How to test your webcam
- Press Start webcam test and allow camera access.
- Check the preview, the resolution (720p = HD, 1080p = Full HD) and the measured frame rate (30 fps is smooth).
- Switch between built-in, USB and phone cameras in the list.
- Take a photo to check focus and lighting.
Camera not working? Try this
- Black screen: some laptops have a privacy shutter or a camera key (often F8 or F10). Check it is open.
- Permission denied: allow the camera from the address-bar icon and reload.
- “In use by another app”: only one app can use most webcams at once — close Zoom, Teams, Skype or OBS.
- Windows: Settings → Privacy & security → Camera → allow access. Mac: System Settings → Privacy & Security → Camera.
- Low frame rate: usually poor lighting — cameras slow down to let in more light. Face a window or lamp.
Is it private?
Yes. The test runs entirely in your browser. Your camera is requested only after you press Start, is never uploaded or stored, and is switched off when you press Stop or close the page. You can revoke the permission at any time from the padlock icon in your browser’s address bar.

Frequently asked questions
Why is the preview mirrored?
Mirroring feels natural, like a mirror. Other people on a call see you un-mirrored. Untick Mirror to see what they see.
Is the video recorded?
No. It is shown only in your browser and never uploaded.
Why is my resolution lower than advertised?
Browsers may pick a lower mode in poor light or over USB 2.0, and some laptop cameras are only 720p even if marketed as HD.
