소개 PDF OCR 온라인 - 스캔된 PDF에서 텍스트 추출

For scanned PDFs or image-based documents, standard text extraction doesn't work. This tool uses Tesseract.js (open-source OCR engine) loaded from CDN to recognize text in images. Upload a scanned PDF or an image file (JPEG, PNG, TIFF). The tool renders each PDF page at 2.5× scale for accuracy, then runs OCR on each one. Supports 12 languages including English, French, Spanish, German, Hindi, Arabic, Chinese, Japanese, and more. Shows a confidence score per page and lets you download the extracted text.
