PDF OCR Converter

Upload a PDF: extract the text layer when present, OCR scanned pages with Tesseract (Chinese/English/mixed), merge the text and export TXT. The PDF is not uploaded; the first OCR downloads language data from a CDN. Always proofread OCR output, especially amounts/dates/IDs.

OCR languageMax pages

Extracts the PDF text layer first; scanned pages use Tesseract OCR. The first run downloads language data.

Extracted text

All processing is local; Tesseract/PDF.js load from a CDN, but the PDF is not uploaded. OCR accuracy depends on scan quality/language/layout.

Only process files you have rights to; evaluate CDN dependencies/local environment for sensitive files.
