Web browser

A web browser displaying a web page

A web browser (also referred to as an Internet browser or simply a browser) is application software for accessing the World Wide Web or a local website. When a user requests a web page from a particular website, the web browser retrieves the necessary content from a web server and then displays the page on the user's device.

A web browser is not the same thing as a search engine, though the two are often confused.[1][2] A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed.[3]

Web browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser.[4] The most used browser is Google Chrome, with a 63% global market share on all devices, followed by Safari with 20%.[5]

In Hypertext Transfer Protocol technical texts, web browsers (and other clients) are commonly referred to as user agents.
