SVG to ICO Converter
Render an SVG logo into a crisp multi-size .ico — every size is drawn from the vector, so 16 px is as sharp as 256 px — for favicons and Windows app icons.

About the SVG to ICO Converter
SVG is the ideal source for icons because it can be rendered at any size without blur. Rendering each ICO size directly from the vector avoids the mushy look you get from scaling one large bitmap down.
The SVG is rendered by your browser at the scale you choose (SVGs without a width and height are drawn at 1024 px), so the result is as sharp as the vector allows.
The ICO is assembled by our own encoder: each size is rendered from your image with high-quality stepped downscaling, then stored either as a PNG entry (compact; Windows Vista and later) or as a classic 32-bit BMP entry with an AND transparency mask (works on every Windows version), behind a standard ICONDIR directory.

Things to know
- Thin strokes vanish. Hairline strokes can disappear at 16 px. Check the preview and thicken strokes in the SVG if needed.
- Text in SVGs. Fonts that aren't installed are substituted; outline text in your editor first.
