About the OTF format
OTF — OpenType Font
OpenType is the current industry standard font format, jointly developed by Adobe and Microsoft. It extends TrueType with support for cubic Bézier curves (PostScript outlines), advanced typographic features (ligatures, small caps, contextual alternates), and extended Unicode coverage.
Common uses
- Professional typography and publishing
- Advanced typographic design with OpenType features
- Multilingual document production
- Cross-platform font distribution
About the WOFF format
WOFF — Web Open Font Format
WOFF is a compressed web font format wrapping TrueType or OpenType fonts with metadata. Designed specifically for web delivery, WOFF reduces font download size by applying zlib compression, making web typography faster and more efficient than loading raw TTF/OTF files.
Common uses
- Web font delivery for CSS @font-face
- Reducing web page font loading time
- Cross-browser web typography
- Legacy browser web font support (pre-WOFF2)
