PNG to ICO

Convert a PNG to a multi-size ICO in your browser. Your PNG becomes a favicon.ico with 16, 32, and 48 px — plus the rest of a favicon set.

Turn a PNG into a real .ico

The .ico format can hold several sizes in one file, which is exactly what a favicon needs. Drop a PNG here and it is downscaled to 16, 32, and 48 px and packed into a single favicon.ico — the format Windows and older browsers expect.

You also get standalone PNG icons, an apple-touch-icon, Android icons, and a manifest in the same zip, so one PNG gives you everything required to add a favicon to a website. Conversion runs entirely on your device.

How to convert PNG to ICO

  1. Add your PNG — drag & drop, paste, or choose a file (JPG, WebP, and SVG work too).
  2. Set the background — keep transparency or add a solid color if your PNG has fine detail.
  3. Check the previews — confirm the 16 and 32 px versions stay readable.
  4. Download the zip — your favicon.ico is inside, ready to drop at your site root.

Tip: keep PNG transparency

If your PNG has a transparent background, leave it transparent so the icon blends into light and dark browser tabs. Only add a color if thin lines vanish on certain themes.

el contenedor .ico: sizes and where each is used

Un archivo .ico es un contenedor de iconos que puede albergar varios mapas de bits en un solo archivo, que es justo lo que necesita un favicon. Tu PNG se reduce y se empaqueta en un único favicon.ico con estos tamaños:

Size File Where it's used
16 × 16 px inside favicon.ico El icono de la pestaña del navegador y de la barra de direcciones con densidad de pantalla estándar.
32 × 32 px inside favicon.ico El icono de la pestaña y del marcador en pantallas de alta densidad y la barra de tareas de Windows.
48 × 48 px inside favicon.ico La entrada de mayor tamaño que pueden elegir los accesos directos de escritorio y los mosaicos de Windows.

Format & container

Cada tamaño dentro del .ico se almacena como una entrada codificada en PNG sin pérdidas, por lo que el contenedor en sí no provoca pérdida de calidad; solo el detalle de tu arte de origen limita lo nítido que se ve el icono pequeño.

How it's wired into your page

                <link rel="icon" href="/favicon.ico" sizes="any">
<!-- favicon.ico también se encuentra automáticamente en la raíz de tu sitio -->
              

Tip

Conserva la transparencia del PNG en el origen para que el icono se integre tanto en pestañas claras como oscuras del navegador; añade un color de fondo sólido solo si las líneas finas desaparecen contra uno de los temas.

Preguntas frecuentes

Is the .ico a true multi-size icon?

Yes. The favicon.ico contains 16, 32, and 48 px in one file, so the browser can pick the crispest size for each context.

Can I convert JPG or WebP to ICO instead?

Yes — the converter accepts PNG, JPG, WebP, and SVG. For the sharpest small icon, start from the highest-resolution source you have.

Where does the conversion happen?

In your browser, so the .ico is created on your own device. How any data associated with the tool is handled is described in our privacy policy.

Does converting reduce quality?

Icons are tiny, so downscaling a larger PNG actually improves sharpness. The .ico is lossless; the only thing that affects clarity is how detailed your source art is.
