Have you ever needed to quickly check what’s inside a .ico file? Windows icons often contain multiple sizes and color depths, but most image viewers only show you one. That’s where our free ICO Preview tool comes in. It lets you open an ICO file right in your browser, explore all embedded icons, zoom in on details, and even export your favorite icon as a clean PNG image.
