ICO is an image file format used for icons in Windows and website favicons. ICO files can contain multiple image sizes (like 16x16, 32x32, 48x48) in a single file, allowing the operating system or browser to choose the best size for the context.

Why convert SVG to ICO for favicons?

While modern browsers support SVG favicons, ICO format ensures compatibility with older browsers and Windows systems. ICO files can contain multiple resolutions in one file, providing crisp icons across all display densities without requiring separate files for each size.

What icon sizes should I include?

For website favicons, include at least 16x16, 32x32, and 48x48 pixels. The 16x16 size appears in browser tabs, 32x32 in browser bookmarks, and 48x48 in Windows shortcuts. Adding 64x64 provides better quality on high-DPI displays.

Does transparency work in ICO files?

Yes! This converter preserves transparency from your SVG when creating ICO files. The alpha channel is maintained in the 32-bit color depth used for the ICO format, ensuring your transparent backgrounds display correctly on all background colors.

Can I use this for Windows application icons?

Absolutely! This converter creates standard ICO files suitable for Windows applications. Include larger sizes (32x32, 48x48, 64x64) for desktop applications to ensure your icon looks sharp in different contexts like taskbar, desktop shortcuts, and file explorers.

Yes! All conversion happens directly in your browser using HTML5 Canvas API. Your SVG files are never uploaded to any server, ensuring complete privacy and security. The entire conversion process takes place locally on your device.
