Frequently Asked Questions

Does this work on scanned documents that are just photos of text?▼

This tool reads text layers that are already embedded in a PDF using the pdf.js engine, so it works best on PDFs that already contain real text. A pure image-only scan with no text layer needs full optical character recognition, which requires server-side processing (like Tesseract OCR) rather than the in-browser extraction this tool performs.

How do I know if my PDF already has a text layer?▼

Try selecting or highlighting text on the page in a normal PDF viewer — if you can select individual words, there's a text layer present and this tool will extract it cleanly.

어떤 출력 형식을 선택할 수 있나요?▼

Pick a searchable PDF if you want to keep the original look while making the content selectable and searchable, or a plain text file if you just need the raw words to paste elsewhere.

손으로 쓴 메모도 처리되나요?▼

아니요, 이 도구는 이미지 기반 문자 인식을 수행하는 대신 기존 디지털 텍스트 레이어를 추출하므로 필기 내용을 읽을 수 없습니다.

Is my document processed on your servers?▼

아니요, 텍스트 추출은 pdf.js를 사용하여 브라우저 내에서 전적으로 이루어지므로 문서 내용이 어디에도 업로드되지 않습니다.
