Webcam Tester - Test Your Camera Online

A comprehensive online webcam testing tool that helps you check if your camera is working correctly.

Perfect for verifying camera setup before important video calls, streaming sessions, or content recording.

How do I test my webcam?

Testing your webcam is simple:

1. Click 'Start Camera' to begin
2. Allow camera access when prompted by your browser
3. Your camera feed will appear in the preview area
4. Check the actual resolution, aspect ratio, and FPS below
5. Try different cameras if you have multiple
6. Adjust resolution and frame rate settings
7. Use mirror and grid options to check alignment
8. Take snapshots to test image quality

The tool will show real-time camera information and let you verify everything is working properly.

Why is my camera not working?

If your camera isn't working, try these troubleshooting steps:

1. Check browser permissions: Make sure you clicked 'Allow' when asked for camera access
2. Check if another app is using the camera (Zoom, Skype, etc.)
3. Try a different browser (Chrome, Firefox, Edge)
4. Check if the camera is properly connected
5. Restart your browser
6. Check device manager (Windows) or System Preferences (Mac) to ensure the camera is recognized
7. Update camera drivers
8. Try a different USB port (for external cameras)

The error message will help identify the specific issue.

What resolutions can I test?

The webcam tester supports multiple resolutions:

- 4K (3840x2160): Ultra high definition
- 1080p (1920x1080): Full HD - recommended for most uses
- 720p (1280x720): HD - good for video calls
- 480p (854x480): Standard definition
- 360p (640x360): Low quality - for slow connections

Note: Your camera must support the selected resolution. The tool will show the actual resolution your camera provides, which may differ from the requested resolution if your hardware doesn't support it.

Can I test multiple cameras?

Yes! If you have multiple cameras connected:

1. All detected cameras appear in the 'Select Camera' dropdown
2. Choose any camera from the list
3. Use the 'Switch Camera' button to quickly cycle between cameras
4. The tool works with:
- Built-in laptop cameras
- External USB webcams
- Multiple monitors with built-in cameras
- USB capture cards

Each camera can have different capabilities, so test each one to see which provides the best quality.

What is the Mirror Video option?

The 'Mirror Video' option flips your camera feed horizontally:

- Enabled (default): Shows a mirrored view, like looking in a mirror
- Disabled: Shows the actual view that others see

Most people prefer the mirrored view because it's more intuitive (when you move right, the image moves right). However, text and logos will appear backwards when mirrored.

This setting only affects your preview - it doesn't change how others see you in video calls.

What is the Grid overlay for?

The grid overlay helps with:

1. Composition: Position yourself using the rule of thirds
2. Alignment: Ensure the camera is level and centered
3. Framing: Check what's visible in the shot
4. Positioning: Adjust your camera angle for better framing

The grid divides the preview into a 3x3 layout, which is a standard photography composition guide. It's especially useful when setting up your camera for professional video calls or content creation.

How do snapshots work?

The snapshot feature captures a still image from your camera:

1. Click 'Take Snapshot' while the camera is running
2. The current frame is captured and displayed below
3. Review the snapshot quality
4. Click 'Download Snapshot' to save the image as PNG
5. The filename includes a timestamp for easy organization

Snapshots are useful for:
- Testing image quality before important calls
- Checking lighting and background
- Saving reference images of your setup
- Verifying camera clarity and focus

Is my video private?

Yes, your privacy is completely protected:

- All camera processing happens locally in your browser
- No video is uploaded to any server
- No recording or storage of your camera feed
- No data is sent over the internet
- The tool works entirely offline (after page load)
- Only you can see your camera feed
- Snapshots are only saved if you choose to download them

The tool is 100% client-side, ensuring complete privacy and security.
