How it works

How to use PNG to ICO

  1. Drop your PNG — a square image with a transparent background works best.

  2. Optionally adjust padding, shape or background colour.

  3. Check the previews at 16, 32 and 48 px.

  4. Download the .ico file.

Why use it

Why use our PNG to ICO tool

Multi-size .ico

One .ico file contains 16×16, 32×32 and 48×48 icons, so it looks sharp in browser tabs and Windows.

Transparency kept

PNG alpha channels are preserved inside the ICO.

Full favicon set if you want it

Need Apple touch and Android icons too? Grab the full package zip with HTML tags.

Private and instant

The ICO is built in your browser; your logo is never uploaded.

FAQ

Frequently asked questions

What size should my PNG be?

Square and at least 256×256 px gives the cleanest result. Non-square images are centred with transparent padding.

Which sizes are inside the .ico?

16, 32 and 48 px — the sizes browsers and Windows actually use for favicons and shortcuts.

How do I use the .ico as a favicon?

Upload it to your site's root as favicon.ico, or link it with <link rel="icon" href="/favicon.ico">.

Can I convert JPG or SVG to ICO?

Yes, any image works, but PNG or SVG with transparency gives the best-looking icons.
