A format for displaying and storing OpenType fonts. It can be scaled without losing font quality. Today the OTF library has more than 10 thousand fonts. Practically all fonts known today have an OpenType version. The format was based on Postscript and supports Unicode. It was initially developed by Microsoft, but today it belongs to Adobe.
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. It was developed by the Mozilla Foundation.
