As part of a major update, we will be replacing the existing phosphor-react package with @phosphor-icons/react. We recommend using this new version, as it has improved performance and a significantly smaller bundle size. No APIs have been changed, so drop-in replacement should be straightforward. The legacy package will continue to receive maintenance, but will not be updated with new icons upstream. Take me to the legacy version ➜


Phosphor is a flexible icon family for interfaces, diagrams, presentations — whatever, really. Explore all our icons at

Simply import the icons you need, and add them anywhere in your render method. Phosphor supports tree-shaking, so your bundle only includes code for the icons you use.

import { Horse, Heart, Cube } from "@phosphor-icons/react";

const App = () => {
  return (
      <Horse />
      <Heart color="#AE2983" weight="fill" size={32} />
      <Cube color="teal" weight="duotone" />

React Server Components and SSR

When using Phosphor Icons in an SSR environment, within a React Server Component, or in any environment that does not permit the use of the Context API (Next.js Server Component, for example), import icons from the /dist/ssr submodule:

import { Fish } from "@phosphor-icons/react/dist/ssr";

const MyServerComponent = () => {
  return <Fish weight="duotone" />;


These variants do not use React Context, and thus cannot inherit styles from an ancestor IconContext.


Icon components accept all props that you can pass to a normal SVG element, including inline style objects, onClick handlers, and more. The main way of styling them will usually be with the following props:

  • color?: string – Icon stroke/fill color. Can be any CSS color string, including hex, rgb, rgba, hsl, hsla, named colors, or the special currentColor variable.
  • size?: number | string – Icon height & width. As with standard React elements, this can be a number, or a string with units in px, %, em, rem, pt, cm, mm, in.
  • weight?: "thin" | "light" | "regular" | "bold" | "fill" | "duotone" – Icon weight/style. Can also be used, for example, to "toggle" an icon's state: a rating component could use Stars with weight="regular" to denote an empty star, and weight="fill" to denote a filled star.
  • mirrored?: boolean – Flip the icon horizontally. Can be useful in RTL languages where normal icon orientation is not appropriate.
  • alt?: string – Add accessible alt text to an icon.


Phosphor takes advantage of React Context to make applying a default style to all icons simple. Create an IconContext.Provider at the root of the app (or anywhere above the icons in the tree) and pass in a configuration object with props to be applied by default to all icons:

import { IconContext, Horse, Heart, Cube } from "@phosphor-icons/react";

const App = () => {
  return (
        color: "limegreen",
        size: 32,
        weight: "bold",
        mirrored: false,
        <Horse /> {/* I'm lime-green, 32px, and bold! */}
        <Heart /> {/* Me too! */}
        <Cube /> {/* Me three :) */}

You may create multiple Contexts for styling icons differently in separate regions of an application; icons use the nearest Context above them to determine their style.


The context will also pass any provided SVG props down to icon instances, which can be useful E.G. in adding accessible aria-labels, classNames, etc.


React Context is not available in some environments. See React Server Components and SSR for details.


Components can accept arbitrary SVG elements as children, so long as they are valid children of the <svg> element. This can be used to modify an icon with background layers or shapes, filters, animations, and more. The children will be placed below the normal icon contents.

The following will cause the Cube icon to rotate and pulse:

const RotatingCube = () => {
  return (
    <Cube color="darkorchid" weight="duotone">
        from="0 0 0"
        to="360 0 0"


The coordinate space of slotted elements is relative to the contents of the icon viewBox, which is 256x256 square. Only valid SVG elements will be rendered.


You may wish to import all icons at once for use in your project, though depending on your bundler this could prevent tree-shaking and make your app's bundle larger.

import * as Icon from "@phosphor-icons/react";

<Icon.Smiley />
<Icon.Folder weight="thin" />
<Icon.BatteryHalf size="24px" />

Custom Icons

It is possible to extend Phosphor with your custom icons, taking advantage of the styling and context abstractions used in our library. To create a custom icon, first design your icons on a 256x256 pixel grid, and export them as SVG. For best results, flatten the icon so that you only export assets with path elements. Strip any fill or stroke attributes, as these will be inherited from the wrapper.

Next, create a new React forwardRef component, importing the IconBase component, as well as the Icon and IconWeight types from this library. Define a Map<IconWeight, ReactElement> that maps each icon weight to the contents of each SVG asset, effectively removing the wrapping <svg> element from each. Name your component, and render an <IconBase />, passing all props and the ref, as well as the weights you defined earlier, as JSX props:

import { forwardRef, ReactElement } from "react";
import { Icon, IconBase, IconWeight } from "@phosphor-icons/react";

const weights = new Map<IconWeight, ReactElement>([
  ["thin", <path d="..." />],
  ["light", <path d="..." />],
  ["regular", <path d="..." />],
  ["bold", <path d="..." />],
  ["fill", <path d="..." />],
      <path d="..." opacity="0.2" />
      <path d="..." />

const CustomIcon: Icon = forwardRef((props, ref) => (
  <IconBase ref={ref} {...props} weights={weights} />

CustomIcon.displayName = "CustomIcon";

export default CustomIcon;


If you have multiple child elements, wrap them in a Fragment. Typically our duotone icons have multiple elements, with the background layer at 20% opacity.

If Custom Icons are intended to be used in React Server Components, use <SSRBase /> instead of <IconBase /> as the render component.
