When you scan a physical document and save it as PDF, the result is just an image — not real text. You cannot search it, copy from it, or edit it. OCR (Optical Character Recognition) solves this by recognising and extracting all text from the image.
What is OCR and How Does It Work?
OCR software analyses the shapes of characters in an image and converts them to actual text. Modern OCR is highly accurate for printed text — typically 95–99% accuracy for clean documents in good lighting. Handwritten text is less accurate but still useful.

Hindi OCR — Extract Text from Hindi Documents
NextifyTools OCR supports Devanagari script used in Hindi, Marathi, Sanskrit and Nepali. Government documents, Aadhaar cards, legal notices and books in Hindi can all be converted to editable text. The accuracy for printed Hindi text in good lighting is very high.
Tips for Best OCR Accuracy
Use a high-resolution scan (at least 300 DPI). Ensure the document is well-lit with no shadows. Keep the document flat — curved or folded edges reduce accuracy significantly. For photocopied documents, ensure the text is dark and clear.
Frequently Asked Questions
Can OCR extract text from a photo taken on mobile?
Yes. Photos taken with modern smartphones (12MP or higher) usually have enough resolution for good OCR results. Ensure good lighting and a steady hand.
Can OCR extract text from Aadhaar or PAN card?
Yes. OCR works well on Aadhaar and PAN cards. However, always keep original copies safe and be cautious about sharing OCR-extracted personal information.
Does OCR work on handwritten text?
OCR works best on printed text. Handwritten text extraction is partially supported but accuracy varies significantly depending on handwriting clarity.
What languages are supported?
English, Hindi (Devanagari), and many other languages are supported. For best results, select the correct language before running OCR.
