Everything you need to know.
Simple results upfront. More detail whenever you need it.
Camera Test
Live readout from the active camera track. The frame rate is measured from the frames actually delivered.
Video Quality
Estimated live from your camera feed. Results depend on your lighting and background as much as on the camera — hold still for a few seconds for the most accurate reading. Runs entirely in your browser.
Start the test to get a grade.
Microphone Test
Echo cancellation, noise suppression and auto-gain are off, so the meter shows what your microphone really picks up. Normal speech should reach about −30 to −15 dB.
Speaker Test
Play a short tone on the selected output. Use Left and Right to check headphone channels.
Connection Check
Latency is timed with a few tiny requests to this site's own server. Video calls connect to other servers, so treat it as a rough guide.
Browser & Device Info
Microphone test: how to check and fix your mic
The microphone test measures audio input in your browser. Select the microphone test button, grant microphone permission, then speak normally to see the waveform and live level. If the meter does not move, verify your input device, browser permissions and operating-system mute controls.
How to test your webcam
- Select Start Test. Your browser will ask permission to use your camera and microphone — this prompt comes from the browser itself, not from this site.
- Check the readout. Your live picture, resolution, measured frame rate and audio level appear immediately in the panels above. If a picture shows up and the mic meter moves when you talk, both are working.
- Fix what's flagged. If a module shows "Blocked", "No sound" or a low grade, follow the fixes for that device below.
Troubleshooting
Camera shows "Blocked" or "Denied"
- Chrome / Edge: click the camera or settings icon at the left of the address bar, set Camera and Microphone to Allow, then reload.
- Safari (Mac): Safari › Settings for this website › Camera / Microphone › Allow.
- Firefox: click the crossed-out camera icon in the address bar and remove the block.
- Windows: Settings › Privacy & security › Camera — turn on “Let apps access your camera” and “Let desktop apps access your camera”.
- macOS: System Settings › Privacy & Security › Camera — enable your browser, then quit and reopen it.
Camera "in use" or black picture
- Close Zoom, Teams, Skype, OBS and any other browser tab using the camera — most cameras can only be used by one app at a time.
- Check for a physical privacy shutter or a camera on/off key (often F8 or F10 on laptops).
- Unplug and reconnect an external webcam, ideally straight into the computer instead of a hub.
Microphone shows "No sound"
- Pick the right microphone from the list — headsets, webcams and monitors often add their own.
- Check the mute switch on your headset and the input volume in your system sound settings.
- Bluetooth headsets switch to a lower-quality “headset” mode when the mic is used; that's normal.
No sound from the speaker test
- Check the volume and mute key, and that this browser tab isn't muted.
- If output selection isn't offered, your browser always uses the system default output — change it in your system sound settings.
Low quality grade
- Dark or grainy: light in front of you (a window or lamp behind the screen) is the biggest single improvement for any webcam.
- Overexposed: avoid sitting with a bright window behind you.
- Soft: wipe the lens and sit at arm's length so autofocus can lock on.
- Choppy (below 15 fps): many cameras lower their frame rate in dim light — more light usually fixes this too.
Frequently asked questions
How do I test my webcam online?
Open this page and select Start Test. Your browser will ask for camera and microphone permission — allow it, and your live video, measured frame rate, resolution and audio level appear immediately. No download or account is needed.
Why isn't my webcam showing up?
This is usually one of three causes: the browser was denied camera permission, another application (like Zoom or Teams) already has the camera open, or the camera driver needs a refresh. Check your browser's site settings, close other apps using the camera, and reconnect the device if it's external.
Does this site record or store my video?
No. All video and audio processing happens locally in your browser using the WebRTC and Web Audio APIs. Nothing is uploaded, recorded, or sent to a server — snapshots are saved straight to your own device.
How do I test my microphone online?
Once the test starts, the microphone module shows a live waveform and a decibel level meter. Speak at a normal volume from where you'll sit during the call: the bar should reach roughly the middle (around −30 to −15 dB). If it stays flat or shows No sound, check that the correct microphone is selected and that it isn't muted at the system level or by a hardware switch.
What is a good webcam resolution for video calls?
720p (1280 by 720) is the practical minimum for clear video calls, and 1080p (1920 by 1080) looks noticeably sharper on platforms that support it. Frame rate matters too — 24 to 30 fps is standard; below 15 fps looks noticeably choppy. Many cameras drop their frame rate in dim light, which is why this test shows the measured rate, not just the requested one.
Does this tool grade my webcam's video quality?
Yes. The Quality module analyzes your live video feed and scores sharpness, brightness, noise and contrast in real time, then combines them into an overall grade from A to F, with a tip for the weakest area. It's calculated locally in your browser from the pixels of your own feed. It's an estimate that depends on your lighting and scene as much as on the camera, so hold still and let your lighting settle for the most accurate reading.
