How OCR Works
- Upload a scanned PDF (one with image-based pages).
- Select the document language for best accuracy.
- JustPDF analyzes each page and extracts the text.
- Copy the text or download as a .txt file.
All OCR processing runs in your browser using Tesseract.js. Your documents are never uploaded to any server.
Supported Languages
English, French, German, Spanish, Italian, Portuguese, Dutch, Japanese, Chinese (Simplified), Korean, Arabic, and Russian. More languages can be added on request.
