[[File:Safari 15.png|thumb|right|A web browser ([[Safari (web browser)|Safari]]) displaying a [[web page]]]]
A '''web browser''', often shortened to '''browser''', is an [[Application software|application]] for accessing [[website]]s. When a [[User (computing)|user]] requests a [[web page]] from a particular website, the browser retrieves its [[Computer file|files]] from a [[web server]] and then displays the page on the user's screen. Browsers can also display content stored locally on the user's device.
Browsers are used on a range of devices, including [[desktop computer|desktops]], [[laptop]]s, [[tablet computer|tablets]], [[smartphone]]s, [[smartwatch]]es and [[Video game console|consoles]]. {{As of|2024}}, the most used browsers worldwide are [[Google Chrome]] (~66% [[market share]]), [[Safari (web browser)|Safari]] (~16%), [[Microsoft Edge|Edge]] (~6%), [[Firefox]] (~3%), [[Samsung Internet]] (~2%), and [[Opera (web browser)|Opera]] (~2%).<ref name="statcounter">{{cite web |title=Browser Market Share Worldwide |url=https://gs.statcounter.com/browser-market-share |access-date=21 March 2025 |publisher=[[StatCounter]]}}</ref><ref name="cloudflare">{{cite web|last=|first=|title=Browser Market Share Report for 2024 Q1|website=cloudflare.com|publisher=Cloudflare, Inc.|date=May 3, 2024|url=https://radar.cloudflare.com/reports/browser-market-share-2024-q1|access-date=March 22, 2025}}</ref> As of 2023, an estimated 5.4 billion people had used a browser.<ref>{{Cite web |title=World Internet Users Statistics and 2023 World Population Stats|url=https://www.internetworldstats.com/stats.htm |archive-url=https://web.archive.org/web/20240523140912/https://www.internetworldstats.com/stats.htm|access-date=21 March 2025 |website=www.internetworldstats.com|archive-date=23 May 2024|url-status=dead}}</ref>

[[File:Web browser demo.webm|thumb|Navigating to [[English Wikipedia]] using a web browser ([[Firefox]])]]
The purpose of a web browser is to fetch content and display it on the user's device.<ref>{{Cite web|url=https://www.reference.com/humanities-culture/purpose-browser-e61874e41999ede|title=What Is the Purpose of a Web Browser?|date=4 August 2015}}</ref> This process begins when the user inputs a [[Uniform Resource Locator]] (URL), such as ''<code><nowiki>https://en.wikipedia.org/</nowiki></code>'', into the browser's [[address bar]]. Virtually all URLs on [[World Wide Web|the Web]] start with either ''<code>http:</code>'' or ''<code>https:</code>'' which means they are retrieved with the [[HTTP|Hypertext Transfer Protocol]] (HTTP). For [[HTTPS|secure mode]] (HTTPS), the connection between the browser and [[web server]] is [[encryption|encrypted]], providing a [[communications security|secure]] and [[information privacy|private]] data transfer.<ref>{{Cite web |url=https://www.techtarget.com/whatis/definition/HTTP-Hypertext-Transfer-Protocol|title=What is HTTP and how does it work?

Requisite materials, including text, [[Style sheet (web development)|style sheets]], [[images]], and other types of [[Website#Multimedia and interactive content|multimedia]], are [[downloaded]] from the server. Once the materials have been downloaded, the web browser's [[Browser engine|engine]] (also known as a layout engine or rendering engine) is responsible for converting those resources into an interactive visual representation of the page on the user's device.<ref name=behindscene>{{cite web|url=http://taligarsiel.com/Projects/howbrowserswork1.htm|title=Behind the scenes of modern web browsers|publisher=Tali Garsiel|access-date=21 April 2018}}</ref> Modern web browsers also contain separate [[JavaScript engine]]s which enable more complex interactive applications inside the browser.<ref name="howBlinkWorks">{{cite web |title=How Blink Works |url=https://docs.google.com/document/d/1aitSOucL0VHZa9Z2vbRJSyAIsAz24kX8LFByQ5xQnUg |access-date=12 March 2024}}</ref> A web browser that does not render a [[graphical user interface]] is known as a [[headless browser]].
Web pages usually contain [[hyperlink]]s to other pages and resources. Each link contains a URL, and when it is [[point and click|clicked]] or [[touchscreen|tapped]], the browser navigates to the new resource. Most browsers use an internal [[web cache|cache]] of web page resources to improve loading times for subsequent visits to the same page. The cache can store many items, such as large images, so they do not need to be downloaded from the server again. Cached items are usually only stored for as long as the web server stipulates in its HTTP response messages.<ref>{{Cite book |last1=Nguyen |first1=Hoai Viet |last2=Lo Iacono |first2=Luigi |last3=Federrath |first3=Hannes |chapter=Systematic Analysis of Web Browser Caches |date=2018-10-03 |title=Proceedings of the 2nd International Conference on Web Studies |chapter-url=https://doi.org/10.1145/3240431.3240443 |series=WS.2 2018 |___location=New York, NY, USA |publisher=Association for Computing Machinery |pages=64–71 |doi=10.1145/3240431.3240443 |isbn=978-1-4503-6438-6}}</ref><ref>{{Cite journal |last1=Mishra |first1=Vikas |last2=Laperdrix |first2=Pierre |last3=Rudametkin |first3=Walter |last4=Rouvoy |first4=Romain |date=2021-04-01 |title=Déjà vu: Abusing Browser Cache Headers to Identify and Track Online Users |url=https://petsymposium.org/popets/2021/popets-2021-0033.php |journal=Proceedings on Privacy Enhancing Technologies |language=en |volume=2021 |issue=2 |pages=391–406 |doi=10.2478/popets-2021-0033 |issn=2299-0984|hdl=20.500.12210/57495 |hdl-access=free }}</ref>

==History==
{{Main|History of the web browser}}
The first web browser, called [[WorldWideWeb]], was created in 1990 by Sir [[Tim Berners-Lee]].<ref>{{cite web | url=https://www.w3.org/People/Berners-Lee/WorldWideWeb.html |title=Tim Berners-Lee: WorldWideWeb, the first Web client |publisher=[[World Wide Web Consortium]]}}</ref><ref>{{cite web |url=https://livinginternet.com/w/wi_browse.htm |title=Web Browser History |last=Stewart| first=William |archive-date=20 January 2011|archive-url=https://web.archive.org/web/20110120213137/http://www.livinginternet.com/w/wi_browse.htm |url-status=live}}</ref> He then recruited [[Nicola Pellow]] to write the [[Line Mode Browser]], which displayed web pages on [[dumb terminals]].<ref name=":5">{{Cite book|last1=Gillies |first1=James |last2=Cailliau |first2=R. |url=https://archive.org/details/howwebwasbornsto00gill|title=How the Web was Born: The Story of the World Wide Web |publisher=Oxford University Press|year=2000|isbn=0192862073 |pages=[https://archive.org/details/howwebwasbornsto00gill/page/6 6]|url-access=registration}}</ref> The [[Mosaic (web browser)|Mosaic]] web browser was released in April 1993, and was later credited as the first web browser to find mainstream popularity.<ref>{{Cite magazine |last=Calore |first=Michael |date=2010-04-22 |title=April 22, 1993: Mosaic Browser Lights Up Web With Color, Creativity |language=en-US |magazine=Wired |url=https://www.wired.com/2010/04/0422mosaic-web-browser/ |access-date=2022-10-31 |issn=1059-1028}}</ref><ref name="bloomberg">{{cite news |date=17 March 2011 |title=Bloomberg Game Changers: Marc Andreessen |publisher=Bloomberg |url=https://www.bloomberg.com/video/67758394 |access-date=7 December 2011}}</ref> Its innovative [[graphical user interface]] made the [[World Wide Web]] easy to navigate and thus more accessible to the average person. This, in turn, sparked the Internet boom of the 1990s, when the Web grew at a very rapid rate.<ref name="bloomberg" /> The lead developers of Mosaic then founded the [[Netscape]] corporation, which released the Mosaic-influenced [[Netscape Navigator]] in 1994. Navigator quickly became the [[Usage share of web browsers#Older reports (pre-2000)|most popular]] browser.<ref>{{Cite web|url=https://www.mwdwebsites.com/nj-web-design-web-browsers.html|title=The Evolution of the Web Browsers|last=Enzer|first=Larry|date=31 August 2018|website=Monmouth Web Developers|access-date=31 August 2018|archive-date=31 August 2018|archive-url=https://web.archive.org/web/20180831174847/https://www.mwdwebsites.com/nj-web-design-web-browsers.html|url-status=dead}}</ref>
[[Microsoft]]
[[Google]] debuted its [[Google Chrome|Chrome]] browser in 2008, which steadily took market share from Internet Explorer and became the most popular browser in 2012.<ref>{{cite web | url=https://digitaltrends-uploads-prod.s3.amazonaws.com/2011/09/net-applications-browser-market.jpg | title=Internet Explorer usage to plummet below 50 percent by mid-2012 | work=[[Digital Trends]] | date=3 September 2011 | format=[[JPEG]] | access-date=8 May 2021 | archive-date=20 November 2011 | archive-url=https://web.archive.org/web/20111120200340/http://www.digitaltrends.com/web/internet-explorer-usage-to-plummet-below-50-percent-by-mid-2012/attachment/net-applications-browser-market/ | url-status=dead }}</ref><ref>{{cite web |title=StatCounter April-May 2012 data |url=https://gs.statcounter.com/#browser-ww-monthly-201204-201205 |access-date=8 May 2021}}</ref> Chrome has [[usage share of web browsers|remained dominant]] ever since.<ref name="statcounter" /> In 2015, Microsoft replaced Internet Explorer with [[Microsoft Edge Legacy|Edge [Legacy]]] for the [[Windows 10]] release.<ref>{{Cite news |last=Gibbs |first=Samuel |date=2018-03-19 |title=Windows 10: Microsoft is looking to force people to use its Edge browser |url=https://www.theguardian.com/technology/2018/mar/19/windows-10-microsoft-force-people-edge-browser-windows-mail-chrome-firefox |access-date=2024-07-28 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref> In 2020, this legacy version was replaced by a new [[Chromium (web browser)|Chromium]]-based version of [[Microsoft Edge|Edge]].
Since the early 2000s, browsers have greatly expanded their [[HTML]], [[CSS]], [[JavaScript]], and [[multimedia]] capabilities. One reason has been to enable more sophisticated websites, such as [[Web application|web apps]]. Another factor is the significant increase of [[broadband]] connectivity in [[List of sovereign states by number of broadband Internet subscriptions|many parts]] of the world, enabling people to access data-intensive content, such as [[Streaming media|streaming]] [[high-definition video|HD video]] on [[YouTube]], that was not possible during the era of [[Dial-up Internet access|dial-up modems]].<ref>{{cite web |title=Dial-Up Internet Today: Understanding Its Lasting Influence |url=https://simeononsecurity.com/articles/modem-magic_-how-dial-up-internet-works-and-its-legacy-today/ |website=SimeonOnSecurity |access-date=21 February 2024}}</ref>
Starting in the mid-2020s, browsers with integrated [[artificial intelligence]] (AI) capabilities, known as [[AI browser]]s, have become increasingly common. This includes both new entrants to the browser market and established browsers that added AI features, such as Chrome with the [[Gemini (chatbot)|Gemini]] [[chatbot]] and Edge with the [[Microsoft Copilot|Copilot]] chatbot.<ref>{{cite web |last1=Loic |first1=Lando |date=26 January 2024 |title=AI Browsers Are Here, and These Are the 5 Best Options |url=https://www.makeuseof.com/best-ai-browsers/ |website=Make Use Of |access-date=24 July 2025}}</ref><ref>{{cite web |last1=Caswell |first1=Amanda |title=The rise of AI browsers is shaking up the web — here's why it matters |date=18 July 2025 |url=https://www.tomsguide.com/ai/the-rise-of-ai-browsers-is-shaking-up-the-web-heres-why-it-matters |website=Tom's Guide |access-date=24 July 2025}}</ref>

[[File:Chromium (web browser).png|thumb|right|220x220px|Traditional browser arrangement has [[user interface]] features above page content.]]
Common [[user interface]] (UI) features:
* Allowing the user to have multiple [[web page|pages]] open at the same time, either in different browser windows or in different [[Tab (interface)|tabs]] of the same window.
* ''Back'' and ''forward'' buttons to go back to the previous page visited or forward to the next one.
* A ''refresh'' or ''reload'' and a ''stop'' button to reload and cancel loading the current page. (In most browsers, the stop button is merged with the reload button.)
* A ''home'' button to return to the [[home page|start page]].
* An address bar to input the [[URL]] of a page and display it, and a search bar to input [[web query|queries]] into a [[search engine]]. (In most browsers, the search bar is merged with the address bar.)
While [[mobile browser]]s have similar UI features as [[desktop computer|desktop]] versions, the limitations of the often-smaller [[touchscreen|touch screen]]s require mobile UIs to be simpler.<ref>{{cite web |last1=Lee |first1=Simon |title=The Limitations Of Touch Interfaces |url=https://thisisglance.com/the-limitations-of-touch-interfaces/ |website=Glance |date=29 March 2019 |access-date=23 April 2021}}</ref> The difference is significant for users accustomed to [[keyboard shortcut]]s.<ref>{{cite web |title=Chrome keyboard shortcuts |url=https://support.google.com/chrome/answer/157179 |publisher=Google Inc. |access-date=23 April 2021}}</ref> [[Responsive web design]] is used to create websites that offer a consistent experience across the desktop and mobile versions of the website and across varying screen sizes.

Access to some web content — particularly [[streaming media|streaming services]] like Netflix, Disney+, and Spotify — is restricted by [[Digital Rights Management]] (DRM) software. A web browser is able to access DRM-restricted content through the use of a [[Content Decryption Module]] (CDM) such as [[Widevine]]. As of 2020, the CDMs used by dominant web browsers require browser providers to pay costly license fees, making it unfeasible for most independent open-source browsers to offer access to DRM-restricted content.<ref>{{cite web | last=Doctorow | first=Cory | title=Three years after the W3C approved a DRM standard, it's no longer possible to make a functional indie browser | website=Boing Boing | date=2020-01-08 | url=https://boingboing.net/2020/01/08/rip-open-web-platform.html | access-date=2025-03-22}}</ref>

The other two browsers in the top four are made from different [[codebase]]s. [[Safari (web browser)|Safari]], based on [[Apple Inc.|Apple]]'s [[WebKit]] code, is the second most popular web browser and is dominant on Apple devices, resulting in an 18% global share.<ref name="statcounter"/> [[Firefox]], in fourth place, with about 3% market share,<ref name="statcounter"/> is based on [[Mozilla]]'s code. Both of these codebases are open-source, so a number of small niche browsers are also made from them.

Web browsers are popular targets for [[hacker]]s, who exploit [[Vulnerability (computing)|security holes]] to steal information, destroy [[computer file|files]], and partake in other [[Malware|malicious]] activities. Browser vendors regularly patch these security holes, so users are strongly encouraged to keep their browser software updated. Other protection measures are [[antivirus software]] and being aware of [[Internet fraud|scams]].<ref>{{cite web |title=Simple Steps for Internet Safety |url=https://www.fbi.gov/news/stories/simple-steps-for-internet-safety |website=fbi.gov |publisher=[[Federal Bureau of Investigation]] |access-date=21 February 2024}}</ref>
