What Icon Font Generator does and how it behaves

Icon Font Generator packages uploaded SVG icon files into one custom font and produces the CSS class mappings needed to place its glyphs on a page. It also creates a specimen page showing the generated icons and their classes together. The selected files are handled entirely in the browser and are not uploaded. The important distinction is that the result is a font, not inline SVG: each icon participates in text sizing, color, line height, and baseline alignment, while the original SVG element structure is no longer available to page CSS.

How the result is produced

1

Build the glyph set

Provide one SVG file for each icon you want in the font. The generator converts the submitted shapes into font glyphs, assigns characters to those glyphs, and associates them with CSS class mappings. Exact class names and character assignments are generated results, so inspect the produced mapping rather than guessing a Unicode value or writing the CSS content character from memory.

2

Verify the generated assets

The generated asset set includes the custom font, its CSS mappings, and a specimen page. Use the specimen to confirm that every source file became the intended glyph and to identify the corresponding class. When integrating the font, keep the supplied CSS and font files consistent. Changing a class name or a referenced font location without updating the mapping can prevent icons from appearing.

Good uses

  • Building a user interface that already renders icons through CSS classes but needs glyphs made from the project's own SVG artwork.
  • Combining a small, controlled group of interface symbols into one custom font and documenting the available classes with a visual specimen.
  • Preparing an internal icon set for developers who need both reusable font assets and a page that identifies which class displays each glyph.

Limits and checks

  • Treat generated class names and character assignments as part of the asset. After adding, removing, renaming, or regenerating icons, compare the new mapping before replacing a font already used by a site.
  • Complex SVG paint features may not translate cleanly into a font glyph. Multiple colors, gradients, masks, clipping, and stroke-dependent artwork require visual inspection; retain the original SVG when exact appearance or separately styled parts matter.
  • A visible glyph does not supply an accessible name. Meaningful controls still need an accessible text label, while decorative icons should be excluded from assistive technology according to the surrounding markup and interface design.

Common questions

Will every generated icon look exactly like its uploaded SVG?

Not necessarily. Simple single-color shapes with appropriate bounds are the safest sources, but font glyphs use font metrics and text rendering behavior. Detailed paint effects or artwork extending beyond its intended bounds can appear different or clipped. Check every glyph on the specimen page at several sizes. Use the SVG directly when preserving its exact rendering is essential.

Can I paste an emoji or Unicode character instead of uploading an SVG?

No. This tool's stated input is SVG icon files. Character assignments in the resulting font provide addresses for the generated glyphs; they do not import an existing system emoji or guarantee standard Unicode meaning. Supply the desired artwork as an SVG, then use the generated CSS class mapping rather than assuming that a particular character will select it.
