OTF vs TTF vs WOFF2: font formats explained

Bought a font and not sure which file to use where? Here's the plain-English version of the main formats.

OTF (OpenType)

The modern, all-purpose desktop format. It supports advanced typographic features and works in every major design app. If you're designing logos, posters, or documents on your computer, OTF is a great default.

TTF (TrueType)

An older but extremely widely supported desktop format. It works almost everywhere, which is why some directories and older software prefer it. For most design work, OTF and TTF are interchangeable.

WOFF2 (Web Open Font Format)

The format built for websites. It's a compressed font designed to load fast in browsers via @font-face. If you're embedding type on a website, you want WOFF2 — not OTF or TTF, which are heavier and meant for desktop.

Which should you use?

• Designing on your computer (logos, print, posters): OTF (or TTF).
• Live text on a website: WOFF2, loaded with @font-face.
• Inside an app or product: usually OTF/TTF, embedded — and that needs an app license.
