OpenType Features Editor

OTFE Main Screen

OpenType Features Editor is a Windows utility for font developers who want to reduce some of the tedium of adding OpenType features like ligatures and stylistic alternates to their fonts. It opens standard Adobe font metrics (.afm) files and automatically generates OpenType features based on configurable glyph name mapping that can then be saved as a features (.fea) file. That means OTFE will work in any font development workflow that can handle exporting an Adobe font metrics file and importing an OpenType features file.
