Comment ajouter des favicons

Comment ajouter des favicons à un projet, selon le framework. Guide d’installation pas à pas, avec exemples pour HTML, Next.js, Nuxt.js, React, Vue.js et SvelteKit.

Avant de commencer

Concevez d’abord le favicon sur la page d’accueil et téléchargez le ZIP complet. Il contient toutes les tailles nécessaires.

Après le téléchargement, décompressez le ZIP. Placez ensuite les fichiers dans le dossier public du projet (static pour SvelteKit, ou la racine pour du HTML pur).

Une fois les fichiers en place, suivez les instructions ci-dessous pour ajouter les liens HTML selon le framework.

Guides d’installation par framework

Pure HTML

Placez tous les fichiers de favicon à la racine du site (ou dans public si vous utilisez un générateur de site statique), puis ajoutez les liens suivants dans le head du fichier HTML :

<link rel="icon" type="image/x-icon" sizes="16x16 32x32 48x48" href="/favicon.ico">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="48x48" href="/favicon-48x48.png">
<link rel="icon" type="image/png" sizes="96x96" href="/favicon-96x96.png">
<link rel="icon" type="image/png" sizes="180x180" href="/favicon-180x180.png">
<link rel="icon" type="image/png" sizes="192x192" href="/favicon-192x192.png">
<link rel="icon" type="image/png" sizes="512x512" href="/favicon-512x512.png">
<link rel="icon" type="image/svg+xml" href="/favicon.svg">

Next.js

Placez tous les fichiers dans le dossier public, puis ajoutez les métadonnées dans app/layout.tsx ou pages/_document.tsx :

// app/layout.tsx (App Router)
import type { Metadata } from 'next'

export const metadata: Metadata = {
  icons: {
    icon: [
      { url: '/favicon.ico', sizes: '16x16 32x32 48x48' },
      { url: '/favicon-16x16.png', sizes: '16x16', type: 'image/png' },
      { url: '/favicon-32x32.png', sizes: '32x32', type: 'image/png' },
      { url: '/favicon-48x48.png', sizes: '48x48', type: 'image/png' },
      { url: '/favicon-96x96.png', sizes: '96x96', type: 'image/png' },
      { url: '/favicon-180x180.png', sizes: '180x180', type: 'image/png' },
      { url: '/favicon-192x192.png', sizes: '192x192', type: 'image/png' },
      { url: '/favicon-512x512.png', sizes: '512x512', type: 'image/png' },
      { url: '/favicon.svg', type: 'image/svg+xml' },
    ],
    apple: [
      { url: '/apple-touch-icon.png', sizes: '180x180', type: 'image/png' },
    ],
  },
}

Ou utilisez le composant next/head dans le Pages Router :

// pages/_document.tsx (Pages Router)
import Head from 'next/head'

export default function Document() {
  return (
    <Head>
      <link rel="icon" type="image/x-icon" href="/favicon.ico" />
      <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png" />
      <link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png" />
      <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" />
      <link rel="icon" type="image/png" sizes="48x48" href="/favicon-48x48.png" />
      <link rel="icon" type="image/png" sizes="96x96" href="/favicon-96x96.png" />
      <link rel="icon" type="image/png" sizes="180x180" href="/favicon-180x180.png" />
      <link rel="icon" type="image/png" sizes="192x192" href="/favicon-192x192.png" />
      <link rel="icon" type="image/png" sizes="512x512" href="/favicon-512x512.png" />
      <link rel="icon" type="image/svg+xml" href="/favicon.svg" />
    </Head>
  )
}

Nuxt.js

Placez tous les fichiers dans le dossier public, puis configurez dans nuxt.config.ts ou app.vue :

// nuxt.config.ts
export default defineNuxtConfig({
  app: {
    head: {
      link: [
        { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' },
        { rel: 'apple-touch-icon', sizes: '180x180', href: '/apple-touch-icon.png' },
        { rel: 'icon', type: 'image/png', sizes: '16x16', href: '/favicon-16x16.png' },
        { rel: 'icon', type: 'image/png', sizes: '32x32', href: '/favicon-32x32.png' },
        { rel: 'icon', type: 'image/png', sizes: '48x48', href: '/favicon-48x48.png' },
        { rel: 'icon', type: 'image/png', sizes: '96x96', href: '/favicon-96x96.png' },
        { rel: 'icon', type: 'image/png', sizes: '180x180', href: '/favicon-180x180.png' },
        { rel: 'icon', type: 'image/png', sizes: '192x192', href: '/favicon-192x192.png' },
        { rel: 'icon', type: 'image/png', sizes: '512x512', href: '/favicon-512x512.png' },
        { rel: 'icon', type: 'image/svg+xml', href: '/favicon.svg' },
      ],
    },
  },
})

Ou utilisez useHead dans app.vue :

// app.vue
<script setup>
useHead({
  link: [
    { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' },
    { rel: 'apple-touch-icon', sizes: '180x180', href: '/apple-touch-icon.png' },
    { rel: 'icon', type: 'image/png', sizes: '16x16', href: '/favicon-16x16.png' },
    { rel: 'icon', type: 'image/png', sizes: '32x32', href: '/favicon-32x32.png' },
    { rel: 'icon', type: 'image/png', sizes: '48x48', href: '/favicon-48x48.png' },
    { rel: 'icon', type: 'image/png', sizes: '96x96', href: '/favicon-96x96.png' },
    { rel: 'icon', type: 'image/png', sizes: '180x180', href: '/favicon-180x180.png' },
    { rel: 'icon', type: 'image/png', sizes: '192x192', href: '/favicon-192x192.png' },
    { rel: 'icon', type: 'image/png', sizes: '512x512', href: '/favicon-512x512.png' },
    { rel: 'icon', type: 'image/svg+xml', href: '/favicon.svg' },
  ],
})
</script>
