How to Test Your Camera
Get your webcam tested in seconds with these simple steps. No software installation required.
Click "Start Camera"
Press the Start Camera button. Your browser will ask for camera permission — click Allow. Your webcam stream will appear instantly in the preview area.
Check Camera Quality
View the live stats overlay showing your camera's resolution and FPS. Use the panel controls to adjust brightness, contrast, saturation, and zoom to check your camera's capabilities.
Capture & Compare
Use the Capture button to take screenshots and evaluate image quality. Try different resolutions and FPS settings using the panel dropdowns to find the best setup for your needs.
Everything You Need to Test Your Webcam
A professional-grade camera diagnostic tool that runs entirely in your browser. Your video never leaves your device.
Live Resolution Detection
Automatically detects and displays your camera's actual output resolution in real-time, including width, height, and aspect ratio.
FPS Measurement
Measure your webcam's actual frames-per-second in real-time. Test whether your camera achieves 30 FPS, 60 FPS, or another rate.
Brightness & Contrast
Adjust brightness, contrast, and saturation via CSS filter controls to see how your camera handles different lighting conditions.
Multi-Camera Support
If you have multiple cameras (built-in + external webcam), easily switch between them using the device selector to test each one.
Screenshot Capture
Capture still images from your webcam directly in the browser. View thumbnails and download individual snapshots to your device.
100% Private & Secure
All processing happens locally in your browser using the WebRTC API. Your camera feed is never uploaded or transmitted to any server.
Frequently Asked Questions
Everything you need to know about testing your webcam online.
Most camera issues are permission-related. Make sure you click "Allow" when your browser prompts for camera access. If you previously denied permission, click the camera icon in your browser's address bar to reset it. Also ensure no other application (Zoom, Teams, Skype) is using the camera simultaneously. On mobile, check your browser app's camera permissions in your device settings.
Yes! The Camera Test tool works on all modern smartphones and tablets. On iOS, it works in Safari and Chrome. On Android, it works in Chrome, Firefox, and other modern browsers. You can even switch between the front (selfie) and rear camera using the device selector that appears after granting camera permission.
Absolutely not. This tool uses the browser's built-in WebRTC (Web Real-Time Communication) API, which provides direct access to your camera hardware. All video processing and display happens locally on your device. Nothing is uploaded, recorded, or transmitted. We cannot see your camera feed at all — we don't even have a server to receive it.
FPS stands for Frames Per Second — how many images your camera captures and displays every second. Most webcams support 30 FPS, while high-quality cameras support 60 FPS. A higher FPS means smoother video, which is especially important for video calls and streaming. If your FPS is lower than expected, it could indicate poor lighting, a USB bandwidth issue, or background apps consuming resources.
After starting the camera, you'll see the current resolution displayed in the stats overlay (e.g., "1920×1080"). You can also use the Resolution dropdown in the settings panel to request a specific resolution and see if your camera supports it. Note that the actual delivered resolution may be limited by your camera hardware — requesting 4K won't upgrade an HD webcam.
Browser-based camera access uses the WebRTC media constraints API, which negotiates resolution with your hardware and OS drivers. The browser may choose a different resolution based on available system resources, USB bandwidth, or driver limitations. Some cameras also have firmware-level resolution limits that override software requests.
A black screen usually means the camera is accessed but not outputting video. Try: (1) Check if a physical lens cover is closed. (2) Restart your browser and try again. (3) Check if another app has exclusive camera access. (4) Update your webcam drivers (Windows) or check System Preferences › Security & Privacy (Mac). (5) Try selecting a different camera from the device dropdown if you have multiple cameras connected.
