Bulgarian OCR Guide — Extract Text from Български PDFs & Images

Bulgarian 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 Bulgarian text accurate and useful.

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

Why Bulgarian OCR Needs Specialized Attention

Bulgarian uses the Cyrillic script with letters that can look like Latin or Russian analogs.

• Bulgarian Cyrillic has letters not present in Russian, such as ъ, ѝ, and the commonly omitted ь.
• Handwritten and cursive Bulgarian forms can be ambiguous.
• Latin lookalikes like a, e, o can be confused with Cyrillic а, е, о.
• Bulgarian has its own orthographic and punctuation rules.
• Mixed Bulgarian-English documents need careful handling.
