Frequently Asked Questions

What is the difference between OTF and TTF?
Both are OpenType fonts, but they differ in outline format. OTF uses CFF (cubic Bézier curves) — more compact and preferred by designers. TTF uses TrueType (quadratic curves) — better screen hinting on Windows. For most web use, the difference is negligible.
Can I use OTF fonts on the web?
Yes — all modern browsers support OTF via @font-face. However, for best web performance, convert OTF to WOFF2 first (30% smaller). Use OTF as a fallback. Tools: Google's woff2 compressor, FontSquirrel, or fonttools.
Should designers use OTF or TTF?
Designers typically prefer OTF for print work — CFF outlines produce smoother curves with fewer control points. TTF is preferred for screen-first design where Windows hinting matters. Many professional fonts ship in both formats.
Do OTF fonts work on Windows?
Yes. Windows has supported OTF fonts since Windows 2000. You can install OTF fonts by double-clicking the file or dragging it to C:\Windows\Fonts. All modern Windows applications (Office, Adobe, browsers) render OTF correctly.
