What information does the Browser Info Checker show?

It shows your browser name and version, operating system, user agent string, screen resolution, viewport size, color depth, device pixel ratio, system language, timezone, cookies enabled, online status, CPU cores, device memory, touch support and WebGL support.

Does the viewport size update when I resize the window?

Yes. The viewport width and height values update live every time you resize the browser window, so you can see the exact size at any moment.

What does the quick checks button do?

It runs four quick checks — cookies, online status, WebGL support and touch support — and reports a Pass or Warning result for each one.

Is any of my information sent to a server?

No. All detection happens with JavaScript inside your browser, and the copy button only copies the table text to your clipboard. Nothing is uploaded or stored.

If WebGL shows "Not supported", some sites and games may not render correctly.
Device memory and CPU cores are estimates reported by the browser and may not be exact.
