.ico (Icon File) The .ico format is used for icon files in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, so they may be scaled appropriately in different contexts. These files are commonly used to display a small image next to a website's name in a browser's address bar, as well as for application icons on both Windows desktop and mobile platforms.

.svg (Scalable Vector Graphics) The .svg format is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. They are scalable to different sizes without losing quality, making them ideal for high-resolution displays and responsive web design.
