Let's check your webcam.
See yourself live, check the resolution and frame rate, and switch cameras. Video never leaves your browser.
Press Start camera and allow access — your video stays on this device.
How the webcam test works
When you press Start camera, your browser shows the getUserMedia permission
prompt. Allow it and we attach the live camera stream straight to the preview — no plugins,
no upload, just your browser talking to your camera. The details panel reads the
resolution, facing direction and aspect ratio directly from the camera track, and the FPS
figure is measured live by counting the frames your camera actually delivers each second.
Snapshot draws the current frame onto an in-page canvas, and Record 5s captures a short clip with the MediaRecorder API. Both stay in memory on your device. Video never leaves your browser — nothing is uploaded, recorded remotely or stored, and the camera is released the moment you stop or leave the page.
What the readings mean
- Resolution — the pixel size of the stream (e.g. 1280×720). Most laptop webcams are 720p; external cams often do 1080p or more.
- FPS — frames per second, measured live. 30 is the norm; below ~15 looks choppy on calls (poor lighting often lowers it).
- Facing — whether the camera reports as front ("user") or rear ("environment") on phones and tablets.
- Aspect — the width-to-height shape of the frame, usually 16:9 or 4:3.
Webcam test FAQ
Is my video uploaded or recorded anywhere?
No. The preview is a local media stream that never leaves your browser. Snapshots and the optional 5-second clip are kept in memory on your device and vanish when you close the page — no frame is ever sent to a server.
Why does it say another app is using my camera?
Most webcams can only serve one app at a time, especially on Windows. Close Zoom, Teams, OBS or any other tab or app that might be holding the camera, then press Start camera again.
Does this webcam test work in Safari on iOS?
Yes — Safari on iPhone and iPad supports camera capture over HTTPS. If the preview doesn't start on its own (iOS can block autoplay in low-power mode), just tap the preview area once to kick it off.
Why is my preview mirrored?
We mirror the preview by default because that's how you're used to seeing yourself — like a mirror. People on your calls see the un-mirrored view. Use the Mirror button to toggle it.
My camera is blocked — how do I fix it?
Click the lock icon in the address bar, set Camera to Allow, and reload the page. If it still won't start, our Windows 11 and macOS webcam guides cover the system-level switches that commonly block cameras.
