Konqueror is afree and open-sourceweb browser andfile manager that providesweb access andfile-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 theKDE Software Compilation. Developed by volunteers, Konqueror can run on mostUnix-likeoperating systems. TheKDE community licenses and distributes Konqueror underGNU GPL-2.0-or-later.
The name "Konqueror" references the two primary competitors at the time of the browser's first release: "first comes theNavigator, thenExplorer, and then the Konqueror".[2]It also follows theKDE naming convention: the names of most KDE programs begin with the letter K.[3]
Konqueror first appeared with version 2 of KDE on October 23, 2000.[4] It replaced its predecessor, KFM (KDE file manager).[5] With the release of KDE 4 in 2008, the functionalities of web browser and file manager were separated:Dolphin replaced Konqueror as the default KDE file manager, while the KDE community continues to maintain Konqueror as the default KDE web browser.
Konqueror can utilize allKIOslaves installed on the user's system. Some examples include:
A complete list is available in the KDE Info Center's Protocols section.
Konqueror supportstabbed document interface and Split views, wherein a window can contain multiple documents in tabs.Multiple document interfaces are not supported, however it is possible to recursively divide a window to view multiple documents simultaneously, or simply open another window.
Konqueror'suser interface is somewhat reminiscent ofMicrosoft'sInternet Explorer, though it is more customizable. It works extensively with "panels", which can be rearranged or added. For example, one could have anInternet bookmarks panel on the left side of the browserwindow, and by clicking a bookmark, the respectiveweb page would be viewed in the larger panel to the right. Alternatively, one could display a hierarchical list offolders in one panel and the content of the selected folder in another. Panels are quite flexible and can even include, among otherKParts (components), 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, pastURLs, and past search terms.
Konqueror has been developed as an autonomousweb browser project. It usesKHTML as itsbrowser engine, which is compliant withHTML and supportsJavaScript,CSS,SSL, and other relevantopen standards. An alternative layout engine,kwebkitpart, is available from theExtragear.[6]
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-derivedWebKit 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 customizablesearch services which can be accessed by entering the service's abbreviation code (for example,gg: forGoogle, orwp: forWikipedia) followed by the search terms. One can add their own search service; for instance, to retrieveEnglish Wikipedia articles, a shortcut may be added with the URLhttp://en.wikipedia.org/wiki/Special:Search?search=\{@}&go=Go.
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 smallermind- andmarket-share, resulting in fewer JavaScript features built into the JS engine.
KJS is Konqueror'sJavaScript engine that was originally developed byHarri Porten in 2000. On June 13, 2002,Maciej Stachowiak announced on a mailing list thatApple was releasingJavaScriptCore, a framework forMac OS X that was based on KJS.[7]
Kubuntu's 10.10 Maverick Meerkat release switched the default browser from Konqueror to rekonq, as well as aFirefox installer being added.[8] Kubuntu subsequently switched from rekonq to Firefox, with the release of 14.04 Trusty Tahr.[9]
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 oficons and layout. Files can also beexecuted, viewed, copied, moved, and deleted.
The user can also open an embedded version ofKonsole, via KDE's KParts technology, in which they can directly execute shell commands. In addition to the Konsole KPart, Konqueror can also use aFilelight 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 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, "dragging and dropping" files between locations.
Using theKPartsobject model, Konqueror executes components that are capable of viewing (and sometimes editing) specificfiletypes 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 anOpenDocument (viaCalligra) orPDF document directly within Konqueror. Any application that implements theKParts 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, theKMPlayer KPart enables Konqueror to show embedded video on web pages.
In addition to browsing files and websites, Konqueror utilizesKIO 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 asHTTP andFTP (support for these is built-in),WebDAV,SMB (Windows shares),SFTP andFISH (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 accessZIP files and other archives, to process ed2k links (edonkey/emule), or even to browseaudio CDs, ("audiocd:/") andrip them viadrag-and-drop. Likewise, the "man:" and "info:" IOslaves can be used to fetchman and info formatted documentation.
Anembedded systems version,Konqueror Embedded was previouslyavailable. Unlike the full version of Konqueror, Embedded Konqueror is purely a web browser. It does not requireKDE or even theX 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 forHTML 4,CSS,JavaScript,cookies, andSSL.[10]
As of June 2019, this project's page on the KDE website has been taken down.[11]

KGet is afreedownload manager forKDE 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 withMozilla Firefox and Chromium-based web browsers[14][15] as well as rekonq. KGet was featured byTux Magazine[16] andFree Software Magazine.[17]
OnKDE 3, KGet 0.8.x, 1 supported HTTP/FTP download.[18]OnKDE Software Compilation 4, KGet 2 was released; it supportedbandwidth throttling segmentation, multi-threading, and theBitTorrent protocol.[17]
Where does the nameKonqueror 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.
