Is the ICO still a vector?

No. ICO frames are bitmaps. Your SVG is rasterized before packing.

What if my SVG has no width or height?

We render into a 512×512 canvas using the viewBox when present, then downscale for 16 and 32.

Scripts or external images in SVG?

Only what the browser will paint from a data URL. Prefer self-contained SVGs without remote assets.

SVG to ICO converter

Browsers love SVG favicons, but some environments still want favicon.ico. We draw your SVG to a canvas, then pack 16×16 and 32×32 PNG frames into one ICO. The result is raster, not a vector icon container.

Rasterization

SVG is drawn at a working size (512×512 if the file has no intrinsic size), then scaled into each ICO frame. Fine strokes may need a thicker source mark.

Keep the SVG too

For modern browsers, also ship favicon.svg from the generator or your design file. ICO is the compatibility fallback.
