Frequently Asked Questions
Q. What types of PDFs does this work on?
This tool is designed for scanned image PDFs where text cannot be copied. For text-based PDFs, use a regular text extractor.
Q. What languages are supported?
Korean and English OCR are both supported.
Q. Are PDF files uploaded to a server?
No. PDFs are rendered in the browser with PDF.js and OCR runs locally via Tesseract.js.
