Webcam Test (Free, Online)
A free tool to check your webcam feed, resolution, and aspect ratio right in your browser. Switch between multiple cameras and take snapshots — handy for checking your look before a video call or testing a built-in or external camera.
Usage Tips
- Check your framing, lighting, and camera angle on this page before a video call so you are not caught off guard once you are live.
- If multiple cameras are connected (built-in plus an external USB camera, for example), use the dropdown to switch between them and compare the results.
- Use "Take Snapshot" to capture a still image so you can calmly review your lighting and background.
- If the feed looks choppy or glitchy, check whether another app is already using the camera or a browser extension is interfering.
Frequently Asked Questions
Side Note — How browsers get access to your camera
The technology that lets browsers work with camera feeds is called the getUserMedia API, standardized as part of WebRTC. Major browsers began implementing it around 2013, and it is now a standard feature that lets pages access a camera or microphone without any plugin. Video calls used to require Flash or a dedicated plugin, but this API made it possible to do everything directly in the browser.
To protect user privacy, browsers are designed to always require an explicit permission prompt before granting camera access. Even after you grant it once, per-site permissions can be reviewed or revoked at any time from the browser's settings. If a site you do not recognize asks for camera access, it is safer to check who is behind it before allowing it.
Even the same physical camera can yield a different resolution or frame rate depending on how it is connected — built-in, USB, or through virtual-camera software, for example. If a video call looks off, a test tool like this one lets you check the resolution actually being captured, and switching cameras or connection methods can often fix the issue.
