About this tool
Before a video call, it's worth five seconds to confirm your webcam actually works — and that the lens isn't pointed at your ceiling. This tool asks your browser for camera access, previews the live stream, and reports the resolution and frame rate it's using. Nothing is recorded and nothing is uploaded; the stream closes the moment you click Stop or navigate away. Permission errors are shown in plain language rather than cryptic browser codes.
Frequently asked questions
Is the video being recorded?
No. Your webcam stream stays on your device and is used only for the live preview. It's released the instant you click Stop or leave the page. No frames are uploaded or stored.
Why is my resolution so low?
The browser picks the best resolution the camera offers that matches the requested settings — but some webcams cap at 720p or 480p, and privacy extensions can limit it further. The resolution shown is what the camera actually delivered.
The preview is black — what's happening?
Usually the camera's physical shutter is closed, the lens is covered, or another app (Zoom, Teams, OBS) is holding the camera exclusively. Close other apps and try again.
