About MicCheck Online
Free, instant, browser-based tools to test your audio and video devices — no download, no account, no data collected.
What is MicCheck Online?
MicCheck Online is a free collection of browser-based hardware testing tools. We help people quickly verify that their microphone, webcam, speakers, headphones, keyboard, and mouse are working correctly — all from within a web browser, with zero installation required.
Whether you are preparing for a video call, troubleshooting an audio issue, testing a new device, or verifying your setup before a livestream, MicCheck Online gives you instant, accurate results in seconds.
Why We Built It
We built MicCheck Online because testing hardware should be simple. Most people who wonder “is my mic working?” before a Zoom call or job interview do not want to download software, create an account, or navigate confusing OS settings menus. They just want a quick, honest answer.
Modern browsers already have everything needed to test audio and video devices through the WebRTC and Web Audio APIs. We built clean, focused tools on top of these APIs so anyone can run a complete hardware check in under two minutes — for free, forever.
🔒 Our Privacy Commitment
Privacy is not an afterthought for us — it is the foundation of how these tools work. When you test your microphone or webcam on MicCheck Online, your audio and video streams never leave your device. All processing happens locally inside your browser using standard Web APIs.
- ✓We do not record your audio, video, or keystrokes
- ✓We do not store any personal data
- ✓We do not require an account or email address
- ✓We do not sell data to third parties
- ✓All tool processing is local — your browser, your device, your data
