How do I convert SVG to ICO?

Upload your SVG file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting SVG to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

Will the ICO keep the transparent background?

Yes. ICO supports smooth, partial transparency, so transparent areas stay transparent.

SVG describes a picture as shapes and paths instead of pixels, so it stays crisp at any size. Social networks, email apps and many upload forms don’t accept SVG, which is why people convert it.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the SVG to ICO converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert SVG to ICO?

Transparent areas stay transparent: ICO supports smooth, partial transparency just like SVG.
One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.

What to expect when converting SVG to ICO

Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.
The SVG is drawn at a fixed pixel size, so the ICO won’t stay sharp if you enlarge it later. Keep the original for editing.
