Webcam Test: Check Your Camera, Resolution and Frame Rate Online

Click start and allow camera access to see your webcam’s live picture. The tool shows the resolution your camera actually delivers and how many frames per second reach the browser. No video or image leaves your device.

How to use this webcam test

  1. Click “Start webcam test” and choose Allow when your browser asks.
  2. Check the picture: focus, colour and brightness. Mirror is on by default, like a video call preview. Turn it off to see what others see.
  3. Read the details: Resolution delivered is what the camera is sending right now; Frame rate measured counts the frames that actually arrive.
  4. Try a higher resolution with Request: 720p / 1080p / 4K. The camera delivers the closest mode it supports.
  5. Take a snapshot to inspect a still frame, then click Stop.

What your result means

  • Low frame rate (under about 15 fps) in a dim room: many webcams lengthen exposure in low light, which lowers the frame rate. Add light facing you and test again.
  • Resolution lower than advertised: some cameras deliver full resolution only to their own software, or only at lower frame rates. USB 2.0 ports and hubs can also limit the modes available.
  • Black image while the camera light is on: a privacy shutter may be closed, or another app has the camera.
  • “No camera was found”: many laptops have a camera key (often an F-key used with Fn) or a side switch that disconnects the camera entirely.

If your webcam isn’t working (Windows 11)

  1. Physical switch or shutter: check for a sliding shutter, a side switch or a camera key on the keyboard.
  2. Windows privacy: Start → Settings → Privacy & security → Camera. Turn on Camera access, Let apps access your camera and Let desktop apps access your camera.
  3. Browser permission: click the icon left of the address bar, set Camera to Allow, then reload.
  4. Close other apps using the camera (Teams, Zoom, the Camera app).
  5. Device Manager: look under Cameras, Imaging devices or Sound, video and game controllers. Right-click the camera and choose Enable device if it’s disabled, Update driver, or Roll back driver after a recent update.
  6. Security software: some antivirus suites have a webcam-protection setting that blocks access.
  7. Troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Camera.

These steps follow Microsoft’s guide, Camera doesn’t work in Windows.

How it works

The tool asks your browser for the camera through the standard getUserMedia API. It reads the resolution the camera delivers from the video stream.

Frame rate is counted from the frames the browser actually receives (requestVideoFrameCallback), so it reflects real delivery, not just the camera’s advertised mode.

Limit: browsers and operating systems may scale or process the video, so results can differ slightly from the manufacturer’s own app.

Privacy

The video is shown only on your screen. Snapshots stay on this page and disappear when you leave. Nothing is uploaded.
