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>
