Quick Tool Overview

The Image to ICO Converter builds a genuine multi-size .ico file — the container that holds 16, 32, 48 and 256 pixel versions of an icon so Windows and older browsers can each pick what they need. Every size is rendered separately from your source rather than scaled from one render, which keeps the small ones crisp.

About the Image to ICO Converter

The .ico container holds several sizes of the same icon in one file, and Windows and older browsers pick whichever they need. That is why favicon.ico is still worth shipping even in a world of PNG icons.

Pick which sizes to include — 16 and 32 cover browser tabs, 48 covers the Windows desktop, and 256 is for high-density displays — and each is rendered separately from your source rather than scaled down from one render, which keeps the small sizes crisp. The file is assembled byte by byte in the browser as a genuine ICO, not a PNG with the extension changed.

Key features of the Image to ICO Converter

A real ICO container

The header and directory entries are written properly, not a PNG with the extension changed.

Each size rendered separately

Small sizes come from the original rather than from a downscale of a downscale, so they stay legible.

Small-size previews

You see the 16 and 32 pixel versions before shipping, which is where most logos fall apart.

Pick the sizes you want

Include only what you need, so the file stays a few kilobytes.

Transparency kept

The alpha channel survives into every embedded size, so the icon sits cleanly on any tab colour.

How to use the Image to ICO Converter

  1. 1

    Add a square image

    A square source works best. Anything else is padded rather than stretched.

  2. 2

    Choose the sizes

    16 and 32 are essential; 48 and 256 are worth including for Windows and high-density screens.

  3. 3

    Check the small previews

    A logo that reads fine at 256 can be mud at 16 — the previews show that before you ship it.

  4. 4

    Download the .ico

    Put it at the root of your site as favicon.ico.

Frequently asked questions

It remains the reliable fallback. Browsers request /favicon.ico by default even without a link tag, and some tools and feed readers only look for it.
