Free Online Word to PDF Converter

How the Conversion Works

This tool uses mammoth.js, an open-source library that reads the Open XML structure of .docx files and converts them to clean HTML. The HTML is then rendered as a print-ready page, which your browser can export as a PDF using its native print-to-PDF engine.

Because everything runs in JavaScript inside your browser tab, your document is never transmitted anywhere. The tool works fully offline once the page has loaded.

What Gets Converted

• Text formatting — bold, italic, underline, strikethrough
• Headings — H1 through H4 (mapped from Word heading styles)
• Lists — bulleted and numbered, including nested lists
• Tables — preserved with borders and cell alignment
• Hyperlinks — preserved as clickable links in the PDF
• Inline images — extracted and embedded as data URIs
• Blockquotes — from Word's Quote paragraph style

Known Limitations

• Custom fonts — replaced with Times New Roman in the PDF output. This is a browser printing constraint, not a tool limitation.
• Text boxes and shapes — floating text boxes, shapes, and WordArt are not extracted by mammoth.js and will not appear in the output.
• SmartArt and charts — these embedded objects are skipped. Only text content inside them may appear.
• Complex layouts — multi-column layouts and precise absolute positioning are not preserved. The output is a single-column, flow-based layout.
• .doc files — the binary .doc format (Word 97–2003) is not supported. Re-save as .docx first.

Tips for a Better PDF

• Before saving as PDF, check More settings → Background graphics in the Chrome/Edge print dialog to include any shaded table headers.
• Set the paper size to A4 or Letter and margins to Default for best readability.
• If your document has very wide tables, switch the orientation to Landscape in the print dialog.
• For documents with complex formatting, consider using LibreOffice Writer (free, open-source) for a more faithful conversion.
