TrueType Font (TTF) was developed jointly by Apple and Microsoft in the late 1980s as an alternative to Adobe's Type 1 fonts. The format uses quadratic Bezier curves to define glyph outlines and includes instruction-based hinting for precise rendering at small sizes. TTF fonts are fully scalable, meaning they render crisply at any size without pixelation. The format became the standard for desktop publishing and remains widely used today.

TTF files contain complete font data including character outlines, kerning tables, and hinting instructions. They work on all major operating systems (Windows, macOS, Linux) and are ideal for desktop applications and print design. While TTF files are larger than web-optimized formats like WOFF2, they provide maximum compatibility and are the source format for font conversion workflows.
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.
