How OCR Works — Extract Text from Scanned Documents

OCR (Optical Character Recognition) analyses images of text and converts them into machine-readable characters. CuroPDF uses Tesseract.js — a WebAssembly port of Google's Tesseract OCR engine — running entirely in your browser.

Accuracy depends on document quality

Clean printed text at 300 DPI+ — 90–97% accuracy
Good phone photo — 75–90% accuracy
Low-resolution or faded print — 50–75% accuracy
Handwriting — 20–50% accuracy (printed letters better than cursive)

✅ For best results: good lighting, no shadows, flat surface, camera directly above the document. 300 DPI or higher for scanned documents.

Supported languages

English, French, German, Spanish, Italian, Portuguese, Chinese (Simplified), Arabic, Russian and Japanese. Always select the correct language — the wrong language setting significantly reduces accuracy.
