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

El formato .ico agrupa varias resoluciones para que un solo favicon funcione en todas partes, desde Internet Explorer hasta el Chrome más reciente. Cualquier imagen que conviertas se escribe en un único favicon.ico con estos tamaños:

Size File Where it's used
16 × 16 px inside favicon.ico El icono cotidiano de la pestaña y de la barra de direcciones a densidad 1×.
32 × 32 px inside favicon.ico El icono Retina de la pestaña y del marcador, y el acceso directo de Windows.
48 × 48 px inside favicon.ico La entrada mayor que pueden seleccionar los contextos de escritorio y de Windows.

Format & container

Una cabecera ICONDIR real apunta a cada tamaño codificado en PNG, así que el navegador lee un solo archivo y elige la resolución más nítida para el contexto, sin necesidad de archivos pequeños y grandes separados para la compatibilidad heredada.

How it's wired into your page

                <link rel="icon" href="/favicon.ico" sizes="any">
<!-- coloca favicon.ico en la raíz del dominio; los navegadores antiguos lo encuentran solos -->
              

Tip

Coloca favicon.ico en la raíz de tu dominio (p. ej. example.com/favicon.ico): los navegadores solicitan esa ruta por defecto incluso sin una etiqueta link, por eso el respaldo heredado sigue funcionando.
