Fontprep: Open-Source Font Editor & Converter

Optimize fonts for web use with Fontprep, a free and open-source font editor and converter that subs, compresses, and converts formats for faster loading.

What is Fontprep?

Fontprep is an open source font editor and converter developed by Fontello that helps prepare fonts for web use. It has features for subsetting fonts to only include necessary glyphs, compressing font files to reduce size, and converting between formats like OTF/TTF to WOFF and WOFF2.

Fontprep is useful for web developers to optimize fonts before using them on websites. Loading giant font files can slow down page load times, so subsetting and compression helps improve performance. Converting to more web-friendly formats like WOFF and WOFF2 ensures broader browser compatibility.

Some key features include:

• Subsetting - Reduce font file size by only including necessary glyphs
• Compression - Optimize fonts using brotli/gzip to reduce transfer size
• Format conversion - Convert between OTF, TTF, WOFF, WOFF2 formats
• Glyph renaming - Rename glyphs for optimization
• Unicode coverage analysis - Understand what Unicode characters are covered

With its focus on font optimization and conversion, Fontprep makes it easier for developers to prepare fonts for using on the web through a friendly graphical interface. The open source nature also allows customization and integration into font loading pipelines.
