Description The OTF file is most commonly associated with computer fonts. It was developed by both Adobe and Microsoft and introduced to Mac OS X and Windows 2000. This OpenType Font format is similar to the TTF (TrueType Font) format. What sets the OTF format apart from other font file formats is that it is scalable. It belongs to TrueType and OpenType font formats and has analog compression that stores rendering technology. In WOFF, it's possible to store individual metadata with font info. It's been used since 2010 for the main purpose of storing and transferring fonts on the Internet. The Mozilla Foundation developed it.
Technical details Like TrueType Font files, the OTF format also contains aspects of the equally popular PostScript format, creating a single file that combines both aspects. OTF files have several major advantages. They are fully scalable and can thus be resized without any loss in quality. Furthermore, they contain new line and typographic layouts with the already known technology of TrueType and PostScript.
