a mirror. Other people on a call see the picture the correct way round. Turn Mirror off to see it as others will.
Yes. After the first permission, the camera list shows every camera the browser can use, including the front and back cameras on most phones. Pick one from the list and the picture and readings switch to it.
