Camera & Microphone Tester
Test camera and microphone functionality, record media, and monitor audio levels
100% Local Processing
All camera and microphone data is processed entirely in your browser. Nothing is uploaded to any server.
No Data Collection
We don't collect, store, or analyze any of your audio or video content. Your data stays on your device.
No Cloud Storage
Recordings are stored temporarily in your browser's memory only. Nothing is saved to external servers.
You Control Downloads
Only you decide what recordings to download to your computer. We never automatically save anything.
Standard Browser Security
Uses secure WebRTC APIs. Your browser controls all permissions and access to your devices.
Open Source & Transparent
This tool is open source - you can inspect the code to verify our privacy claims.
đź”’ How it works: When you start the camera or microphone, your browser requests permission and creates a local media stream. All audio analysis, video processing, and recording happens on your device using standard web technologies. No network requests are made for media processing.
