About this tool

Webcam Test plays your camera in a local <video> element and reports what the browser actually delivers, so you can confirm the device works before joining a meeting, recording a video, or troubleshooting an app that says it cannot find a camera. The diagnostics panel reads MediaStreamTrack.getSettings() and shows the live resolution, aspect ratio, the frame rate the browser reports, a measured frame rate sampled from the preview, and the facing mode when the device exposes it (user for a selfie camera, environment for a rear camera on a phone or tablet). The device picker lists every video input the browser is willing to share, including laptop internal cameras, USB webcams, virtual cameras from OBS or Snap Camera, and capture cards; switching cameras restarts the stream with the new device. A mirror toggle flips the preview horizontally because most video apps mirror the front camera, and the snapshot button paints the current frame onto a canvas and downloads it as a PNG so you can verify the image looks right on disk. Everything runs in your browser. No frames are uploaded. Pressing Stop calls track.stop() on every track, which is the standard way to release the camera and turn off the operating system indicator. The tool needs a secure context (https or localhost) and modern browser support for the MediaDevices API; it gracefully reports browser permission errors with plain-English explanations and a fix.
