Bookmarklets are small cross-platform JavaScript programs that can be contained as URLs within the bookmarks of most popular web browsers, or within hyperlinks on a web page. Because Microsoft Internet Explorer uses the term favorites instead of bookmarks, they are also less commonly called favelets.

Bookmarklets can be saved and used like normal webpage bookmarks. They are therefore simple "one click" tools which can add substantial functionality to the browser, for example:

  • Modify the way a web page is displayed within the browser (change the font size, background color etc.)
  • Extract data from a web page (links, images, text ..)
  • Jump directly to a search engine, with the search term(s) input either from a pop up[?] dialog box or from a selection already made on the web page
  • Submit the page to a validation service and display the results

The first Bookmarklets were named and created by Steve Kangas of www.bookmarklets.com (http://www.bookmarklets.com/) from an idea suggested in the Netscape JavaScript Guide.
