'''Konqueror''' is a [[Free and open-source software|free and open-source]] [[web browser]] and [[file manager]] that provides [[World Wide Web|web]] access and [[file viewer|file-viewer]] functionality for file systems (such as local files, files on a remote FTP server and files in a disk image). It forms a core part of the [[KDE Software Compilation]]. Developed by volunteers, Konqueror can run on most [[Unix-like]] [[operating system]]s. The [[KDE]] community licenses and distributes Konqueror under [[GNU General Public License|GNU GPL-2.0-or-later]].

The name "Konqueror" references the two primary competitors at the time of the browser's first release: "first comes the [[Netscape Navigator|Navigator]], then [[Internet Explorer|Explorer]], and then the Konqueror".<ref>

 |quote= Where does the name ''Konqueror'' come from? [...] It's a word play on the other browsers' names. After the Navigator and the Explorer comes the Conqueror; it's spelled with a K to show that it's part of KDE. The name change also moves away from "kfm" (the KDE file manager, Konqueror's predecessor) which represented only file management.

It also follows the [[KDE]] naming convention: the names of most KDE programs begin with the letter K.<ref>[http://docs.kde.org/stable/en/kdebase/faq/webbrowser.html#id2556978 K Desktop Environment (KDE)] {{webarchive|url=https://web.archive.org/web/20070609082659/http://docs.kde.org/stable/en/kdebase/faq/webbrowser.html |date=2007-06-09 }}</ref>

Konqueror first appeared with version 2 of KDE on October 23, 2000.<ref>[http://www.kde.org/announcements/announce-2.0.php K Desktop Environment - KDE 2.0 Release Announcement<!-- Bot generated title -->]</ref> It replaced its predecessor, KFM (KDE file manager).<ref>{{Cite web |url=http://konqueror.kde.org/faq/#WheredoesthenameiKonqueroricomefrom |title=Konqueror - Konqueror FAQ<!-- Bot generated title --> |access-date=2008-03-04 |archive-url=https://web.archive.org/web/20080723193818/http://konqueror.kde.org/faq#WheredoesthenameiKonqueroricomefrom |archive-date=2008-07-23 |url-status=dead }}</ref> With the release of KDE 4 in 2008, the functionalities of web browser and file manager were separated: [[Dolphin (file manager)|Dolphin]] replaced Konqueror as the default KDE file manager, while the KDE community continues to maintain Konqueror as the default KDE web browser.

==Major supported protocols==
Konqueror can utilize all [[KIO]]slaves installed on the user's system. Some examples include: 
* [[FTP]] and SFTP/SSH browser
* [[Samba (software)|Samba]] (Microsoft file-sharing) browser
* HTTP browser
* [[Internet Message Access Protocol|IMAP]] mail client
* ISO (CD image) viewer
* [[Virtual Network Computing|VNC]] viewer

A complete list is available in the KDE Info Center's Protocols section.

==User interface==
Konqueror supports [[Tab (GUI)|tabbed document interface]] and Split views, wherein a window can contain multiple documents in tabs. [[Multiple document interface]]s are not supported, however it is possible to recursively divide a window to view multiple documents simultaneously, or simply open another window.

Konqueror's [[user interface]] is somewhat reminiscent of [[Microsoft]]'s [[Internet Explorer]], though it is more customizable. It works extensively with "panels", which can be rearranged or added. For example, one could have an [[Internet bookmarks]] panel on the left side of the browser [[window (computing)|window]], and by clicking a bookmark, the respective [[web page]] would be viewed in the larger panel to the right. Alternatively, one could display a hierarchical list of [[Directory (computing)|folders]] in one panel and the content of the selected folder in another. Panels are quite flexible and can even include, among other [[KParts]] ([[software component|component]]s), a console window, a text editor, and a media player. Panel configurations can be saved, and there are some default configurations. (For example, "[[Midnight Commander]]" displays a screen split into two panels, where each one contains a folder, Web site, or file view.)

Navigation functions (back, forward, history, etc.) are available during all operations. Most keyboard shortcuts can be remapped using a graphical configuration, and navigation can be conducted through an assignment of letters to nodes on the active file by pressing the control key. The address bar has extensive autocompletion support for local directories, past [[Uniform Resource Locator|URL]]s, and past search terms.

==Web browser==
[[File:Konqueror 20.12.2 specifications screenshot.png |thumb|Konqueror specifications]]
Konqueror has been developed as an autonomous [[web browser]] project. It uses [[KHTML]] as its [[browser engine]], which is compliant with [[HTML]] and supports [[JavaScript]], [[Cascading Style Sheets|CSS]], [[Transport Layer Security|SSL]], and other relevant [[open standard]]s. An alternative layout engine, ''kwebkitpart'', is available from the [[Extragear]].<ref>{{cite web |url=http://techbase.kde.org/Projects/WebKit/Part |title=Projects/WebKit/Part - KDE TechBase |access-date=2010-03-30 |publisher=KDE TechBase}}</ref>

While KHTML is the default web-rendering engine, Konqueror is a modular application and other rendering engines are available. In particular, the WebKitPart component using the KHTML-derived [[WebKit]] engine has seen a lot of support in the KDE 4 series. However, the KHTML rendering backend contains unique features, such as the ability to save a full archive of any given webpage into a single file with the ".war" extension.

Konqueror integrates several customizable [[Web search engine|search services]] which can be accessed by entering the service's abbreviation code (for example, <code>gg:</code> for [[Google]], or <code>wp:</code> for [[Wikipedia]]) followed by the search term(s). One can add their own search service; for instance, to retrieve [[English Wikipedia]] articles, a shortcut may be added with the URL <code><nowiki>http://en.wikipedia.org/wiki/Special:Search?search=\{@}&go=Go</nowiki></code>.

KHTML's rendering speed is on par with that of competing browsers, but sites with customized JavaScript are often problematic due to KHTML's much smaller [[Mind share|mind-]] and [[Usage share of web browsers|market-share]], resulting in fewer JavaScript features built into the JS engine.

KJS is Konqueror's [[JavaScript engine]] that was originally developed by [[Harri Porten]] in 2000. On June 13, 2002, [[Maciej Stachowiak]] announced on a mailing list that [[Apple Inc.|Apple]] was releasing [[WebKit#JavaScriptCore|JavaScriptCore]], a framework for [[Mac OS X]] that was based on KJS.<ref name="JS-Core_Apple">{{cite web|url=http://www.opendarwin.org/pipermail/kde-darwin/2002-June/000034.html |title=[KDE-Darwin] JavaScriptCore, Apple's JavaScript framework based on KJS |last=Stachowiak |first=Maciej |date=2002-06-13 |publisher=opendarwin.org |archive-url=https://web.archive.org/web/20070310215550/http://www.opendarwin.org/pipermail/kde-darwin/2002-June/000034.html |archive-date=2007-03-10 |url-status=dead |access-date=2015-05-13 }}</ref>

[[Kubuntu]]'s 10.10 Maverick Meerkat release switched the default browser from Konqueror to rekonq, as well as a [[Firefox]] installer being added.<ref>{{cite web|last=Laishram|first=Ricky|title=Rekonq To Be The Default Web Browser In Kubuntu 10.10|url=http://techie-buzz.com/foss/rekonq-to-be-the-default-web-browser-in-kubuntu-10-10.html|publisher=Techie Buzz|access-date=7 May 2011}}</ref> Kubuntu subsequently switched from rekonq to Firefox, with the release of 14.04 Trusty Tahr.<ref>{{cite web|title=Kubuntu 14.04 LTS|url=http://www.kubuntu.org/news/kubuntu-14.04|publisher=Kubuntu.org|access-date=9 December 2014|url-status=dead|archive-url=https://web.archive.org/web/20141111234900/http://www.kubuntu.org/news/kubuntu-14.04|archive-date=11 November 2014}}</ref>

==File manager==
Konqueror also allows browsing the local directory hierarchy—either by entering locations in the address bar, or by selecting items in the file browser window. It allows browsing in different views, which differ in their usage of [[icon (computing)|icon]]s and layout. Files can also be [[execution (computing)|executed]], viewed, copied, moved, and deleted.

The user can also open an embedded version of [[Konsole]], via KDE's KParts technology, in which they can directly execute shell commands. In addition to the Konsole KPart, Konqueror can also use a [[Filelight]] KPart, to view a radial diagram of the user's filesystem.

Although this functionality has not been removed from Konqueror, as of KDE 4, [[Dolphin (file manager)|Dolphin]] has replaced Konqueror as the default file manager. Dolphin can – like Konqueror – divide each window or tab into multiple panes. Konqueror makes more powerful use of this feature, allowing as many vertically and horizontally divided panes as desired. Each can link to different content or even remote locations, so that Konqueror becomes a powerful graphical tool to manage content on multiple servers all in one window, "[[Drag and drop|dragging and dropping]]" files between locations.

</gallery>

==File viewer==
Using the [[KDE Platform#KParts|KParts]] [[object model]], Konqueror executes components that are capable of viewing (and sometimes editing) specific [[filetype]]s and embeds their client area directly into the Konqueror panel in which the respective files have been opened. This makes it possible to, for example, view an [[OpenDocument]] (via [[Calligra]]) or [[Portable Document Format|PDF]] document directly within Konqueror. Any application that implements the [[KParts]] model correctly can be embedded in this fashion.

KParts can also be used to embed certain types of multimedia content into HTML pages; for example, the <abbr title="Konqueror Media Player">KMPlayer</abbr> KPart enables Konqueror to show embedded video on web pages.

==KIO==
{{details|KIO}}
In addition to browsing files and websites, Konqueror utilizes [[KIO]] plugins to extend its capabilities well beyond those of other browsers and file managers. It uses components of KIO, the KDE I/O plugin system, to access different protocols such as [[HTTP]] and [[File Transfer Protocol|FTP]] (support for these is built-in), [[WebDAV]], [[Server Message Block|SMB]] (Windows shares), [[SSH File Transfer Protocol|SFTP]] and [[Files transferred over shell protocol|FISH]] (a handy replacement to the latter when the SFTP subsystem is disabled on the remote host).

Similarly, Konqueror can use KIO plugins (called IOslaves) to access [[ZIP (file format)|ZIP file]]s and other archives, to process ed2k links (edonkey/emule), or even to browse [[CD|audio CDs]], ("audiocd:/") and [[ripping|rip]] them via [[drag-and-drop]]. Likewise, the "man:" and "info:" IOslaves can be used to fetch [[man page|man]] and info formatted documentation.

==Konqueror Embedded==

[[Image:Konqueror-x11-embedded-linux.png|thumb|left|Konqueror Embedded on a Linux PDA]]
An [[embedded systems]] version, '''Konqueror Embedded''' was previously [https://web.archive.org/web/20190322005854/http://www.konqueror.org/embedded/ available]. Unlike the full version of Konqueror, Embedded Konqueror is purely a web browser. It does not require [[KDE]] or even the [[X window system]]. A single static library, it is designed to be as small as possible, while providing all necessary functions of a web browser, such as support for [[HTML]] 4, [[Cascading Style Sheets|CSS]], [[JavaScript]], [[HTTP cookie|cookies]], and [[Secure Sockets Layer|SSL]]. <ref>{{Cite web |url=https://www.linuxjournal.com/article/4767 |title=Konqueror/Embedded: An Open-Source Web Browser For EmbeddedLinux Systems |date=2001-09-01 |access-date=2024-04-09 |website=[[Linux Journal]] |last=Hausmann |first=Simon |publisher=Slashdot Media}}</ref>

'''KGet''' is a [[free software|free]] [[download manager]] for [[KDE]] and is the default download manager for Konqueror.  It is part of the KDE Network package. By default, it is the download manager used for Konqueror, but can also be used with [[Mozilla Firefox]] and Chromium-based web browsers<ref>{{cite web |url = http://fosswire.com/2008/07/23/using-kget-download-manager-with-firefox/ |title = Using KGet Download Manager with Firefox |first = Peter |last = Upfold |date = July 23, 2008 |publisher = FOSSwire |access-date = September 26, 2018 |archive-url = https://web.archive.org/web/20090211111820/http://fosswire.com/2008/07/23/using-kget-download-manager-with-firefox/ |archive-date = February 11, 2009 |url-status = dead }}</ref><ref>{{Cite web|last=Guilloux|first=Nicolas|date=2020-01-26|title=KGet-Integrator|url=https://github.com/NicolasGuilloux/KGet-Integrator|access-date=2021-12-29|website=GitHub}}</ref> as well as rekonq.
