UnicodeIt allows to convert LaTeX expressions to the corresponding Unicode characters. This provides an easy way to typeset simple mathematical expressions, greek letters or other symbols, and insert them inline into your text in any application, for instance Keynote or PowerPoint.

Note that not all LaTeX expressions are supported. Consider using LaTeXiT for more complicated formulas.

Installation on OS X

  • Download the Mac OS X app from their webpage
  • Double-click the UnicodeIt item and choose to install it as a service

  • Confirm by clicking Done in the next dialog.
  • You may optionally add a keyboard shortcut to the service in System Preferences -> Keyboard -> Shortcuts, for instance Command+Option+Shift+U as suggested by the developer.

Usage on OS X

  • In most applications, type your LaTeX formula, e.g. e^+ e^- \to 2\gamma
  • Select the text
  • In the application menu, go to Services and click UnicodeIt, or press your custom keyboard shortcut
  • The selected LaTeX expression should have been replaced by the unicode symbols.
