OTF
OpenType Font
The OpenType Font (.otf) is a scalable vector font format developed jointly by Microsoft and Adobe, widely used for professional typography across operating systems.
What is OpenType Font?
OpenType (.otf) builds on the earlier TrueType architecture, incorporating PostScript font data and supporting advanced typographic features like ligatures, small caps, and alternate glyphs. It ensures consistent rendering across both Windows and macOS platforms, making it an industry standard for designers and publishers.
