How it works
This tool uses navigator.mediaDevices.getUserMedia() to request access to your webcam. The live video feed is displayed using an HTML5 <video> element. Resolution is read from the video track's videoWidth and videoHeight properties. FPS is measured by counting frames via requestAnimationFrame. All processing happens locally in your browser — no video data is sent anywhere.
How to Test Your Webcam
Click the button above to start your camera preview. Once active, you'll see a live video feed along with your camera's resolution, frame rate, and device name. This tells you everything you need to know: is the camera working, is the image clear, and is the resolution high enough for video calls?
For video calls, 720p (1280×720) is the sweet spot — it looks good without using excessive bandwidth. Most modern laptops have 720p or 1080p built-in cameras. If your camera shows a lower resolution, check your browser settings or try a different browser. External USB webcams often support higher resolutions and better frame rates than built-in laptop cameras.
Common Webcam Problems and Fixes
- "Camera not found" — Make sure your camera isn't being used by another app (Zoom, Teams, FaceTime). Only one application can access the camera at a time. Close other video apps and try again. On macOS, check System Settings → Privacy & Security → Camera.
- "Permission denied" — Click the lock icon in your browser's address bar and set Camera to "Allow." On macOS, also check System Settings → Privacy & Security → Camera and ensure your browser is listed. On Windows, check Settings → Privacy → Camera.
- Dark or grainy image — Your lighting is the problem, not your camera. Face a window or place a desk lamp behind your monitor, pointing at your face. Avoid having bright windows behind you — this causes backlighting that makes your face appear dark.
- Low frame rate or stuttering — Close other tabs and applications. Video encoding is CPU-intensive. If your frame rate is below 15 FPS, your CPU is struggling. Check if other processes are using high CPU in Task Manager (Windows) or Activity Monitor (macOS).
Webcam Tips for Better Video Quality
Lighting is everything. A $30 webcam with good lighting looks better than a $200 webcam in a dark room. Use soft, diffused light from in front of you. Ring lights work well but even a well-positioned desk lamp makes a big difference. Avoid overhead fluorescent lighting, which creates unflattering shadows under your eyes.
Position your camera at eye level. Laptop cameras below eye level create an unflattering up-the-nose angle. Stack your laptop on books or use a laptop stand to bring the camera to eye level. For external webcams, mount them on top of your monitor. Before your next call, run a quick pre-meeting check to verify everything looks good.
