In computing, a plugin (or plug-in, add-in, addin, add-on, or addon) is a software component that adds a specific feature to an existing computer program). When a program supports plugins, it enables customization, allowing users to add the functions they want when they want them. Plugins are software extensions that can be loaded on a program to improve its functionality. They allow you to customize website content, as well as computer programs, web browsers, and apps in general. Plugins can accomplish this without significantly increasing resource use or compelling primary software developers to offer ongoing plugin support.
Examples of applications that use plugins include video game console emulators, graphics software, text editors, and integrated development environments). Plugins can be used to support file formats, process images, support programming languages, and enhance the development process).
Plugins are invaluable tools for webmasters and site visitors alike. They can add entirely new dimensions to a website, improving its capabilities. Every web browser has an official website where you can download and install plugins (also called "add-ons" or "extensions"). The web browser publisher verifies the plugins are not harmful before making them available to download.

They are used in a variety of applications, including video game console emulators, graphics software, text editors, and integrated development environments.
