Modufile's PDF to Word converter extracts text from your PDF using the MuPDF engine and generates an editable .docx file using the docx library. It analyzes font size data to detect headings and preserves basic paragraph structure. This tool works best with text-heavy, single-column PDFs. Complex layouts with tables, multi-column text, or heavy formatting may require manual adjustment after conversion. Since both MuPDF and the docx generator run in your browser via WebAssembly and JavaScript, your files are never uploaded to a server — unlike most online PDF to Word converters.
