Web/API/NavigatorID/platform

Returns a string representing the platform of the browser. The specification allows browsers to always return the empty string, so don't rely on this property to get a reliable answer.

Syntax

platform = navigator.platform 

Value

A DOMString identifying the platform on which the browser is running, or an empty string if the browser declines to (or is unable to) identify the platform. platform is a string that must be an empty string or a string representing the platform on which the browser is executing.

For example: "MacIntel", "Win32", "FreeBSD i386", "WebTV OS"

Example

console.log(navigator.platform);

Usage notes

Most browsers, including Chrome, Edge, and Firefox 63 and later, return "Win32" even if running on a 64-bit version of Windows. Internet Explorer and versions of Firefox prior to version 63 still report "Win64".
