[Online Tool] How to Make a favicon.ico — Free Online ICO Icon Generator

Anyone who has built a website has run into this: other sites display a crisp little icon in the browser tab, while yours shows a blank default — looking unfinished by comparison.

That small icon in the browser tab is called a favicon, and its file format is .ico. Many people don't know how to make one, or can't find a good free tool — and eventually just give up.

Toolshu's ICO Icon Generator takes three steps: upload an image, choose your sizes, download the .ico file. Completely free, no Photoshop, no account required.

What Is a Favicon and Why Does It Matter?

A favicon (short for Favorites Icon) is the small icon displayed in browser tabs, address bars, bookmarks, and browser history entries.

Its role is more important than most people realize. When a user has a dozen tabs open at once, the favicon is the only visual cue that identifies which tab belongs to which site. A site without a favicon has zero recognizability in a multi-tab environment.

For brand websites, personal blogs, and tool sites, a well-designed favicon is a basic marker of professionalism.

Supported Sizes

One of the key features of the ICO format is that it can bundle multiple sizes into a single file — the browser automatically selects the most appropriate size depending on where it's displayed.

Commonly used sizes include 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. The tool lets you download a single size or check multiple sizes to export as a ZIP — ready to drop into your website.

How to Add favicon.ico to Your Website

Once you have your .ico file, there are two ways to activate it:

Method 1 (recommended): Rename the file favicon.ico and upload it to your website's root directory — the same level as index.html. Most browsers detect it automatically, no extra code needed.

Method 2 (code reference): Add this line inside your page's <head> tag:

<link rel="icon" type="image/x-icon" href="/favicon.ico">

Both methods work. Placing the file in the root directory is simpler.

What Kind of Image Works Best?

Use a square image: Favicons are square — uploading a non-square image will cause it to be squashed or stretched. Crop to square before uploading.

Start with 256×256 px or larger: Scaling down from a large image always produces cleaner results than scaling up from a small one. Upload a large image and let the tool shrink it.

Simple shapes over complex artwork: A favicon may ultimately be displayed at just 16×16 pixels. Intricate designs become unreadable at that size. Choose something with clear outlines and strong color contrast.
