How to test your webcam online

Check the correct camera, preview quality, lighting, focus, frame rate, and supported resolutions before a video call.

Your raw webcam video stays on this device. MicTestLab analyzes preview frames in your browser.

Prepare your webcam

  1. Connect the camera and remove any privacy cover before you open the test.
  2. Close other apps that may be using the camera.
  3. Face a soft light and place the camera near eye level.

Run the webcam test

  1. Open the Webcam test and select the camera that you want to check.
  2. Select Start Camera Test, allow camera access, and wait for the preview to settle.
  3. Review the preview, active resolution, frame rate, lighting, sharpness, and optional resolution scan.

Common webcam problems

The camera does not start

Check browser and operating system permissions, close other camera apps, and confirm that the privacy cover is open.

The image is dark or washed out

Add soft light in front of you and avoid a bright window or lamp directly behind you.

The image is blurry or unstable

Clean the lens, hold the camera steady, improve the light, and check whether autofocus has settled.

Understand the results

Resolution

Active resolution is the size of the current browser video stream. The scan checks which common sizes the camera accepts.

Frame rate

FPS shows how many video frames arrive each second. Low or unstable FPS can follow poor light, camera limits, USB bandwidth limits, or heavy system load.

Lighting and sharpness

These are practical browser estimates from preview frames. They are not calibrated camera certification.
