Word to PDF Converter

Convert .docx files to PDF entirely in your browser. Preserves headings, paragraphs, lists, tables, bold/italic and images. Files never leave your device.

PDF Tools

Headings, paragraphs, lists, tables, bold/italic and embedded images are preserved. Page headers/footers, page numbers, footnotes, and SmartArt are not - use Word's own "Save As PDF" for documents that depend on those.

About the Word to PDF Converter

The Word to PDF Converter turns a .docx file into a clean PDF that you can share, print, or archive. Headings render at the right size, lists keep their bullets, tables stay structured, and basic formatting like bold, italic, and links survive the conversion.

The tool uses the same .docx parser that GitHub, Confluence, and other Word-import services use under the hood. Conversion runs entirely in your browser - your file never reaches a server. This makes it safe for confidential drafts, NDAs, internal reports, and anything else you would not paste into a random web form.

Common use cases

  • Send a Word draft to someone who does not have Word installed
  • Lock down a contract or report before sharing
  • Archive Word documents in a format that does not change between Office versions
  • Prepare documents for print where Word's layout would not be portable

Tips for best results

For best results, use a recent .docx file (Word 2007 or later). Older .doc files need to be saved as .docx in Word first. Complex layouts - multi-column pages, headers/footers, footnotes, page numbers, and embedded objects (charts, equations, smart art) - may not survive the conversion perfectly because they rely on Word-specific layout features. For documents like that, save as PDF directly from Word for highest fidelity.

Privacy & data handling

The Word to PDF Converter runs entirely in your browser. The .docx or .xlsx file you upload is parsed locally on your device - nothing is uploaded, logged, or shared with any server. Files are released from memory the moment you close the tab. No signup, no daily limit, no watermarks.

What formatting is preserved?
Headings (H1-H6) with the right size, paragraphs, bold and italic, numbered and bulleted lists (including nested), tables with cell borders, hyperlinks, blockquotes, and images embedded in the document. Most documents come through cleanly.
What gets lost in conversion?
Page-level layout features: headers and footers, page numbers, footnotes/endnotes, tracked changes, comments, drawing canvas content, embedded SmartArt or Excel objects, and exact font matching. Complex multi-column layouts may flow as a single column. For perfect fidelity, use Word's own File → Save As PDF.
Is my Word document uploaded anywhere?
No. The mammoth.js parser runs in your browser. You can verify by opening DevTools → Network tab during conversion - you will see zero requests to our server related to the file. Files are released from memory when you close the tab.
What file size can I convert?
Comfortable up to ~50 MB. Larger files (200 MB+) may slow the browser. Very long documents (500+ pages) work but the rendering pass takes longer. If memory becomes an issue, split the document in Word first and convert each part.
Can I convert .doc (old Word format)?
Not directly - .doc is a binary format that needs Word or a server-side tool to read. Open the .doc in Word (or Google Docs / LibreOffice) and "Save As" → .docx, then convert here. The save-as is free and quick.
