Using Custom Language Files

Iron Tesseract OCR fully supports custom or downloaded languages and fonts following the Tesseract .traineddata file format standard (version 4 or above). You can find such files commonly on Github.com.

If you wish to train your own custom font support or language pack, we recommend reading our tutorial on creating custom Tesseract language packs.
