Free Word to PDF Converter
Convert Word documents (.docx) to PDF right in your browser. Upload your .docx file, preview the content, then download the PDF. The converter re-typesets your document's text — headings, bold, italic, lists, and tables — in a clean print layout; it does not reproduce the original fonts, colors, or embedded images. All processing happens entirely in your browser — your document never leaves your device. Works for letters, reports, CVs, proposals, and any text-focused Word document.

Frequently Asked Questions
Is my Word document uploaded to a server?+
No. Your .docx file is processed entirely in your browser using the File API and JSZip to read the document structure. Nothing is sent to any server. Close the tab and your document is gone.
What formatting is preserved?+
The converter keeps your document's structure — headings (Heading 1–6), paragraphs, bold, italic, underline, bulleted lists, numbered lists, and basic tables — and re-typesets it in a clean print layout. It does not preserve the original fonts, colors, or embedded images, and complex formatting like tracked changes, embedded objects, text boxes, and watermarks will not render.
Why does the output look different from Microsoft Word?+
This tool re-typesets your text rather than replicating Word's rendering engine, so the PDF uses a standard print font and layout instead of your document's original fonts and colors, and images are omitted. For a pixel-perfect copy, use Word's built-in Save As PDF, or Google Docs.
What file types are supported?+
Only .docx format (Office 2007 and later). Legacy .doc files are not supported — open your .doc in Word and Save As .docx first.
Is there a file size limit?+
No server-side limit since everything runs in your browser. Very large files (>20 MB) may be slow depending on your device, but most Word documents are well under 5 MB.

How Word to PDF Conversion Works in Your Browser
A .docx file is not a single document — it is a ZIP archive containing a set of XML files. The main content lives in word/document.xml, styles in word/styles.xml, and images in the word/media/ folder. This tool uses JSZip (a browser-compatible ZIP library) to unpack the archive and extract the document XML directly in your browser, with no data ever leaving your device.
What formatting is preserved
The converter handles the most common formatting elements: headings (Heading 1 through Heading 6), body paragraphs, bold, italic, underline, strikethrough, bulleted and numbered lists, text alignment (left, center, right), hyperlinks, and basic tables. These cover the vast majority of real-world Word documents — letters, reports, proposals, and CVs.
What may not convert perfectly
Word has hundreds of formatting options beyond what any browser-based converter can replicate. Features that may not render correctly include: multiple columns, text boxes and shapes, floating images, headers and footers, tracked changes, comments, fields (like automatic page numbers and TOCs), embedded Excel charts, and complex table cell borders. For documents relying heavily on these features, use Microsoft Word's native Save As PDF or print through Google Docs for best results.
Why the PDF uses browser print
When you click Download PDF, the tool opens a clean print-optimised version of your document in a new window and triggers the browser's print dialog. This approach produces genuine vector-text PDFs — your text is selectable and searchable, unlike image-based converters that capture a screenshot of the document. The print engine in Chrome, Edge, and Firefox produces high-quality PDF output that renders correctly at any zoom level.
