SVG to ICO Converter for Multi-Size Icons and Favicons
Turn a scalable SVG logo or symbol into one real ICO file with the sizes Windows and browsers expect. Keep transparency, choose individual resolutions, and convert locally.
The SVG is sanitized and converted locally. It is never uploaded.
No SVG selected
Choose a vector logo or symbol to create a Windows icon and favicon-compatible ICO.
How to convert SVG to ICO online
Choose an SVG, select the icon resolutions and background, then download one multi-resolution ICO file.
Choose an SVG file
Select one .svg vector file up to 5 MB. Scripts, event handlers and external resource links are removed before rendering.
Select icon sizes
Choose any combination of 16, 24, 32, 48, 64, 128 and 256 pixels, plus transparent, white or black background.
Download the ICO
Convert and download one .ico file containing a PNG image layer for every selected resolution.
Choose SVG to ICO sizes and background
An ICO can contain several raster images so Windows and browsers can choose the sharpest layer for each context.
| Control | Setting | Effect |
|---|---|---|
| Icon sizes | 16-256px | Packages multiple resolutions so each interface can choose an appropriate sharp layer |
| Background | Transparent, white or black | Keeps alpha or flattens the SVG onto a solid square |
| Aspect ratio | Fit and center | Keeps the complete SVG visible without stretching it |
| Processing | Local browser | The SVG and generated icon are never uploaded to a server |
SVG vs ICO for icons and favicons
SVG remains resolution-independent, while ICO packages fixed-size raster layers for legacy and Windows compatibility.
| Characteristic | Source | Output |
|---|---|---|
| Image model | Scalable vector shapes | Container of fixed-size raster images |
| Resolution | Scales without pixelation | Uses included 16-256px layers |
| Transparency | Supported | Supported by embedded PNG layers |
| Common use | Web graphics, logos and interfaces | Windows applications, shortcuts and favicon.ico |
| Editing | Editable paths, fills and strokes | Raster output; edit the SVG source instead |
How multi-size ICO conversion works
The browser sanitizes and rasterizes the SVG independently at every selected size, then packages the PNG layers in an ICO container.
One file contains several icon sizes
The ICO directory points to separately rendered PNG layers, rather than stretching one bitmap for every Windows or browser context.
Transparency is preserved
Choose Transparent to retain the SVG alpha channel in every PNG layer, including soft antialiased edges.
The SVG is sanitized first
Scripts, inline event handlers, foreignObject content and external resource URLs are removed before the browser renders the image.
Small icons still need visual review
Fine vector details can disappear at 16 or 24 pixels. Simplify the source SVG when its smallest layers are not recognizable.

SVG to ICO converter FAQ
How do I convert SVG to ICO?
Choose an SVG file above, select the required icon sizes and background, then select Convert to ICO and download the multi-resolution file.
Is this SVG to ICO converter free?
Yes. You can create ICO files within the displayed SVG file limit without signing in or installing software.
Is my SVG uploaded to a server?
No. SVG sanitization, rasterization, PNG encoding and ICO packaging all run locally in your browser.
What sizes should an ICO contain?
For broad use, include 16, 32, 48, 64, 128 and 256 pixels. The 16px layer serves compact interfaces, while 256px supports large Windows icon views.
Can I use the ICO as favicon.ico?
Yes. Include at least 16px and 32px layers, download the file, name or keep it as favicon.ico, and reference it from your website.
Does the ICO preserve SVG transparency?
Yes, when Transparent is selected. Each icon layer is stored as a PNG with alpha inside the ICO container.
Does converting SVG to ICO keep vector graphics?
No. ICO layers are raster images. The tool renders the SVG separately at each selected size so the output remains sharp at those exact resolutions.
Why does my 16px icon look unclear?
Very small icons cannot show fine paths or text clearly. Simplify thin strokes and small details in the SVG, then generate the ICO again.
Can I create a Windows application icon from SVG?
Yes. Include several resolutions through 256px and use the generated ICO in the icon setting of your Windows application or installer.
Is the downloaded file a real ICO?
Yes. It contains a standard ICO header and directory followed by one valid PNG image for every selected size; it is not a renamed SVG or PNG.

Select your resolutions and background, then turn one SVG into a private Windows icon or favicon.
