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
- Add your PNG — drag & drop, paste, or choose a file (JPG, WebP, and SVG work too).
- Set the background — keep transparency or add a solid color if your PNG has fine detail.
- Check the previews — confirm the 16 and 32 px versions stay readable.
- 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.
the .ico container: sizes and where each is used
A .ico file is an icon container that can hold several bitmaps in one file, which is exactly what a favicon needs. Your PNG is downscaled and packed into a single favicon.ico holding these sizes:
| Size | File | Where it's used |
|---|---|---|
| 16 × 16 px | inside favicon.ico | The browser tab and address-bar icon at standard screen density. |
| 32 × 32 px | inside favicon.ico | The tab and bookmark icon on high-DPI displays and the Windows taskbar. |
| 48 × 48 px | inside favicon.ico | The larger entry desktop shortcuts and Windows tiles can pick from. |
Format & container
Each size inside the .ico is stored as a lossless PNG-encoded entry, so there is no quality loss from the container itself — only your source art's detail limits how crisp the small icon looks.
How it's wired into your page
<link rel="icon" href="/favicon.ico" sizes="any">
<!-- favicon.ico is also found automatically at your site root -->
Tip
Keep PNG transparency in the source so the icon blends into both light and dark browser tabs; only add a solid background colour if thin lines disappear against one of the themes.

Frequently asked questions
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.
