How it works
The tool reads publicly available properties in the browser, such as screen size, viewport, language and time zone. You can copy the data in JSON format.
Frequently asked questions
Does the tool identify my name or files?
No. It only shows technical properties that the browser exposes to the page.
Does the resolution change when I resize the window?
The physical screen resolution does not change, but the viewport does. The value is updated when you resize the window.
