SVG to ICO — Vector Favicons and ICO Fallback
Modern browsers support SVG favicons natively, but older browsers and some contexts still require ICO files. The best strategy is to provide both: an SVG favicon for modern browsers and a multi-resolution ICO as a fallback. This guide explains how to convert your SVG into a proper ICO file.
Output Sizes
| Size | Format | Purpose |
|---|---|---|
| 16x16 | ICO layer | Legacy browser tab |
| 32x32 | ICO layer | Retina legacy browsers |
| 48x48 | ICO layer | Windows shortcuts |
| any | SVG | Modern browser favicon |

Best Practices
- 1Serve an SVG favicon with <link rel="icon" type="image/svg+xml" href="/icon.svg"> for modern browsers.
- 2Also include <link rel="icon" href="/favicon.ico"> as a fallback for legacy support.
- 3Keep the SVG simple — it needs to be recognizable at 16px in a browser tab.
- 4When converting to ICO, render the SVG at 16, 32, and 48px and embed all three in the ICO container.
Common Mistakes
- Serving only SVG without an ICO fallback — Internet Explorer, some email clients, and older apps cannot display SVG favicons.
- Converting SVG to ICO at only one resolution — ICO files should contain multiple sizes (16, 32, 48px).
- Not specifying the SVG MIME type in the link tag — browsers need type="image/svg+xml" to use the SVG favicon.
- Using complex SVG features (filters, gradients) that render poorly at 16px — simplify for small sizes.

Open GeneratorFrequently Asked Questions
Can I use SVG as a favicon?
Yes. Modern browsers (Chrome, Firefox, Edge, Safari 15+) support SVG favicons. Add <link rel="icon" type="image/svg+xml" href="/icon.svg"> to your HTML head.
Do I still need an ICO file if I have an SVG favicon?
Yes, for maximum compatibility. Some browsers, email clients, and bookmark tools still only support ICO. Include both SVG and ICO favicon links.
How do I convert SVG to ICO?
First render your SVG to PNG at 16, 32, and 48 pixels, then package those PNGs into a multi-resolution ICO container. A generator tool can automate this process.
