When to Use ICO Format
ICO is a container format that can hold an icon at several sizes in a single file, which is exactly what browsers and Windows expect when they display your image at different scales. Reach for ICO when you need:
- A favicon — the tiny icon in browser tabs, bookmarks, and history. The classic
favicon.icofile must be in ICO format. - Windows icons for desktop shortcuts, taskbar pins, and executables, where
.icois the native format. - Icons that must render crisply at multiple sizes — favicons are commonly requested at 16×16, 32×32, and 48×48, while Windows also uses larger 256×256 icons.
- Maximum browser compatibility, including older versions that don't reliably support PNG or SVG favicons.
For app icons, illustrations, or anything shown at a single large size, a normal image format is a better fit — see our image format by use case guide to pick the right one.
How to Add Your ICO as a Favicon
After converting your WebP to ICO, upload the file to your website's root directory and add this line to your HTML head:
<link rel="icon" href="/favicon.ico" type="image/x-icon">Most browsers also look for favicon.icoin the root directory automatically, so placing the file at yourdomain.com/favicon.ico often works without any HTML changes. Start from a square WebP — ideally 512×512 or larger — so the icon stays sharp when it's scaled down.
Frequently Asked Questions
How do I convert a WebP to ICO?
Drop your WebP file into the converter above, choose ICO from the Output Format menu, and download the result. Everything runs in your browser, so the WebP is never uploaded to a server and the .ico file is saved straight to your device.
Can I use a WebP as a favicon?
Not directly in the classic favicon.ico slot — that file must be in ICO format. Convert your WebP to ICO first, then reference it with a <link rel="icon"> tag or drop it at your site's root. Modern browsers also accept PNG favicons, but ICO remains the most broadly compatible choice.
Is the WebP to ICO converter free?
Yes. There is no sign-up, watermark, or file limit. Conversion happens locally in your browser with JavaScript, so it is both free and completely private.
What size is the ICO file?
The converter produces a 32×32 pixel ICO, the most widely used favicon size and a safe default for browser tabs, bookmarks, and Windows shortcuts. Start from a square WebP so the icon scales down cleanly.
