A webcam can technically work and still create a bad first impression. The camera may be pointed too low, the lighting may be harsh, the wrong device may be selected, or the image may be mirrored in a confusing way.

That is why previewing the camera before a recording, interview, class, or livestream is a useful habit. A webcam test online gives you a quick browser-based way to see what the camera is actually showing before you open the main app.

The first thing to check is device selection. Many laptops, monitors, and USB webcams appear as separate options. If the wrong one opens, fix it before joining the call.

Next, check framing. Your face should be visible, the camera should not point too far above or below you, and the background should not distract from the conversation. Then check lighting. A bright window behind you can make your face dark, while a small lamp in front of you can improve visibility quickly.

For streamers and creators, a preview also helps catch technical issues before recording. You can confirm resolution, image stability, and whether another app is already using the camera.

This is a simple step, but it saves time. When the camera looks right before the session starts, you can focus on the conversation or content instead of adjusting settings in front of everyone.
