About this converter

ICO files are Microsoft's icon format. They are used as website favicons and Windows application icons, and they often contain multiple image sizes packed into a single file (16x16, 32x32, 48x48, up to 256x256). The problem is that most image editors and design tools do not open ICO files natively. This converter loads the ICO using the browser's built-in icon decoder, renders it to a Canvas element, and exports a standard PNG. The browser picks the largest available size from the ICO file. Everything runs locally in your browser.
