IronOCR prend en charge 125 langues internationales, mais seul l'anglais est installé par défaut dans IronOCR.

Des modules linguistiques supplémentaires peuvent être facilement ajoutés à votre projet C#, VB ou ASP.NET via NuGet ou sous forme de DLL téléchargeables et ajoutables comme références de projet.
