What it does
Transfonter is a free online font converter with output-format, character-subset, hinting and CSS settings. It returns a ZIP containing the converted fonts and supporting web files.
Choose the output formats, required characters or Unicode ranges, font directory and font-display behavior. Add files through Upload your fonts, then click Convert and download the resulting ZIP. A demo page is optional.
The form accepts up to 20 files, with a 5 MB limit for each. Hinting can be retained, replaced or stripped, and vertical metrics can be adjusted. These changes affect the supplied font files, so use the generated demo to inspect the result before deployment. Conversion does not supply rights that the original font licence withholds.
Transfonter describes itself as a free service and accepts optional donations.
