SVG → ICO - Quick Cheat Sheet

Multiple sizes: A single .ico can contain several images (e.g., 16, 32, 48, 256 px). Windows picks the best match.
Transparency: PNG-in-ICO preserves alpha. Use a solid background if you want opaque icons.
Scaling: For logos, "Aspect fit" is safest. "Cover" crops edges to fill. "Stretch" distorts-use only if needed.
SVG advice: Prefer a square viewBox. Convert custom fonts to paths or embed fonts for consistent text rendering.
CORS: External <image href="..."> or CSS may be blocked when drawing to canvas.
Favicon tip: Save as favicon.ico and link in HTML: <link rel="icon" href="/favicon.ico">
