Compare OpenType Font and TrueType Font formats — understand the key differences and when to use each
OpenType Font
OpenType Font (.otf) is a font file format.
TrueType Font
TTF (TrueType Font) is a scalable font format developed by Apple and Microsoft in the late 1980s as a competitor to Adobe's PostScript fonts. TTF uses quadratic Bézier curves to define glyph outlines, providing high-quality rendering at any size. TrueType fonts include hinting instructions that optimize rendering on screen at small sizes. TTF is supported by all major operating systems and applications. While OpenType (OTF) has largely succeeded TrueType for professional typography, TTF remains widely used and universally compatible.
