Test Your Camera and Microphone Before a Call
Webcam and mic tester opens your camera and microphone in the browser so you can see and hear exactly what a call would show, before you join one. Press start, grant permission, and watch the live preview and the audio meter move as you speak.
If something looks or sounds wrong, you catch it here instead of in front of a client or an interviewer.
What you get:
- A live video preview at the resolution your camera supports, mirrored so it looks the way others will see you
- An audio level meter that moves as you speak, so you can confirm your microphone is picked up
- Pause and resume while you record a short test clip
- Save the clip to review it: one recording free, up to 45 minutes
The test uses your browser’s default camera and microphone. Nothing uploads until you press Save Recording.
How to Test Your Camera and Mic
- Start the test: Click Start Test and allow the browser’s camera and microphone prompt.
- Check the preview and the meter: Watch the video preview and speak a few words to see the audio meter respond. Pause if you need to adjust lighting or move the microphone.
- Save a clip if you want one: Stop recording to upload the test clip to your ScreenApp account, where you can play it back later.
Lighting and microphone placement affect what the test shows more than the camera itself. A window in front of you beats one behind you, and a microphone close to your mouth beats your laptop’s built-in mic across a desk.
Webcam and Mic Tester vs Other Tools
| Feature | ScreenApp | Webcammictest.com | Loom | Webcamtests.com |
|---|---|---|---|---|
| No signup required | Yes | Yes | Yes | Yes |
| Camera and mic tested together | Yes | Yes | Separately | No, camera only |
| Save a test recording | Yes, uploads to your account | Yes, downloads locally | Not stated | Not stated |
| Switch between multiple devices | No | Yes | Yes | Yes |
| Test data stays on your device | No, saved clip uploads to your account | Yes | Not stated | Not stated |
- vs Webcammictest.com: Their tool says “everything runs locally in your browser, no video is uploaded, stored, or shared,” and it lets you switch cameras with a device selector. ScreenApp’s test clip uploads to your account instead of staying local, but it opens later from any device you sign into.
- vs Loom: Loom tests your webcam and microphone separately, then points you at the full Loom recorder, and its own device menu can switch between an external webcam or microphone. ScreenApp tests both in one live preview, but currently uses your browser’s default device.
- vs Webcamtests.com: A camera-only tool with its own device selector for switching between multiple webcams; it links out to a separate mic test tool. ScreenApp checks the camera and the microphone on the same page.
Who Needs a Webcam and Mic Test
Remote workers check their camera and microphone before client meetings and team standups. Once your gear checks out, record the actual meeting instead of taking notes by hand.
Job candidates verify their equipment before a video interview. Seeing the live preview shows what the interviewer will actually see, so the technology is not the thing you are thinking about when the call starts.
Teachers and students check their setup before an online class starts, so the first few minutes are not spent troubleshooting audio or video instead of teaching or learning.
Content creators confirm framing, lighting, and audio levels before they start recording, so they are not fixing avoidable problems after the fact.
Sales professionals and event speakers test their camera and microphone before a demo or a virtual presentation, when a bad connection or a muted mic costs more than a few minutes.
FAQ
What is a webcam and mic tester?
It is a browser tool that opens your camera and microphone so you can see a live video preview and watch an audio meter respond as you speak, before you join a call. It runs on the page you are on now.
How do I test my camera and microphone online?
Click Start Test and allow the browser’s permission prompt. Watch the video preview and say a few words to see the audio meter move. If you want to keep a copy, stop recording to save the clip.
Is the webcam and mic test free?
Yes, checking your camera and microphone with the live preview and meter costs nothing. If you save a test clip, it counts as your free plan’s one recording, up to 45 minutes.
Does it work on a phone?
Yes, it works in mobile browsers that support camera and microphone access, the same way it works on desktop.
Why isn’t my webcam showing up?
Check that no other application is already using the camera, allow camera and microphone access when your browser prompts you (or from the address bar’s camera icon), and confirm your operating system has not blocked the browser from the camera.
Can I switch between multiple cameras or microphones?
Not from this page. The test uses your browser’s default camera and microphone. To test a different device, set it as the default in your browser or operating system settings, then reload the page.
Does the test record anything?
The live preview and audio meter stay in your browser and are never uploaded. If you press Save Recording, that clip uploads to your ScreenApp account, encrypted with AES-256, and is only shared if you create a share link.
