Webcam / Camera Test
Test your webcam or built-in camera directly in your browser. Preview the live feed, detect resolution and frame rate, and confirm your camera is working correctly — no software required.
Press Start to request camera access. Your video is never recorded or transmitted.
What is a Webcam Test?
A webcam test checks whether your built-in or external camera is functioning correctly by displaying a live preview and detecting key technical specifications — resolution, frame rate, and device name. This is useful for troubleshooting camera issues before video calls, verifying that a new or used webcam is working as advertised, confirming the correct camera is selected when multiple devices are connected, and diagnosing image quality problems. Our browser-based test requires no software installation and processes all video locally — nothing is recorded or transmitted.
What This Test Checks
Live Video Preview
Shows your camera feed in real-time so you can immediately see if the image is clear, correctly oriented, and free of artifacts. This is the most direct way to confirm your camera is functioning.
Resolution Detection
Displays the actual resolution your camera is delivering (e.g., 1920×1080, 1280×720). This may differ from the camera's advertised maximum if OS settings or USB bandwidth are limiting it.
Frame Rate (FPS) Measurement
Shows both the reported FPS from the camera driver and the live-measured FPS from browser frame timing. Most webcams target 30 fps; high-end models support 60 fps or higher.
Device Name
Identifies which camera device is active, helping you confirm the correct camera is selected when multiple cameras are connected (e.g., laptop built-in vs. USB webcam).
Multi-Camera Support
If your device has multiple cameras, a dropdown appears to switch between them. Useful for laptops with front and rear cameras, or desktop setups with multiple USB webcams.
Megapixel Calculation
Calculates megapixels from the detected resolution, so you can compare against the manufacturer's spec and verify the camera is operating at its full resolution capability.
Camera Troubleshooting Guide
Camera Permission Denied
Click the camera/lock icon in the browser address bar and set camera permission to Allow. On Chrome: click the icon → Site Settings → Camera → Allow. Refresh the page and try again. If the option is missing, check your OS privacy settings — on Windows 11: Settings → Privacy & Security → Camera → enable browser access.
No Camera Found
Verify the camera is physically connected. For USB webcams, try a different USB port. Open Device Manager (Windows) and look for camera errors (yellow exclamation marks). Check that no other application has exclusive camera access — video conferencing apps often hold the camera lock even when not in active calls. Close Teams, Zoom, or OBS, then test again.
Low Resolution or Poor Image Quality
Low resolution usually means either the camera hardware is limited or a USB bandwidth issue. High-resolution webcams (1080p+) require USB 3.0 bandwidth — try connecting directly to a USB 3.0 port on your computer rather than through a hub. Clean the lens with a dry microfiber cloth. Ensure adequate, even lighting — webcam image quality degrades significantly in low light.
Low Frame Rate (Under 30 FPS)
Low FPS usually indicates insufficient lighting (auto-exposure increases exposure time to compensate for dim light, reducing FPS), high CPU load interfering with frame processing, or driver issues. Improve your lighting setup and close background applications. Check the manufacturer's camera control software for manual exposure settings.

About This Test
How it works: This test uses the browser's MediaDevices.getUserMedia() API to access your camera stream. Resolution and FPS are detected from the MediaStreamTrack settings object. Live FPS is measured independently using requestAnimationFrame timestamps to verify the actual delivery rate matches the reported rate.
Privacy: Your camera stream is processed entirely in your browser. No video, images, or frames are transmitted to any server. The camera stream is terminated immediately when you stop the test or close the tab. We do not access the camera unless you explicitly click Start Camera.
Browser compatibility: This test works in Chrome, Firefox, Edge, and Safari (iOS 11+). For best results, use Chrome or Edge on desktop. Some mobile browsers may restrict camera access or limit available resolutions.
