Extension

The extension icon represents an add-on or a plugin that can be used to extend the functionality of a software or platform. It is commonly depicted as a puzzle piece or a gear with additional components. This symbol originates from the context of software development and modular design.

The extension icon appears in various software and platforms, such as browser stores, where users can find and install extensions to enhance their browsing experience. It is also used in digital design tools like Visual Studio Code, where extensions can be installed to provide additional features.

From a UX perspective, the extension icon communicates the idea of adding new functionality or capabilities to a software or platform. It helps users understand that they can customize and extend the behavior of the application.

Extension is one of 665 icons in BoxIcons Solid, made by Atisa and released under CC BY 4.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds ExtensionIcon to components/icons/bxs-extension.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed ExtensionIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Extension icon, or any of 665 BoxIcons Solid icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Extension", so screen readers say what it does.

Yes. ExtensionIcon passes every SVG prop to the svg element, so <ExtensionIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with credit: CC BY 4.0 asks you to credit the author (Atisa) where you use the icons. The full terms are in the license, linked on this page.

Yes. CC BY 4.0 asks you to credit the author where you use the icons, for example "Icons by Atisa, CC BY 4.0" on an about or credits page.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
