SVG to ICO Converter

SVG is a vector format described in XML — instead of a pixel grid, it stores shapes and paths, so it stays crisp at any size.

Scalable Vector Graphics is, technically speaking, not an image format at all — it's an XML-based markup language that describes shapes, curves, and text mathematically rather than as a grid of pixels. That's what gives it its defining trait: an SVG can be scaled up to billboard size or down to a favicon without a single pixel of quality loss, because it's redrawn from the underlying math at whatever size it's displayed. It's also just a text file, so it can be opened and hand-edited in any code editor, styled with CSS, and even animated — which is why it's become the standard choice for logos, icons, and illustrations on the modern web.

ICO is the Windows icon container format — it can bundle several sizes of the same image into one file for favicons and app icons.

ICO was built for exactly one job: giving Windows a single file that holds several resolutions and color depths of the same icon, so the operating system can pick whichever version fits — a small taskbar icon versus a large desktop shortcut, for instance — without any scaling. That same trick is why browsers still expect a site's favicon.ico to work the same way: one file, several embedded sizes, used at whatever resolution the browser tab needs.
