Convert OTF to WOFF

Wraps an OpenType font for web delivery. The cubic curves and OpenType features come through unchanged - WOFF is a container, not a conversion, so nothing about the typeface is altered.

What is OTF?

OpenType, which extends TrueType with cubic curves and the typographic machinery that makes real typesetting possible - ligatures, alternates, small caps, proper kerning. Where a typeface has ambitions, it usually ships as OTF.

What is WOFF?

Not a typeface format but a wrapper: a TrueType or OpenType font compressed for the web, typically 40% smaller, and what @font-face expects. The outlines inside are untouched, so unwrapping one gives back exactly the font that went in.
