Croatian OCR Guide — Extract Text from Hrvatski PDFs & Images

Croatian documents, whether scanned books, official forms, or historical records, often need to be converted into editable, searchable text. Generic OCR tools trained primarily on English or other major languages can miss the details that make Croatian text accurate and useful.

This guide explains the unique challenges of Croatian OCR and how to extract clean Croatian text from PDFs and images.

Why Croatian OCR Needs Specialized Attention

Croatian uses the Latin alphabet with several letters marked by diacritics.

• The letters č, ć, đ, š, and ž are essential to Croatian and easily missed.
• č vs. ć, and đ vs. dž, can be confused by generic OCR.
• Croatian shares many roots with Serbian and Bosnian, but uses Latin script.
• Mixed Croatian-English documents need accurate language detection.
• Low-quality scans can blur small diacritics.
