No upload, no sign-up; scans (no OCR) and password-protected files are declined, and layout is not preserved.Extract 텍스트 from PDFExtract the text out of a PDF in one tab: click or drop your file and pdf.js pulls every selectable line locally — the document itself never leaves your machine. Per-page failures degrade to a placeholder instead of killing the run.PDF 텍스트 추출기A local PDF text extractor: open the file with the pdf.js engine right in this page, copy the plain text or download it as .txt, with page/word/character counts shown up front.

Fonts, images and page layout from the original are not carried across (this is an honest text rebuild), scans get no OCR, and password-protected PDFs are declined.PDF to DOCX 변환기Turn a PDF into a .docx you can keep editing: the text is extracted locally with the same pdf.js engine as our PDF text tools and rebuilt as clean Word paragraphs with the same builder as our Text to Word page. Reflowed plain text on purpose — not a pixel-faithful conversion; dense scans (no OCR), encrypted files and documents past the size gates are declined honestly, and nothing is ever uploaded.
