Warning

The warning icon represents a cautionary signal used to alert users of potential danger or risk. It is commonly used in digital interfaces to draw attention to critical information.

The warning icon is often used in software applications, websites, and mobile apps to indicate potential threats or hazards. It is also used in safety and security-related contexts.

From a UX perspective, the warning icon communicates a sense of caution and urgency. When used in digital interfaces, it can help users quickly identify potential risks and take necessary actions.

Warning is one of 2,162 icons in Noto Emoji (v1), made by Google Inc and released under Apache 2.0. It is drawn on a 128 × 128 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 WarningIcon to components/icons/noto-v1-warning.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 WarningIcon 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 Warning icon, or any of 2,162 Noto Emoji (v1) icons, and install it from a prompt.

It's multicolor, so it keeps its own colors.

Set width and height on the component, or a class like size-6. It's drawn on a 128 × 128 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It keeps its own colors in light and dark mode, so check it against both backgrounds. 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="Warning", so screen readers say what it does.

Yes. WarningIcon passes every SVG prop to the svg element, so <WarningIcon 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. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Noto Emoji (v1), Google Inc and the license.

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