Why Test Your Webcam?
Testing your webcam before important video calls or recordings helps ensure everything works properly. Common issues like incorrect resolution, poor lighting, or microphone problems can be identified and fixed before they cause problems during your actual meeting or stream.
Who Should Use This Tool?
This webcam tester is useful for:
- Remote workers preparing for video conferences
- Content creators setting up streaming equipment
- Anyone buying or testing a new webcam
- Users troubleshooting camera issues on their computer
How to Use Webcam Tester
Testing your webcam is quick and straightforward. Follow these steps to check your camera and microphone.
Enable Camera Access
Click the "Enable Camera" button to start. Your browser will ask for permission to access your camera. Click "Allow" to proceed. If you accidentally deny permission, you'll need to enable it in your browser settings.
Check Video Preview
Once permission is granted, you'll see a live video preview from your webcam. The overlay badges show your current FPS (frames per second) and video resolution. These metrics help you understand your camera's performance.
Adjust Settings
Use the dropdown menus to customize your test:
- Camera: Select from multiple cameras if you have more than one connected
- Resolution: Choose from 480p, 720p, 1080p, 1440p, or 4K (if supported)
- Microphone: Select a microphone to test audio input levels
Use Mirror and Flip Controls
The Mirror button flips your video horizontally, making it appear like looking in a mirror. This is the default setting for most video calls. The Flip button inverts the video vertically, which is useful for specific camera mounting positions.
Capture Test Photos
Click the red capture button or press the Spacebar to take a photo. Captured images appear in the gallery below where you can preview them in full size or download them to your device.
Test Your Microphone
Select a microphone from the dropdown to enable audio level monitoring. The meter shows real-time audio levels in decibels (dB). Speak into your microphone to see the levels respond, helping you verify that audio input is working correctly.
Features
Webcam Tester provides comprehensive tools to test and verify your camera and microphone setup.
Live Video Preview
View your webcam feed in real-time with a high-quality preview window. The video maintains proper aspect ratio (16:9 or 4:3 depending on your camera) and displays smoothly without lag.
Multiple Camera Support
If you have multiple cameras connected (built-in laptop camera, external USB webcam, virtual camera), you can easily switch between them using the camera dropdown menu.
Resolution Selection
Test your camera at different resolutions including 480p, 720p, 1080p, 1440p, and 4K. The tool will automatically fall back to the highest supported resolution if your camera doesn't support the selected option.
Real-Time Statistics
Monitor important camera metrics displayed as overlay badges:
- FPS counter: Shows frames per second, indicating video smoothness
- Resolution display: Shows actual output resolution from your camera
- Aspect ratio: Displays the video aspect ratio (16:9, 4:3, etc.)
Mirror and Flip Controls
Adjust video orientation with dedicated buttons. Mirror mode flips the image horizontally (default on), while Flip mode inverts it vertically. Both can be combined for full rotation.
Photo Capture
Take snapshots from your webcam feed with a single click or keyboard shortcut. Photos are saved with your current mirror/flip settings applied. Captured images can be previewed in a modal or downloaded as PNG files.
Lighting Assessment
The built-in lighting indicator analyzes your video feed and provides feedback on your lighting conditions. It shows whether your lighting is too low, good, or too bright, helping you optimize your setup for better video quality.
Audio Level Meter
Test your microphone with a professional-style audio level meter. The meter displays:
- Real-time levels: Visual bar showing current audio input
- dB measurement: Numeric decibel reading from -60 to 0 dB
- Peak indicator: Marks the highest recent audio level
Privacy Protection
All video and audio processing happens entirely in your browser. No data is transmitted to any server, ensuring your privacy is fully protected during testing.
Frequently Asked Questions
Why is my webcam not showing up?
If your webcam doesn't appear, first check that it's properly connected to your computer. Make sure you've granted camera permission in your browser when prompted. If you denied permission accidentally, click the camera icon in your browser's address bar to change the setting. Also verify that no other application is currently using the camera.
Why is the video quality poor?
Poor video quality can result from several factors. Try selecting a higher resolution from the dropdown menu. Check if your lighting is adequate using the lighting indicator. Ensure your camera lens is clean and not obstructed. If using an older webcam, the hardware itself may have limited quality capabilities.
Can I test my webcam on mobile devices?
Yes, Webcam Tester works on mobile devices with cameras. On smartphones and tablets, it will access your device's front or rear camera. The interface is responsive and adapts to smaller screens while maintaining full functionality.
Is my video recorded or stored anywhere?
No. All video and audio processing happens entirely within your browser. Nothing is transmitted to any server. When you capture photos, they are stored temporarily in your browser session and will be cleared when you close the page or click "Clear All".
Why doesn't my selected resolution work?
Webcams have maximum supported resolutions. If you select 4K but your camera only supports 1080p, the tool will automatically use the highest resolution your camera can provide. The actual output resolution is displayed in the overlay badge.
How do I test my microphone?
Select your microphone from the Microphone dropdown menu. If this is your first time, click "Click to enable microphone" and allow browser permission. Once enabled, speak into your microphone and watch the audio level meter respond to your voice.
What does the lighting indicator mean?
The lighting indicator analyzes the brightness of your video feed. Low (yellow) means you need more light. Good (green) indicates optimal lighting. Bright (blue) suggests there may be too much light or glare in your setup.
Can I use this to test virtual cameras?
Yes, virtual cameras (like OBS Virtual Camera, ManyCam, or similar software) will appear in the camera dropdown alongside physical cameras. Select the virtual camera to test its output.
Why is my FPS low?
Low FPS can be caused by high CPU usage from other applications, USB bandwidth limitations when using multiple devices, or camera hardware limitations. Try closing other applications, using a different USB port, or selecting a lower resolution to improve FPS.
How do I fix a mirrored or inverted image?
Use the Mirror and Flip buttons below the video preview. Mirror flips the image horizontally (enabled by default), while Flip inverts it vertically. Toggle these buttons until your video appears correctly oriented.
