OpenType font represents an evolution of TTF files. OTF was created to enable more functions than TTF.
OTF (OpenType Font) is a font file format used to store fonts for use in computer applications. It was introduced in the late 1990s as an extension of the TTF (TrueType Font) format, and has since become a popular choice due to its flexibility and compatibility. The OTF file format stores font information as a collection of tables that describe the shape and appearance of each character in the font. Each table contains information about the x-height, ascenders, descenders, and other characteristics of the character, as well as advanced features such as ligatures and contextual alternates. The size of an OTF file depends on the number of characters and the complexity of the font, but it is generally larger than TTF files due to its additional features. One of the main advantages of OTF files is their ability to include advanced typographic features such as ligatures, contextual alternates, and language support.
