Konqueror is a free and open-source web browser and file manager that provides web access and 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 systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later.
The name "Konqueror" echoes a colonization paradigm to reference the two primary competitors at the time of the browser's first release: "first comes the Navigator, then Explorer, and then the Konqueror". It also follows the KDE naming convention: the names of most KDE programs begin with the letter K.
Konqueror first appeared with version 2 of KDE on October 23, 2000. It replaces its predecessor, KFM (KDE file manager). With the release of KDE 4, Dolphin replaced Konqueror as the default KDE file manager, but the KDE community continues to maintain Konqueror as the default KDE web browser.
Konqueror can utilize all KIOslaves installed on the user's system. Some examples include:
A complete list is available in the KDE Info Center's Protocols section.
Konqueror supports tabbed 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'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, 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 folders in one panel and the content of the selected folder in another. Panels are quite flexible and can even include, among other KParts (components), a console window, a text editor, 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 URLs, and past search terms.
While KHTML is the default web-rendering engine, Konqueror is a modular application and other rendering engines are available. Especially the WebKitPart that uses the KHTML-derived WebKit engine has seen a lot of support in the KDE 4 series. One thing to note, is when the KHTML rendering backend is chosen, the user can choose to make a full archive of any given webpage, which is stored in an archive file with the ".war" extension.
Konqueror integrates several customizable search services which can be accessed by entering the service's abbreviation code (for example, gg: for Google, or wp: 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
Kubuntu's 10.10 Maverick Meerkat release switched the default browser from Konqueror to rekonq. Kubuntu subsequently switched from rekonq to Firefox, with the release of 14.04 Trusty Tahr.
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 icons and layout. Files can also be 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 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 the KParts object model, Konqueror executes components that are capable of viewing (and sometimes editing) specific filetypes 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 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 KMPlayer KPart enables Konqueror to show embedded video on web pages.
Further information: KIO
In addition to browsing files and web sites, 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 FTP (support for these is built-in), WebDAV, SMB (Windows shares), SFTP and 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 files and other archives, to process ed2k links (edonkey/emule), or even to browse audio CDs, ("audiocd:/") and rip them via drag-and-drop. Likewise, the "man:" and "info:" IOslaves can be used to fetch man and info formatted documentation.

KGet is a 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 as well as rekonq. KGet was featured by Tux Magazine and Free Software Magazine.
On KDE 3, KGet 0.8.x, 1 supported HTTP/FTP download. On KDE Software Compilation 4, KGet 2 was released; it supported bandwidth throttling segmentation, multi-threading, and the BitTorrent protocol.
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.
