OTF

Open Type Font

Open Type Font or OTF is the successor of the True Type Font Format. OTF fonts are scalable. Its typographic structure retains certain elements of the True Type Format with the addition of multiple data structures that are unique to this font type. The font in OTF can easily be scaled, resized, or shaped without affecting the extension's quality due to its enhanced features.
