OpenType Font (OTF) was developed jointly by Adobe and Microsoft in the 1990s, combining the best of TrueType and PostScript Type 1 formats. OTF files use cubic Bezier curves (CFF/PostScript outlines) which are preferred by professional typographers for their precision. The format supports advanced typographic features including ligatures, stylistic alternates, small caps, and contextual substitutions.

OTF fonts are the standard for professional design work and are fully supported on Windows, macOS, and Linux. They can contain up to 65,536 glyphs, enabling comprehensive language support and extensive alternate character sets. While larger than web-optimized WOFF2, OTF provides the complete font feature set needed for desktop publishing, print design, and as the source format for web font generation.
WOFF2 (Web Open Font Format 2) is a font format optimized for web delivery, developed by the W3C with Google's contributions. It uses Brotli compression to achieve files that are 30% smaller than WOFF and up to 50-70% smaller than TTF. WOFF2 became a W3C Recommendation in 2018 and is now supported by over 97% of browsers worldwide, making it the preferred format for web fonts.

WOFF2 wraps TTF or OTF font data with metadata and applies Brotli compression, which browsers decompress natively during page load. The format preserves all font features including OpenType layout tables, variable font axes, and color emoji support. For web performance, WOFF2 should be served with proper caching headers and is typically the only web font format needed for modern browser support.
