Hindi OCR — Extract Hindi Text from Images and PDFs

Why Hindi OCR Is Challenging

• Recognizing Devanagari conjunct consonants (संयुक्त अक्षर) where two or more consonants merge into a single glyph
• Handling the shirorekha (headline) — the continuous horizontal line connecting Devanagari characters
• Distinguishing vowel matras (diacritical marks) that attach above, below, or beside consonants
• Processing documents mixing Hindi Devanagari with English Latin text and Arabic numerals
• Correctly recognizing half-forms of consonants and nukta dots that modify characters
• Handling varied Devanagari fonts where character shapes differ significantly between typefaces

How to Extract Hindi Text (Step by Step)

1. Go to fastocr.org
2. Upload your Hindi 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 Hindi OCR Accuracy

1. Use 300 DPI scans to preserve the shirorekha line and fine matra details in Devanagari
2. Ensure the horizontal headline connecting characters is not broken by scan artifacts
3. For mixed Hindi-English documents, verify that script switching is handled correctly
4. Check conjunct consonants carefully — they are the most common source of Hindi OCR errors
5. Avoid low-contrast scans where matras above and below characters may be lost
