OCR (Optical Character Recognition) is technology that recognizes text in images and scanned documents. Our tool uses Tesseract.js, an open-source OCR engine that runs entirely in your browser — no server processing required.
The tool supports scanned PDF files and common image formats including JPG, PNG, and TIFF. For best results, use high-resolution scans (300 DPI or higher).
Accuracy depends on the quality of the scan and the clarity of the text. Clean, high-resolution scans of printed text typically achieve 95%+ accuracy. Handwritten text or low-quality scans may have lower accuracy.
Yes. All OCR processing happens entirely in your browser using Tesseract.js WebAssembly. Your document is never uploaded to any server.
