Documentation
What is an icon font?
An icon font packages icons into a font file so you can render them via CSS font-family. Compared with images, icon fonts are lightweight, scalable, and easy to style with CSS. Popular icon font libraries include Font Awesome and Material Icons.
Note
This tool generates CSS mappings only. To produce actual font files (WOFF/WOFF2/TTF, etc.), use svgtofont, iconfont-cli, or FontForge.
Why use a custom icon font
- Reduce HTTP requests and improve load performance
- Style icons easily with CSS (size, color, states)
- Keep icons sharp at any scale
- Add animations and interactions more conveniently
How SVG-to-font works
- Prepare SVG icons: keep each file as a single icon with clean paths
- Optimize SVG: remove metadata and reduce file size
- Generate CSS mapping: assign Unicode points and class selectors
- Build fonts: convert SVG into WOFF/WOFF2/EOT/TTF using svgtofont/iconfont-cli/FontForge
- Integrate: include the font files and CSS, then use the icon classes
Example
<!-- Use in HTML -->
<i class="icon icon-home"></i>
<i class="icon icon-user"></i>
<!-- CSS -->
.icon {
display: inline-block;
font-family: 'icon-font';
font-size: 24px;
color: #333;
}
/* Hover effect */
.icon:hover {
color: #007bff;
transform: scale(1.1);
}Icon Font vs SVG Sprite
| Feature | Icon Font | SVG Sprite |
|---|---|---|
| Browser support | Requires @font-face support | All modern browsers |
| CSS control | Color, size, shadow | fill, stroke |
| Performance | Load once, cache-friendly | Load on demand |
| Best for | Monochrome icon sets | Colorful or complex icons |
FAQ
Where are the font files?
This tool generates CSS mappings only. Use svgtofont, iconfont-cli, or FontForge to convert SVG files into WOFF2/WOFF/TTF font files.
Why do some icons render incorrectly?
Common reasons include complex SVG structures, stroke-only shapes, or inconsistent viewBox sizing. Prefer simple monochrome SVGs with clean, closed paths.
How compatible are icon fonts?
Icon fonts are widely supported in modern browsers. For legacy environments, consider providing additional formats such as EOT as a fallback.
