Icon

The QIcon component allows you to easily insert icons within other components or any other area of your pages. Quasar supports out of the box: Material Icons , Material Symbols , Font Awesome, Ionicons, MDI, Eva Icons, Themify Icons, Line Awesome and Bootstrap Icons.

Furthermore you can add support by yourself for any icon lib.

There are multiple types of icons in Quasar: webfont-based, svg-based and image-based. You are not bound to using only one type in your website/app.

Size & colors

The sizing of a QIcon is manipulated by the font-size CSS property. Also, QIcon inherits the current CSS text color used. For ease of use there are the QIcon size and color props.

Basic



For icon properties on different Quasar components you won’t have the means to specify an icon for each platform, but you can achieve the same effect with:

<q-btn
  :icon="$q.platform.is.ios ? 'settings' : 'ion-ios-gear-outline'"
/>
Standard sizes



Webfont icons

WARNING

If you are using webfont-based icons, make sure that you installed the icon library that you are using, otherwise it won’t show up!

Naming convention

Material Icons (Google)

  • Icon names are always in snake_case.
  • Go to Material Icons and Symbols, look for your desired icon. Remember its name (eg. “all_inbox”) and use it.

MDI (Material Design Icons)

  • Icon names are in hyphen-separated case and always begin with “mdi-” prefix.
  • Go to MDI, look for your desired icon, click on it. A dialog box will appear. Get the title (eg. “account-key”), prefix it with “mdi-” and you get the result (eg. “mdi-account-key”).

Fontawesome

  • Icon names are in hyphen-serapated case and always begin with “fas fa-”, “fab fa-”, “fal fa-” or “far fa-” prefixes.
  • Newer versions also have fa-solid, fa-brands, fa-light or fa-regular (pro also has fa-thin, fa-duotone)
  • Go to FontAwesome, look for your desired icon, click on it. You’ll get to its page. Below the icon name (as title), you will see something like <i class="fa-solid fa-flag"></i>. The result is fa-solid fa-flag (you can also use fas fa-flag).
  • Note: fas, far, fab, fal, fat and fad are deprecated and may not be available in future major versions).

Ionicons

  • Icon names are in hyphen-separated case and always begin with “ion-”, “ion-md-”, “ion-ios-” or “ion-logo-” prefixes.
  • Go to Ionicons (v6) or Ionicons (v4), look for your desired icon, click on it. At the bottom of the page there will appear a popup. Notice something like <ion-icon name="square-outline"></ion-icon>. Remember the name (eg. “square-outline”). Based on the variant that you want (auto-detect platform, material or iOS), you’d get the result: ion-square-outline or ion-md-square-outline or ion-ios-square-outline.
  • Note: Starting with v5, Ionicons no longer supplies a webfont. Also,they no longer do Material or IOS variants.

Eva Icons

  • Icon names are in hyphen-separated case and always begin with “eva-” prefix.
  • Go to Eva Icons, look for your desired icon, click on it. A dialog box will appear. Get the name from there (eg. “attach-outline”), prefix it with “eva” and the result is “eva-attach-outline”.

Themify

  • Icon names are in hyphen-separated case and always begin with “ti-” prefix.
  • Go to Themify, look for your desired icon. Remember its name (eg. “ti-arrow-top-right”) and use it.

Line Awesome

  • Icon names are in hyphen-separated case and always begin with “la” prefix.
  • Go to Line Awesome, look for your desired icon, click on it. A dialog box will appear. You’ll see something like <i class="lab la-behance-square"></i>. Remember its name (eg. “lab la-behance-square”) and use it.

Bootstrap Icons

  • Icon names are in hyphen-separated case and always begin with “bi-” prefix.
  • Go to Bootstrap Icons, look for your desired icon. Remember its name (eg. “bi-bug-fill”) and use it.

Svg icons

There are many advantages of using only svg icons in your website/app:

  • Better app footprint – only used icons will be included in the final build (treeshaking in action)
  • Better quality icons
  • No need for including equivalent webfonts from @quasar/extras or CDN.

The current disadvantage is that it is more tedious to use these icons than their webfont counterpart.

Svg usage

Usage inside the <template>:

<template>
  <div>
    <q-icon :name="matMenu" />
    <q-icon :name="fasFont" />
    <q-btn :icon="mdiAbTesting" />
  </div>
</template>

Notice that we are using : to bind variables instead of plain values, it’s important. We must make those variables available to the template. The way to do that depends on your Vue API preference:

Composition API with “script setup”

This is the most convenient way. Just importing the variables is enough to make them available to the template.

<script setup>
import { matMenu } from '@quasar/extras/material-icons'
import { mdiAbTesting } from '@quasar/extras/mdi-v6'
import { fasFont } from '@quasar/extras/fontawesome-v5'
</script>

Composition API without “script setup”

<script>
import { matMenu } from '@quasar/extras/material-icons'
import { mdiAbTesting } from '@quasar/extras/mdi-v6'
import { fasFont } from '@quasar/extras/fontawesome-v5'

export default {
  // ...
  setup () {
    return {
      matMenu,
      mdiAbTesting,
      fasFont
    }
  }
}
</script>

Options API

Notice in the example below that we are injecting the icons through the created() hook instead of returning them from data(). That is because we want to avoid Vue from making them reactive. Since they are static values, making them reactive would introduce some unnecessary overhead. It would still work if we declare them in data(), but it would be less performant.

<script>
import { matMenu } from '@quasar/extras/material-icons'
import { mdiAbTesting } from '@quasar/extras/mdi-v6'
import { fasFont } from '@quasar/extras/fontawesome-v5'

export default {
  // ...
  created () {
    this.matMenu = matMenu
    this.mdiAbTesting = mdiAbTesting
    this.fasFont = fasFont
  }
}
</script>

TIP

If you are only using svg icons (and have configured a Quasar Icon Set) then you don’t need the webfont equivalent in your app at all.

Import guide

Svg icons are supplied by @quasar/extras (although you can supply your own svg icons too!). Here’s the ins and outs of the import syntax:

SVG Material Icons (Google)

  • Icon names are in camel-case and always begin with “mat” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “mat” and camel-case the result (eg. “matAllInbox”).
  • Import statement example: import { matAllInbox } from '@quasar/extras/material-icons'.

SVG Material Icons Outlined (Google)

  • Icon names are in camel-case and always begin with “outlined” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “outlined” and camel-case the result (eg. “outlinedAllInbox”).
  • Import statement example: import { outlinedAllInbox } from '@quasar/extras/material-icons-outlined'.

SVG Material Icons Sharp (Google)

  • Icon names are in camel-case and always begin with “sharp” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “sharp” and camel-case the result (eg. “sharpAllInbox”).
  • Import statement example: import { sharpAllInbox } from '@quasar/extras/material-icons-sharp'.

SVG Material Icons Round (Google)

  • Icon names are in camel-case and always begin with “round” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “round” and camel-case the result (eg. “roundAllInbox”).
  • Import statement example: import { roundAllInbox } from '@quasar/extras/material-icons-round'.

SVG Material Symbols Outlined (Google)

SVG Material Symbols Sharp (Google)

  • Icon names are in camel-case and always begin with “symSharp” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “symSharp” and camel-case the result (eg. “symSharpAllInbox”).
  • Import statement example: import { symSharpAllInbox } from '@quasar/extras/material-symbols-sharp'.

SVG Material Symbols Rounded (Google)

  • Icon names are in camel-case and always begin with “symRounded” prefix.
  • Go to Material Icons, look for your desired icon and remember its name (eg. “all_inbox”), prefix it with “symRounded” and camel-case the result (eg. “symRoundedAllInbox”).
  • Import statement example: import { symRoundedAllInbox } from '@quasar/extras/material-symbols-rounded'.

SVG MDI (Material Design Icons)

  • Icon names are in camel-case and always begin with “mdi” prefix.

  • Import statement example: import { mdiAccountKey } from '@quasar/extras/mdi-v6'.

SVG Fontawesome

  • Icon names are in camel-case and always begin with “fas”, “fab”, “fal” or “far” prefixes.
  • Go to FontAwesome, look for your desired icon, click on it. You’ll get to its page. Below the icon name (as title), you will see something like <i class="fas fa-flag"></i>. This would translate to fasFlag. The prefix from the tag is important.
  • Note that we cannot supply the “Pro” version of the icons in svg format because of the license.
  • Import statement example: import { fasFlag } from '@quasar/extras/fontawesome-v6'.
  • The Quasar SVG form is still using fas, far and fab, instead of the newer fa-solid, fa-regular and fa-brands.

SVG Ionicons

  • Ionicons v4: Icon names are in camel-case and always begin with “ionMd” or “ionIos” prefixes.
  • Ionicons v5/v6: Icon names are in camel-case and always begin with “ion” prefix.

  • Import statement example: import { evaAttachOutline } from '@quasar/extras/eva-icons'.

SVG Themify

  • Icon names are in camel-case and always begin with “ti” prefix.
  • Go to Themify, look for your desired icon. Remember its name (eg. “ti-arrow-top-right”), prefix it with “ti” and camel-case the result (eg. “tiArrowTopRight”).
  • Import statement example: import { tiArrowTopRight } from '@quasar/extras/themify'.

There is a special case though (only for solid icons!): if the prefix before “la-” is “las” (eg. <i class="las la-atom"></i>), then you need to suffix “la-atom” with “-solid” and camel-case the result (eg. laAtomSolid).
  • Import statement example: import { laBehanceSquare } from '@quasar/extras/line-awesome'.

SVG Bootstrap Icons

  • Icon names are in camel-case and always begin with “bi” prefix.
  • Go to Bootstrap Icons, look for your desired icon. Remember its name (eg. “bi-bug-fill”), camel-case the result (eg. “biBugFill”).
  • Import statement example: import { biBugFill } from '@quasar/extras/bootstrap-icons'.

Svg icon format

You can also supply your own svg icons. An svg icon is essentially a String with the following syntax:

Syntax: "<path>&&<path>&&...|<viewBox>"
           P       P             V
                (optional)   (optional)
                             (default: 0 0 24 24)

P is a path tag with following syntax (each are attributes):
        "<d>@@<style>@@<transform>"
        (required)
            (optional)
                     (optional)

SVG-use way

This svg method allows you to store the SVG files as static assets and reference them.

// File: /public/icons.svg

<svg xmlns="http://www.w3.org/2000/svg">
  <symbol id="icon-1" viewBox="0 0 24 24">
    <path d="..."></path>
  </symbol>
  <symbol id="icon-2" viewBox="0 0 24 24">
     <path d="..."></path>
  </symbol>
</svg>

The standard HTML way is to include the file and specify the icon with the svg use tag.

<svg>
  <use xlink:href="icons.svg#icon-1"></use>
</svg>

To use this with Quasar through QIcon (make sure that you are referencing the correct file from your public folder):

<q-icon name="svguse:icons.svg#icon-1">
<!-- or -->
<q-btn-dropdown label="Custom Content" dropdown-icon="svguse:icons.svg#icon-2" />

By default, the parent svg’s viewBox is “0 0 24 24”. However, you can also specify a custom one:

<q-icon name="svguse:icons.svg#icon-1|10 15 40 40" />

Inlined svg

If you don’t want to use the webfont or svg variants from above, note that QIcon also supports one inlined <svg> tag (the content of the svg can be anything, not only a path).

Reasoning on why to use an <svg> in a QIcon is that the svg will respect the size and color as any QIcon through its props. Without these features, you’re better off inlining the svg in your templates without wrapping with QIcon.

<q-icon color="accent" size="5rem">
  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
    <path d="M0 0h24v24H0z" fill="none"/>
    <path d="M19 3h-4.18C14.4 1.84 13.3 1 12 1c-1.3 0-2.4.84-2.82 2H5c-1.1 0-2 .9-2 2v14c0 1.1.9 2 2 2h14c1.1 0 2-.9 2-2V5c0-1.1-.9-2-2-2zm-7 0c.55 0 1 .45 1 1s-.45 1-1 1-1-.45-1-1 .45-1 1-1zm0 4c1.66 0 3 1.34 3 3s-1.34 3-3 3-3-1.34-3-3 1.34-3 3-3zm6 12H6v-1.4c0-2 4-3.1 6-3.1s6 1.1 6 3.1V19z"/>
  </svg>
</q-icon>

Some limitations:

  • do not use “height”/“width” attributes on the <svg> tag (it will break QIcon’s way of handling the size)
  • all <path>s will have “fill: currentColor” CSS applied by default; if you don’t want that, then add fill="none" to the <path> tag

Image icons

You can also make an icon point to an image URL instead of relying on any webfont, by using the img: prefix.

All icon related props of Quasar components can make use of this.

<q-icon name="img:https://cdn.quasar.dev/logo-v2/svg/logo.svg" />
<q-btn icon="img:https://cdn.quasar.dev/logo-v2/svg/logo.svg" ... />

<!-- reference from /public: -->
<q-icon name="img:my/path/to/some.svg" />

TIP

Remember that you can place images in your /public folder too and point to them. You don’t always need a full URL.

This is not restricted to SVG only. You can use whatever image type you want (png, jpg, …):

<q-icon name="img:bla/bla/my.png" />
<q-btn icon="img:bla/bla/my.jpg" ... />
<q-input clearable clear-icon="img:bla/bla/my.gif" ... />

It is also possible to inline the image (svg, png, jpeg, gif…) and dynamically change its style (svg):

<q-icon name="img:data:image/svg+xml;charset=utf8,<svg xmlns='http://www.w3.org/2000/svg' height='140' width='500'><ellipse cx='200' cy='80' rx='100' ry='50' style='fill:yellow;stroke:purple;stroke-width:2' /></svg>" />
Dynamic SVG



You can also base64 encode an image and supply it. The example below is with a QBtn, but the same principle is involved when dealing with any icon prop or with QIcon:

<q-btn icon="
img:data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" ... />

Custom mapping

Should you want, you can customize the mapping of icon names. This can be done by providing a custom icon map function. There are several ways to provide one:

  • Set Quasar.iconSet.iconMapFn in an entry file:
    • In a boot file if using Quasar CLI (with Vite or Webpack)
    • In main.js/main.ts(or similar) if using Vite plugin and Vue CLI
    • In any suitable file or script tag if using UMD
  • Set $q.iconMapFn in the root component, e.g. App.vue:
    • At the top-level if using Composition API with <script setup>
    • In the setup() function if using Composition API
    • In the created() hook if using Options API
  • Set iconMapFn in Quasar Vue plugin options, e.g. app.use(Quasar, { iconMapFn: () => { /* ... */ } }) (for flavours other than Quasar CLI).

We will use the $q.iconMapFn approach using <script setup> in the use case examples below, but the same principle applies to the other methods.

The structure of iconMapFn is as follows:

type GlobalQuasarIconMapFn = (
  iconName: string
) =>
  // Map to another existing icon
  {
    icon: string  // the mapped icon string, which will be handled
                  // by Quasar as if the original QIcon name was this value
  } |
  // Define how to interpret the icon
  {
    cls: string;     // class name(s)
    content?: string // optional, in case you are using a ligature font
                     // and you need it as content of the QIcon
  } |
  // Leave it as is, default Quasar handling
  void;

Mapping icons will not only affect QIcon, but also any other Quasar component that uses icons like QBtn, QInput, and more.

Use case 1: Simply mapping a few icons

import { useQuasar } from 'quasar'

const myIcons = {
  'app:icon1': 'img:/path/to/icon1.svg',
  'app:icon2': 'img:/path/to/icon2.svg',
  'app:copy': 'fas fa-copy',
}

// ...
const $q = useQuasar()

$q.iconMapFn = (iconName) => {
  const icon = myIcons[iconName]
  if (icon !== undefined) {
    return { icon }
  }
}

Now we can use <q-icon name="app:copy" /> or <q-icon name="app:icon1" /> and QIcon will treat “app:copy” and “app:icon1” as if they were written as “fas fa-copy” and “img:/path/to/icon1.svg”. The same applies to any other Quasar component that uses icons, e.g. <q-btn icon="app:copy" />.

Use case 2: Support for custom icon library

This is especially useful when you are using a custom icon library (that doesn’t come with Quasar and its @quasar/extras package).

import { useQuasar } from 'quasar'

const $q = useQuasar()

// Example of adding support for `<q-icon name="app:...." />`
// This includes support for all "icon" props of Quasar components

$q.iconMapFn = (iconName) => {
  // iconName is the content of QIcon "name" prop (or related icon prop of other Quasar components)

  // can be any logic you want, but for this example:
  if (iconName.startsWith('app:') === true) {
    // we strip the "app:" part
    const name = iconName.substring(4)

    return {
      cls: 'my-app-icon ' + name
    }
  }

  // when we don't return anything from our iconMapFn,
  // the default Quasar icon mapping takes over
}

Notice in the examples above that we are returning a my-app-icon class that gets applied to QIcon if our icon starts with app: prefix. We can use it to define how QIcon should react to it, from a CSS point of view.

Let’s assume we have our own webfont called “My App Icon”.

/*
  For this example, we are creating:
  /src/css/my-app-icon.css
*/

.my-app-icon {
  font-family: 'My App Icon';
  font-weight: 400;
}

@font-face {
  font-family: 'My App Icon';
  font-style: normal; /* whatever is required for your */
  font-weight: 400;   /* webfont.... */
  src: url("./my-app-icon.woff2") format("woff2"), url("./my-app-icon.woff") format("woff");
}

We should then add the newly created CSS file into our app:

  • Quasar CLI: Add it to the css array in quasar.config file

    // quasar.config file
    css: [
      // ....
      'my-app-icon.css'
    ]
  • Other: Add it to your CSS file, import it in your main.js/main.ts or include it in your HTML file:

    // in your main.js/main.ts
    import 'src/css/my-app-icon.css'
    
    // or in the main css file
    @import url('./my-app-icon.css');
    
    // or in your HTML file (UMD)
    <link rel="stylesheet" href="/css/my-app-icon.css">

And also add “my-app-icon.woff2” and “my-app-icon.woff” files into the same folder as “my-app-icon.css” (or somewhere else, but edit the relative paths (see “src:” above) to the woff/woff2 files).
