Webcam Test
Check if your webcam is detected and capture a snapshot.
Click "Start Webcam" to begin.
How to Use This Test
Start the Webcam
Click 'Start Webcam' to activate your camera. Grant camera access when your browser prompts you.
Check the Video Feed
Verify the image is clear, well-lit, and properly focused. Check that the correct camera is active.
Capture a Snapshot
Click 'Capture' to take a still photo from the webcam feed. The image will be displayed for review.
Retake if Needed
If the photo didn't turn out well, click 'Retake' to return to the live preview and try again.
What Your Results Mean
Clear Video Feed
Your webcam produces a clear, focused image with accurate colors. The camera hardware is working correctly.
Black or Distorted Feed
The camera feed shows a black screen, severe distortion, or very poor quality. This indicates a camera hardware or permission issue.
Image is Dark or Grainy
Poor lighting can cause dark or noisy images. Try improving your lighting conditions before concluding it's a hardware defect.
Feed is Laggy or Choppy
Low frame rate can be caused by USB bandwidth limitations, high CPU usage, or inadequate lighting forcing slower camera exposure.
Common Problems and Fixes
Camera shows black screen
Check camera permissions in your browser and OS settings. Close other apps that might be using the camera (Zoom, Teams). Ensure the camera lens isn't physically covered or obstructed.
Image quality is poor
Clean the camera lens with a microfiber cloth. Improve your lighting — natural light from a window works best. Check if your browser is applying any filters or effects.
External webcam not detected
Ensure the webcam is connected to a working USB port. Try a different port or cable. Check your OS camera settings to verify the device is recognized.
Snapshot looks different from preview
Some browsers apply different processing to the captured image vs the live preview. This is normal behavior and doesn't indicate a problem.
Frequently Asked Questions
How is this different from the Camera Test?
The Camera Test focuses on verifying camera hardware functionality with pass/fail assessment. The Webcam Test is a simpler utility for quickly checking your webcam feed, capturing a photo, and retaking if needed — useful for profile pictures or quick visual verification.
Why is my webcam image mirrored?
Most front-facing cameras show a mirrored preview by default, like looking in a mirror. This is a standard UX convention that feels more natural. The actual captured image may or may not be mirrored depending on your browser.
Can I save the captured photo?
The test displays the captured image on screen but doesn't provide a download button. To save the image, you can right-click the photo and select 'Save image as...' or take a screenshot of the page.
Does this work with external webcams?
Yes. The browser uses whichever camera is set as the default in your operating system. Connect your USB webcam before starting the test and ensure it's selected as the default camera.
Why is the camera feed laggy?
Lag can be caused by low lighting (camera uses slower exposure), high CPU usage, USB bandwidth limitations (for external webcams), or browser performance. Try closing other tabs and ensuring adequate lighting.
The captured photo looks different from the preview
The preview and capture may use different processing pipelines. Some browsers apply auto-exposure or auto-white-balance adjustments when capturing, which can cause subtle differences in the final image.
