What this tool does
Live camera preview with resolution details
The preview shows what the other side will see, with the resolution the browser actually negotiated printed underneath it.
Microphone level meter that moves with your voice
The level meter moves with your voice, so you can tell a muted microphone from a working one before the call rather than during it.
Switch between your cameras and microphones
Where you have more than one camera or microphone, the dropdowns let you switch and test each in turn.
Clear permission and error messages
When permission is refused or a device is already in use by another app, the page says which of those happened instead of showing a blank box.
Nothing recorded, saved or uploaded
Nothing is recorded, saved or uploaded. The video and audio go from the device to the preview and no further.
Frequently asked questions
Is anything recorded or uploaded?
No. The camera and microphone feeds are shown live on your device only. Nothing is recorded, saved or sent anywhere, and everything stops when you close the page.
Why does it ask for permission?
Your browser must ask before any site can use your camera or microphone. The test cannot run until you allow access, and you can revoke it at any time in your browser settings.
My camera or mic will not start, what now?
Make sure no other app is using the device, that you allowed permission, and that you picked the right device in the dropdown. On a phone, check the site has camera and microphone permission.
Can I choose which camera or microphone to test?
Yes. Once you start a test the dropdowns fill with your available devices, and picking a different one switches to it straight away.
Does it work on my phone?
Yes, in most modern mobile browsers. You may need to allow camera and microphone access when prompted, and on iPhone it works in Safari.
