Measured FPS counts the frames your browser actually receives each second. Low light often makes webcams drop to 15 fps or less.
Frequently asked questions
How do I know if my webcam is working?
Start the test and allow access. If you see yourself in the preview and the resolution figure appears, the camera works in your browser. A black preview usually means a privacy shutter, a hardware switch, or another app holding the camera.
Why does my camera say it is in use?
Most systems let only one app use a webcam at a time. Close Zoom, Teams, Skype, OBS, or other browser tabs with a call open, then press Try again.
What resolution is my webcam?
Pick the highest requested resolution and read the big figure: that is the size of the frames the camera is actually sending. In Chromium browsers the max resolution box also shows the largest mode the camera reports.
Why is my webcam frame rate low?
Webcams lengthen their exposure in dim light, which caps frames per second, often at 15 fps. Add light in front of you, close other apps using the camera, and try a lower resolution if USB bandwidth is limited.
Is this webcam test private?
Yes. The preview is drawn locally from your camera stream. Nothing is sent to a server, and the snapshot is created in your browser and saved straight to your device.
