This webcam test asks the browser for camera access and shows the live feed at the resolution you select. It also reports the actual resolution and frame rate negotiated with your hardware — handy when a video-call app says your camera is "low quality" and you want to see what it's really delivering. Click Take Screenshot to save a frame as a PNG.
Common webcam issues
- Black or no preview — privacy shutter is closed, another app holds the camera, or browser permission was denied.
- Wrong camera in use — pick the right one in the dropdown above.
- Resolution lower than expected — your camera doesn't support the selected mode; the browser falls back automatically.
- Frame rate dropping — usually a CPU or USB-bandwidth issue, not the camera.
- Mirrored image — the mirror toggle flips the preview without affecting what other apps capture.
Frequently asked questions
Why does the webcam test ask for permission every time?
Browsers re-prompt if you didn't pick "Always allow". Use the camera icon in the address bar to set a persistent rule for this site.
Why is my 4K webcam showing 720p?
Either the browser negotiated a lower mode for bandwidth or the camera reports 4K only at lower frame rates the browser declined. Try a different quality option in the dropdown above.
Can I record video with the webcam test?
Not in this tool — it's a live preview and snapshot. The screenshot button saves a single frame as PNG; for full recording use a dedicated app.
Is the video uploaded anywhere?
No. The webcam test renders the feed entirely in your browser. No video is recorded, stored, or transmitted.
