SVG to ICO: Why and How
Why ICO still matters
Modern browsers accept SVG favicons, but the `.ico` format remains the universal fallback: older browsers, Windows shortcuts, and some crawlers still expect `/favicon.ico` at the site root. The robust setup ships both — an SVG for modern rendering and an ICO fallback.
What a good conversion does
- An ICO is a container of multiple PNG sizes; 16×16, 32×32, and 48×48 cover browser tabs, taskbars, and search results (Google wants a multiple of 48px).
- Complex SVG details vanish at 16px. If your logo has fine lines, consider a simplified mark for the smallest sizes.
- Keep the background transparent unless the mark needs contrast help in dark UIs.
After converting
Place `favicon.ico` at the site root (many tools request it by convention even without a `<link>`), add `<link rel="icon">` for the SVG, and remember favicons cache hard — rename or version the file to force refresh.
