Favicon (.ico) vs SVG
SVG is the most exciting favicon format of the modern era — vector, dark-mode aware, and tiny. But it cannot fully replace .ico in 2026. Here's why, and how to use both.
SVG scales infinitely and supports dark-mode media queries inside the file itself. A 1 KB SVG covers every density on every modern browser.
ICO is the universal fallback. Older Safari versions, legacy browsers, and the bare-URL <code>/favicon.ico</code> convention all still depend on it.
The recommended setup: ship <code>favicon.ico</code> + <code>favicon.svg</code>. Browsers that support SVG will prefer it; the rest fall back to .ico automatically.

Under 1 KB for a clean monochrome mark. Even complex multicolour logos rarely exceed 4 KB.
