Webcam Test

How to test your webcam

1. Start the camera. Click Start camera (or the big camera button) and choose Allow when your browser asks to use the camera.

   

2. Pick your camera. If you have more than one — built-in, USB, phone or virtual camera — choose it from the menu above the preview.
3. Check the picture. If you can see yourself and the status turns green with Webcam is working, the webcam works. The badges on the picture show the resolution and the frame rate it really delivers.

   

4. Try a higher resolution. Change the resolution or frame rate in Settings to find out what your camera really supports. Camera details shows the size, frame rate and brightness you actually get, and the highest resolution the camera reports.

   

5. Take a photo or record a clip. Capture a still or a short video with sound to check image quality and audio sync, then download it.

   

What the camera details mean

• Resolution is the size of the picture your camera is actually sending, such as 1280 × 720 (HD) or 1920 × 1080 (Full HD). If you ask for a size the camera can’t deliver, it sends the closest one it supports and the page tells you.
• Frame rate is measured live from the video, in frames per second. 30 fps looks smooth on calls; 60 fps is smoother still. Many webcams lower their frame rate in dim light to let in more light per frame.
• Brightness is how bright the picture is overall. Around 30–70% is a well-lit image; “Dim” or “Very dark” means you need more light in front of you.
• Max supported is the highest resolution and frame rate the camera reports to the browser. Chrome and Edge usually show it; some browsers don’t share it.
• Facing tells you whether a phone or tablet camera is the front (selfie) or back camera.

Webcam not working? Fix it step by step

1. Read the message on the test. If the status turns red and says Camera access blocked, your browser or computer is stopping websites from using the camera (steps 2 and 3). If it says Camera is busy, another app is using it (step 4). A black picture usually means a closed privacy shutter (step 5).

   

2. Allow the camera in your browser. Click the icon to the left of the address bar, open Site settings (or Permissions) and set Camera to Allow. Then reload this page and press Start camera again.

   

3. Allow apps to use the camera in your system. Windows 11: Settings › Privacy & security › Camera — turn on Camera access, Let apps access your camera and Let desktop apps access your camera. Windows 10: Settings › Privacy › Camera. Mac: System Settings › Privacy & Security › Camera — turn on your browser, then quit and reopen it. ChromeOS: Settings › Security and privacy › Privacy controls — turn on Camera access.
4. Close apps that may be holding the camera, such as Zoom, Teams, Skype or OBS, or other browser tabs with a video call. Most webcams work with only one app at a time. Then press Start camera again.

   

5. Picture black? Open the privacy shutter. Slide open the shutter or remove the lens cover, and check for a camera on/off key on the keyboard (often F8, F10 or Fn + a function key). The test warns you when the camera is on but sends a black picture.

   

6. On a phone or tablet, allow the camera for your browser. Android: in Chrome, tap the icon next to the address, then Permissions › Camera; also check Settings › Apps › Chrome › Permissions › Camera and the Camera access tile in Quick Settings. iPhone and iPad: open Settings › Apps › Safari › Camera (on older iOS, Settings › Safari › Camera) and choose Ask or Allow.
7. Pick another camera or reconnect it. Choose a different camera from the menu above the preview. For USB webcams, try another port or cable and update the camera driver (Windows: Device Manager › Cameras or Imaging devices), then reload this page.

Picture dark, blurry or choppy?

• Dark or grainy: face a window or a lamp. Light behind you turns your face into a silhouette.
• Low frame rate: more light usually helps, because webcams slow down to expose each frame longer. Plugging a USB webcam into a USB 3 port can also allow higher resolutions at full speed.
• Blurry: clean the lens with a soft cloth and keep it at least an arm’s length from your face so autofocus can lock on.
• Wrong colors: mixed daylight and warm bulbs confuse white balance. Use one kind of light, then check the picture again.
