How to Convert Word to PDF Without Microsoft Office

Why convert Word to PDF?

PDF is the universal format for sharing documents. Unlike .docx files, PDFs look identical on every device and operating system — fonts, layout, and formatting are locked in. If you're submitting a CV, sending a contract, or sharing a report, PDF is almost always the right choice.

Method 1: Use Signvert's free browser tool (no account needed)

The fastest method with no software required:

1. Go to signvert.com/tools/word-to-pdf.
2. Drop your .docx file onto the page or click "Choose .docx file".
3. A live preview of your document appears. Check the content looks correct.
4. Click "Convert to PDF" and download the result.

Your file never leaves your device. The conversion runs entirely in your browser using open-source libraries.

Method 2: Google Docs (free, requires Google account)

1. Go to docs.google.com and sign in.
2. Click "File" → "Open" → "Upload" and select your .docx file.
3. Once open, click "File" → "Download" → "PDF Document (.pdf)".

This method preserves formatting well but requires a Google account and uploads your document to Google's servers.

Method 3: LibreOffice (free desktop software)

LibreOffice Writer is a free, open-source alternative to Microsoft Word. Open your .docx file, then go to "File" → "Export as PDF". This gives you the most control over PDF settings but requires installing software.

Which method preserves formatting best?

For simple documents (letters, CVs, reports), all three methods produce good results. For complex layouts with tables, columns, or custom fonts, LibreOffice or Google Docs tend to be more faithful. The browser-based method is best for speed and privacy.

What about .doc files (older Word format)?

The Signvert browser tool currently supports .docx (Word 2007 and later). For older .doc files, open them in Google Docs or LibreOffice first, save as .docx, then convert.
