Webcam Not Working? Here's How to Test It Instantly Online
⚡ Quick Answer
If your webcam isn't working, go to a free browser-based webcam test tool and allow camera access. If you can see a live preview, your camera is functioning — the problem is likely in the app or settings. If no image appears, it may be a driver, privacy, or hardware issue.

Browser Says "No Camera Found"
Check no other app is using the webcam (Zoom, Teams, Skype all lock the camera). Close all video apps, refresh the tester, and check Device Manager on Windows to see if the webcam appears.

The hardware is fine — the problem is app-specific. In Zoom: Settings → Video → select the correct camera. In Teams: Settings → Devices → Camera.
Camera Works But Image Is Poor Quality
Clean the lens with a soft cloth. Sit facing a light source. Check if your driver limits resolution and update it via Device Manager.
