TTF vs OTF: TrueType vs OpenType
Both are desktop formats. The real difference sits in the outline curves and the typography features they carry.
| TTF | OTF | |
|---|---|---|
| Outline curves | Quadratic Bezier | Cubic Bezier (PostScript/CFF) |
| Advanced typography | Limited | Ligatures, alternates, richer OpenType features |
| Common source | Apple and Microsoft desktop fonts | Professional type foundries |
| Compression | None | None |
When to use TTF
TTF is the safer universal pick when a tool or platform doesn't clearly say it supports OpenType or CFF.
When to use OTF
OTF wins when you actually need the extra typography a foundry built into the font.
