SVG to ICO Converter — Free, Online, No Upload

SVG is the ideal source format for creating favicons and application icons — it's scalable, so it produces sharp results at every icon size. But browsers and operating systems use ICO as the favicon format, not SVG (though modern browsers support SVG favicons, older browsers and all versions of Windows Explorer still require ICO for full compatibility).

Converting SVG to ICO generates a multi-resolution icon container that includes the 16×16, 32×32, and 48×48 pixel sizes browsers and Windows need. The scalable nature of SVG means the converter can render the icon precisely at each target size, giving you sharper results than converting from a fixed-size raster source. For this reason, SVG is actually the best possible starting point for ICO creation.

For best results, the SVG should be a square graphic with a clean, bold design. Complex illustrations with fine detail won't be readable at 16 pixels wide, so simplify the design before converting if needed. After generating the ICO, test it with a favicon checker tool — view it in multiple browsers, check how it looks on mobile home screens, and verify the Windows taskbar appearance. Tools like RealFaviconGenerator can further optimize the ICO for cross-platform deployment. Most modern sites also include a separate SVG favicon tag alongside the ICO for browsers that support it.

Typical sizes: SVG 5–50 KB (simple logo); ICO 10–100 KB (multi-size icon).

Both formats keep every pixel, so the ICO looks the same as the SVG.
