What is preserved
Word to PDF is a free online tool that converts Microsoft Word .docx documents into PDF format entirely inside your browser — no upload, no server, complete privacy. Whether you need to share a report, submit an assignment, archive a contract, or send a resume, converting Word to PDF guarantees your document looks identical on every device and operating system. PDF files are universally supported, cannot be accidentally edited, and are the standard for professional document exchange.
This tool uses mammoth.js, a dedicated Word-to-HTML conversion library, to faithfully reconstruct your document content: headings (H1–H6), paragraphs, bold and italic text, bulleted and numbered lists, tables, embedded images, and font sizes are all preserved. After conversion you get a live, paginated preview rendered using your browser's own layout engine — what you see is exactly what the PDF will contain.
You can customize the output before printing: choose from A4, A3, Letter, or Legal page sizes; switch between portrait and landscape orientation; and select None, Narrow, Normal, or Wide margins. All combinations update the preview in real time so you can verify the layout before committing.
Because everything happens inside the browser using client-side JavaScript, your Word document never leaves your device. There are no file size restrictions imposed by a server upload, no third-party cloud processing, and no risk of your private documents being stored or accessed by anyone else. The tool is completely free — no account, subscription, or registration required.
Typical use cases include converting business reports and proposals to PDF before emailing, preparing resumes and cover letters in PDF format for job applications, archiving contracts and agreements as tamper-evident PDFs, converting academic papers for submission, and batch-processing multiple Word documents for a document management system.
When you drop or select a .docx file, mammoth.js reads the Office Open XML package entirely in memory and converts it to semantic HTML — mapping Word styles to HTML headings, paragraphs, bold, italic, lists, and tables. That HTML is injected into a hidden iframe alongside CSS that simulates the selected page dimensions and margins. The preview iframe renders the result in real time using the browser's layout engine. When you click "Convert to PDF", the tool injects a CSS @page rule specifying the chosen page size and margins, then calls window.print() on the iframe — triggering the browser's native PDF print engine. Selecting "Save as PDF" in the print dialog produces a properly paginated, print-ready PDF file without any server involvement.
