Bengali OCR — Image to Text & PDF

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

1. Go to fastocr.org
2. Upload your Bengali image or PDF. Language is detected automatically.
3. Wait for processing — images take seconds, PDFs show a progress bar.
4. Download results: searchable PDF, raw text file, or copy text directly.

Tips for Better Bengali OCR Accuracy

1. Scan at 300 DPI or higher to capture the intricate details of Bengali conjuncts and vowel signs
2. Ensure the connecting headline (shirorekha) is clear and not broken by noise or dust
3. Verify complex character combinations like ক্ষ, জ্ঞ, ঞ্চ, which are commonly misread
4. Use high-contrast inputs to prevent small diacritical dots (like in ড়, ঢ়) from getting lost
