How to convert SVG to ICO
SVG files are vector graphics that scale perfectly to any size, making them ideal source material for creating ICO files. An ICO file bundles multiple raster sizes (16x16, 32x32, 48x48, 256x256) into a single file so Windows and browsers can display the right size for each context. Converting your SVG logo or icon to ICO is the standard step for creating a website favicon or a Windows application icon.
BoltConverter converts your SVG to ICO in your browser using WebAssembly. The converter rasterizes the SVG at each required icon size and packages them into a single .ico file. Your files never leave your device during this process.
Select your SVG file
Click the upload box or drag your SVG file onto the page. The SVG should be a square design for best results as icons.
SVG is rasterized at multiple sizes
WebAssembly renders the SVG at 16x16, 32x32, 48x48, and 256x256 pixels and packages them into a single .ico file in your browser.

Frequently asked questions
Why use SVG as the source for an ICO file?
SVG is vector-based and scales losslessly, so rasterizing it at multiple ICO sizes produces crisp images at every size. Starting from a low-resolution raster image for ICO creation often produces blurry results at larger sizes.
What sizes are included in the output ICO?
The output ICO file includes 16x16, 32x32, 48x48, and 256x256 pixel versions. These cover all standard Windows icon display contexts and browser favicon sizes.
Are my files uploaded to the internet?
No. The conversion runs entirely in your browser using WebAssembly. Your SVG files never leave your device.
Should my SVG be square?
Yes. Icon files are square, so your SVG viewBox should have equal width and height dimensions. Non-square SVGs will be letterboxed or cropped to fit a square ratio.
How do I use the ICO as a website favicon?
Name the file favicon.ico and upload it to your website's root directory. Add <link rel="icon" href="/favicon.ico"> to the <head> of your HTML pages for explicit browser support.
