Free Browser Media Test
WebRTC Test
Check whether your browser can access a camera, microphone, screen-share stream, and connected media devices before a meeting, class, stream, or recording.
The checks run in your current browser session. Media previews stay local and are stopped when you stop the test.
Browser media check
Verify the media APIs your next call or recording needs.
Before a call
Test the full browser media path.
Camera, microphone, device enumeration, and screen sharing each use a different browser permission or API path.
What does a WebRTC test check?
This WebRTC test checks browser access to camera and microphone input, screen sharing, media device enumeration, and local preview playback. It is useful before Zoom, Google Meet, Microsoft Teams, browser recording, online classes, and live streaming.
Why does WebRTC need permission?
Browsers require explicit permission before a website can read camera, microphone, or screen content. Permission is requested only after you press a test button. If access fails, review browser site settings and operating system privacy controls.
Does this WebRTC test upload video or audio?
No. The camera, microphone, and screen-share checks are local browser previews. This page does not create a call server or upload media for the check.
WebRTC troubleshooting
If a device is missing, reconnect it and scan again. If a permission prompt does not appear, open the site settings near the browser address bar and allow the relevant device. Close other meeting or recording apps that may already be using the camera or microphone.

WebRTC Test FAQ
Can I test screen sharing without joining a call?
Yes. Start Screen Share and choose a tab, window, or screen. The selected stream appears locally until you stop it.
Why are device names hidden?
Browsers often hide device labels until the page has permission to use a camera or microphone. The device count can still be available before labels are revealed.
