How to Use
Allow Camera Access
Click 'Start Camera Test' and allow the browser to access your webcam. For privacy, your video never leaves your device.
Check Video Quality
Once the camera starts, you'll see live video with real-time stats including resolution, FPS, and aspect ratio.
Switch Cameras
If you have multiple cameras (front/rear on mobile, or external webcams), use the dropdown to switch between them.
Test Microphone
Enable the microphone test to check if your mic is working. The audio level bar shows real-time input volume.
Features
Resolution Detection
Automatically detects and displays your camera's actual output resolution. Test if your 1080p or 4K webcam is performing as expected.
Real-time FPS Monitor
Shows live frame rate to verify smooth video capture. Essential for streaming, video calls, and recording quality checks.
Multi-Camera Support
Switch between built-in, external USB, and virtual cameras. Perfect for testing different webcams or front/rear cameras on mobile.
Microphone Check
Visual audio level meter confirms your microphone is working and picking up sound correctly. Great for pre-meeting checks.
Mirror Mode
Flip the video horizontally to see yourself as others see you, or as you see yourself in a mirror. Toggle instantly.
Snapshot Capture
Take instant photos from your webcam feed. Images are saved locally to your device - nothing is uploaded anywhere.
Common Use Cases
Pre-Meeting Check
Test your webcam and microphone before Zoom, Teams, or Google Meet calls to avoid technical issues during important meetings.
Webcam Purchase Verification
Verify that a new webcam actually delivers its advertised resolution and frame rate before you commit to keeping it.
Streaming Setup
Streamers can quickly check camera quality, test different resolution settings, and ensure proper frame rates for smooth broadcasts.
Troubleshooting
Diagnose webcam problems by checking if the browser can access the camera, what resolution it outputs, and if the mic works.
Privacy & Security
This tool is 100% client-side. Your video stream is processed entirely in your browser using standard Web APIs. No video data, images, or audio is ever transmitted to any server. You can verify this by using the tool while offline or by monitoring network traffic.
Tips
- For best results, ensure good lighting. Low light causes lower frame rates and poorer image quality.
- Close other applications using the camera (Zoom, Teams, OBS) before testing to avoid conflicts.
- If the camera isn't detected, try refreshing the page or checking browser permissions in settings.
- External USB webcams often provide better quality than built-in laptop cameras for professional use.
- Use Chrome or Edge for the best compatibility with camera APIs and features.
