Convert your .docx documents to PDF in the browser. No upload, no server, simplified formatting.

How Word to PDF works

Word to PDF converts a .docx file to PDF entirely inside your browser using the mammoth library. You drop the file, mammoth parses the OOXML structure and converts the content to HTML, and then the page is printed to PDF using the browser's built-in rendering engine. The conversion is best-effort: straightforward text, headings, lists, tables and basic formatting convert well, but complex layouts may not match exactly. Your document stays on your device throughout and is never sent to a server.

Be honest about what this conversion can and cannot do. Exact font rendering depends on which fonts are available in your browser environment and may differ from Word. Multi-column layouts, precise spacing, footnotes, endnotes, tracked changes, embedded macros and complex tables may render differently or be simplified. If pixel-perfect fidelity to the Word layout is required, exporting from Word directly (File > Save As > PDF) produces a more accurate result. This tool is suited for quick conversions where you need a shareable PDF and do not have Word installed on the current device.

How to use Word to PDF, step by step

  1. Drop your .docx file onto the upload area.
  2. Wait for mammoth to parse the document and generate the PDF preview.
  3. Review the preview to check that the key content looks correct.
  4. Download the PDF.

Common use cases

  • You are on a device without Microsoft Word and need a quick PDF copy of a .docx to share by email.
  • A collaborator sent a .docx and you want to view it as a fixed-layout PDF without installing any software.
  • You need a PDF version of a simple text-heavy document such as a CV or cover letter for online submission.
  • A team member submitted a .docx report and you want a non-editable PDF copy for record-keeping.

Frequently asked questions

Will the PDF look exactly like the original Word document?

Not necessarily. mammoth is designed for best-effort extraction of content rather than pixel-perfect layout replication. Simple documents with standard headings, paragraphs and lists convert well. Complex layouts with multiple columns, custom fonts, precise spacing, footnotes or embedded objects may differ visibly. For exact fidelity, export from Word directly.

Are fonts from my Word document preserved in the PDF?

Font rendering depends on what is available in the browser environment. If a custom font used in the .docx is not installed on the current device, the browser substitutes a fallback font. This can affect how headings and body text appear in the output.

Does my .docx file get uploaded anywhere?

No. mammoth runs as a JavaScript library inside your browser tab. The .docx file is read from your local filesystem into browser memory, parsed and converted to HTML there, and then the browser prints the result to PDF locally. The file content is never transmitted over the network.

What happens to tracked changes, comments and macros?

Tracked changes and comments are not rendered by mammoth; they are stripped from the output. Macros are also not executed or preserved since the conversion targets static content only.

Can I convert a .doc (old Word format) file, not just .docx?

mammoth supports .docx files (Office Open XML format). The older binary .doc format is not supported. If you only have a .doc file, open it in Word or LibreOffice and save it as .docx first, then convert here.

Does the output PDF contain selectable text?

Yes. The conversion goes through HTML, which the browser renders as normal web content before printing to PDF. The resulting PDF contains the text as a proper text layer, not a rasterised image, so text remains selectable and copyable.

Does the converted PDF include a watermark or Sunasty branding?

No. The output contains only the text extracted from your .docx, laid out on plain PDF pages. Nothing is stamped, added or branded.

Can I convert a Word file to PDF on my phone?

Yes. The pipeline (mammoth for parsing, pdf-lib for text layout) runs as plain JavaScript, with no native print dialog involved, so it works the same on a mobile browser as on a computer.
