About this test
The webcam test opens your camera in the browser and reports what it actually delivers: resolution, frames per second, aspect ratio and the camera's maximum capability. Switch between cameras, mirror the image and save a snapshot. Video is processed locally and is never uploaded.
How to use this test
- Click Start camera and allow access when your browser asks.
- Choose your camera and resolution from the menus.
- Check the frame rate and image. Low FPS often means poor lighting or a USB bandwidth limit.
Frequently asked questions
Why is my webcam black or not found?
Another app may be using it, the privacy shutter may be closed, or camera access is blocked. See our webcam fix guide.
Is my video recorded?
No. The stream is shown only on this page and stops when you leave.
