Questions about Camera & Mic Test
Does it record or upload anything?
No. The camera and microphone are only previewed and analysed live in your browser through getUserMedia and the Web Audio API. Nothing is recorded, saved or sent anywhere, and the tracks stop when you press Stop.
Why does the browser ask for permission?
Accessing a camera or microphone always requires your explicit permission, and a secure (https) page. If you denied it, allow it in your browser’s site settings and try again.
About Camera & Mic Test
Check your webcam and microphone work with our free online Camera & Mic Test. 100% browser-based, fast, and private—no login or file uploads required.
These video tools cover quick clip jobs in the browser: compress a recording to a smaller file, or capture your screen and webcam with audio, then download the result straight away.
This tool runs in your browser. The file is not uploaded. Screen and webcam recording needs your permission and a modern browser; close other tabs while recording so the encoder gets enough CPU and the frame rate stays smooth.
