What is Bengali OCR & Developer API?
Developer API & RAG Docs →Bengali OCR is the automated process of converting scanned multi-page PDFs up to 1GB and documents into editable, searchable Bengali text while preserving accents, complex ligatures, and native character shapes. FastOCR reads printed text in this script and generates full-text searchable PDFs with selectable text overlays at near-instant speed. For engineering teams building RAG pipelines, vector search databases, or automated document ingestion, FastOCR also provides a high-speed Bengali OCR REST API at api.fastocr.org with 10 free pages a month for approved accounts. The API accepts PDF files only.

Why Bengali OCR Is Challenging
- Recognizing complex conjunct consonants (যুক্তাক্ষর) where letters merge and change shapes
- Distinguishing vowel symbols (কার) that appear before, after, above, or below the consonant
- Handling the shirorekha (connecting headline) that runs along the top of Bengali words
- Processing degraded scans or low-contrast photocopies of Bengali publications
- Correctly segmenting words in dense print where characters are close or touching
How to Extract Bengali Text from a PDF & Images
- Go to fastocr.org
- Upload your Bengali image or PDF. Language is detected automatically.
- Wait for processing — images take seconds, PDFs show a progress bar.
- Download results: searchable PDF, raw text file, or copy text directly.
Tips for Better Bengali OCR Accuracy
- Scan at 300 DPI or higher to capture the intricate details of Bengali conjuncts and vowel signs
- Ensure the connecting headline (shirorekha) is clear and not broken by noise or dust
- Verify complex character combinations like ক্ষ, জ্ঞ, ঞ্চ, which are commonly misread
- Use high-contrast inputs to prevent small diacritical dots (like in ড়, ঢ়) from getting lost
Common Use Cases for Bengali OCR
- Digitizing Bengali legal papers, deeds, and land records (Parcha)
- Extracting text from Bangladeshi and Indian government documents, IDs, and certificates
- Converting scanned Bengali books, poetry, and academic publications
- Processing Bengali business invoices, bills, and trade documents
- Archiving historical Bengali literature and newspaper collections
