How to use the webcam test
- Tap Start camera test and allow camera access when your browser asks.
- Check that the preview shows a clear, correctly lit, in-focus image.
- If you have more than one camera, use the dropdown that appears to switch between them.
- Check the resolution and frame rate shown below the preview against what you expect for your device.
- Tap Stop to end the preview and turn off the camera indicator.
What this test checks
- Camera detection: confirms your operating system and browser can see the camera at all.
- Permission handling: confirms the site or app you're about to use will be able to request access without hitting a blocked setting.
- Image quality: lets you check focus, lighting, and framing before a call or recording.
- Resolution and frame rate: shows the actual capture settings your camera is delivering, not just its rated maximum.

Frequently asked questions
Does this tool record or save my video?
No. The feed is displayed live in your browser and never leaves your device. Nothing is recorded, stored, or sent to any server, and the feed disappears the moment you stop the test or close the page.
My browser says camera access is blocked. What do I do?
Check your browser's site settings for this page and set camera access to allowed, then reload and try again. On some systems you also need to grant your browser camera permission at the operating system level, separate from the browser's own setting.
Why is my preview mirrored?
The preview flips the image horizontally so it behaves like a mirror, which most people find more natural when looking at their own camera. It does not affect how you appear to other people on a call; that depends on the calling app, not this test.
Can I test an external USB webcam?
Yes. Plug it in before starting the test, and it should appear as an option in the camera dropdown once you grant permission, alongside any built-in camera.
Will this detect a virtual camera from software like OBS?
Usually yes, since virtual cameras register with your system the same way a physical one does. If it doesn't show up, confirm the virtual camera software is running and its output is started before you load this page.
The image looks dark or grainy. Is that my camera's fault?
Often it's the room, not the hardware. Low or uneven lighting is the most common cause of a dark or noisy image, even on good webcams. Try facing a window or adding a light source in front of you rather than behind.
