A simple, multi-size ICO converter

An .ico file bundles multiple resolutions so a single favicon works everywhere. This converter takes a PNG, JPG, WebP, or SVG and writes a favicon.ico containing 16, 32, and 48 px, right in your browser — no desktop software needed.

Because the format also matters for sharing the whole favicon set, the zip includes PNG icons up to 512 px, an apple-touch-icon, Android icons, and a site.webmanifest alongside the .ico.

How to make a favicon.ico

  1. Add an image — drag & drop, paste, or pick a PNG, JPG, WebP, or SVG.
  2. Choose the background — transparent for tabs, or a solid color for a filled icon.
  3. Add padding if needed — a small margin keeps art clear of rounded corners.
  4. Download — the favicon.ico and the rest of the set come in one zip.

Tip: one .ico, every browser

Place favicon.ico at the root of your domain and reference it with a single link tag. Older browsers find it automatically; modern ones use the PNG and manifest icons you also get here.

favicon.ico: sizes and where each is used

Le format .ico regroupe plusieurs résolutions pour qu'un seul favicon fonctionne partout, d'Internet Explorer au Chrome le plus récent. Toute image que vous convertissez est écrite dans un unique favicon.ico contenant ces tailles :

Size File Where it's used
16 × 16 px inside favicon.ico L'icône courante de l'onglet et de la barre d'adresse en densité 1×.
32 × 32 px inside favicon.ico L'icône Retina de l'onglet et du favori, et le raccourci Windows.
48 × 48 px inside favicon.ico L'entrée plus grande que les contextes du bureau et de Windows peuvent sélectionner.

Format & container

Un véritable en-tête ICONDIR pointe vers chaque taille encodée en PNG, ainsi le navigateur lit un seul fichier et choisit la résolution la plus nette selon le contexte — sans fichiers petits et grands séparés pour la compatibilité ancienne.

How it's wired into your page

                <link rel="icon" href="/favicon.ico" sizes="any">
<!-- placez favicon.ico à la racine du domaine ; les anciens navigateurs le trouvent d'eux-mêmes -->
              

Tip

Déposez favicon.ico à la racine de votre domaine (ex. example.com/favicon.ico) : les navigateurs demandent ce chemin par défaut, même sans balise link, ce qui explique pourquoi le repli ancien fonctionne encore.
