About Fluent UI System Icons

How to use Fluent UI System Icons icons

The fastest way is to embed an icon as an <img> from the Iconify CDN — no install, no build step, no JavaScript required.

Inline HTML

<img src="https://api.iconify.design/fluent/zoom-out-24-filled.svg" width="24" height="24" alt="zoom-out-24-filled icon" />

CSS background

.icon-zoom-out-24-filled {
  background: url('https://api.iconify.design/fluent/zoom-out-24-filled.svg') center / contain no-repeat;
  width: 24px;
  height: 24px;
}

React (with @iconify/react)

import { Icon } from '@iconify/react';

<Icon icon="fluent:zoom-out-24-filled" width="24" />

Recolouring Fluent UI System Icons icons

Fluent UI System Icons icons use currentColor, so changing colour is a one-line CSS rule. Set color on the parent element and the icon adopts it. This makes the set easy to theme for light mode, dark mode, and brand colour accents.

Search engine–safe usage

Always include a meaningful alt attribute on <img> tags or an aria-label on inline SVGs. For purely decorative icons (where text already conveys the meaning), use alt="" so screen readers skip them.

License & attribution

Fluent UI System Icons is distributed under the MIT license. Read the full terms at the official license page. Most permissive licenses (MIT, Apache 2.0, CC0) don’t require attribution in shipped binaries, but it’s considered good practice to credit the icon set in your project’s docs or about page.
