使用步骤

Drop Your DOCX: Drag your Word document in. DOCX is the modern Word format (from Word 2007+). For legacy .doc files, save them as .docx first in Word — the .doc format isn't supported directly.
Select Output Mode: Choose 'Searchable Text' for selectable text in the output PDF (best for documents you want to search later) or 'Visual Fidelity' for exact Word layout matching (best for designed documents with custom fonts).
Convert Offline: Click 'Convert to PDF'. mammoth.js converts DOCX to HTML in your browser, then html2canvas renders and pdf-lib assembles the PDF. Works offline after page load — disconnect from Wi-Fi and it still works.
Save PDF: Download the resulting PDF. Open in any reader or print directly. The conversion preserved your Word formatting: headings, lists, tables, images, headers/footers. Page size matches your Word document's settings (Letter / A4 / custom).

常见问题

Can I convert DOCX to PDF offline?

Yes. Open our Word to PDF tool, let the page load fully (it caches the conversion libraries), then you can disconnect from the internet. The conversion runs 100% in your browser via mammoth.js, html2canvas, and pdf-lib — no upload, no Microsoft servers, no Adobe servers.

What's the difference between Searchable Text and Visual Fidelity?

Searchable Text mode extracts text from the DOCX and rebuilds a native PDF — perfect for contracts, reports, and text-heavy documents where you'll want to Ctrl+F later. Visual Fidelity mode renders each Word page as an image in the PDF, preserving exact layout — better for designed documents with custom fonts and complex visuals.

Will my Word document be uploaded?

No. mammoth.js processes the DOCX in your browser, html2canvas renders it locally, and pdf-lib assembles the PDF — all client-side. Your document and the result never leave your device. Ideal for confidential contracts, HR records, financial reports, and personal correspondence.

Can it handle tables, images, and headers?

Yes — tables, images, headers, footers, page numbers, and most formatting styles render correctly. Complex multi-column layouts may shift slightly; use the 'Visual Fidelity' mode for designed documents where exact layout matters.

Does it support .doc (older Word format)?

Not directly. .doc is binary and much harder to parse. Open the file in Word and save as .docx (the modern XML-based format), then use our tool. Most users today have .docx because Word has defaulted to it for 17 years.

Will the PDF look the same on Windows and Mac?

Yes — the PDF is the same regardless of platform. The conversion embeds any custom fonts you used (subject to licensing) and renders consistently across Adobe Reader, Preview, Chrome, and other readers. We recommend using 'Searchable Text' mode for documents you'll share widely.
