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.

der .ico-Container: sizes and where each is used

Eine .ico-Datei ist ein Symbol-Container, der mehrere Bitmaps in einer Datei aufnehmen kann — genau das, was ein Favicon braucht. Ihr PNG wird herunterskaliert und in ein einziges favicon.ico mit diesen Größen gepackt:

Size File Where it's used
16 × 16 px inside favicon.ico Das Symbol für Browser-Tab und Adressleiste bei Standard-Bildschirmdichte.
32 × 32 px inside favicon.ico Das Tab- und Lesezeichensymbol auf hochauflösenden Displays und die Windows-Taskleiste.
48 × 48 px inside favicon.ico Der größere Eintrag, aus dem Desktop-Verknüpfungen und Windows-Kacheln wählen können.

Format & container

Jede Größe innerhalb der .ico wird als verlustfrei PNG-codierter Eintrag gespeichert, sodass der Container selbst keinen Qualitätsverlust verursacht — nur der Detailgrad Ihrer Quellgrafik begrenzt, wie scharf das kleine Symbol wirkt.

How it's wired into your page

                <link rel="icon" href="/favicon.ico" sizes="any">
<!-- favicon.ico wird auch automatisch im Stammverzeichnis Ihrer Website gefunden -->
              

Tip

Behalten Sie die PNG-Transparenz in der Quelle bei, damit sich das Symbol sowohl in helle als auch in dunkle Browser-Tabs einfügt; fügen Sie nur dann eine deckende Hintergrundfarbe hinzu, wenn dünne Linien gegen eines der Themes verschwinden.

Häufig gestellte Fragen

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.
