Why do I need an ICO file?
While modern browsers support `.png` and `.svg` favicons, older browsers and some feed readers still explicitly look for `favicon.ico` in the root of your domain. Providing a valid `.ico` file ensures your brand is represented correctly everywhere.
How this converter works
This tool uses the browser's native rendering capabilities to resize your image perfectly, and then wraps the resulting PNG data into a standard Windows Icon Resource (ICO) header. Modern ICO files support PNG compression, which keeps the file size incredibly small while retaining full 32-bit transparency.
