What is an OTF file?

An OTF file is a font file saved in the OpenType format developed by Adobe and Microsoft. It combines aspects of the PostScript and TrueType font formats. OTF fonts are fully scalable, meaning the characters can be resized without losing quality.

More Information

The OpenType font format is supported by macOS and Windows 2000 and later. OTF files must be stored in the system Fonts directory in order to be accessible by applications.
