How to Convert a Word Document to PDF for Free

· 6 min read

Quick summary: To convert a Word document to PDF for free, open it in Microsoft Word and go to File → Save As (or Export) → choose PDF as the format → Save. On Mac or Windows, this is built into Word at no extra cost. Without Word, upload the .docx to Google Docs and use File → Download → PDF, or open it in the free LibreOffice Writer and use File → Export as PDF.

Converting a Word document to PDF locks in the formatting so it looks identical on every device and printer — the recipient does not need Word installed to view it. Every major method below is free. You can also upload the resulting PDF to our free AI PDF reader to summarize it or ask questions about the content.

How to convert Word to PDF in Microsoft Word (Windows)

  1. Open the document in Microsoft Word.
  2. Go to File → Save As (or File → Export → Create PDF/XPS).
  3. Choose a location, then set Save as type to PDF.
  4. Click Save (or Publish).

Optimize for smaller size: In the Save As dialog, choose “Minimum size (publishing online)” instead of “Standard” to produce a smaller PDF — useful for emailing.

How to convert Word to PDF in Microsoft Word (Mac)

  1. Open the document in Word for Mac.
  2. Go to File → Save As.
  3. In the File Format dropdown, select PDF.
  4. Click Export.

Alternative — Print to PDF: File → Print → click the PDF dropdown at the bottom left → “Save as PDF”. This works even in older Word versions.

How to convert Word to PDF without Microsoft Word (free)

Google Docs (any platform)

  1. Go to drive.google.com → ”+ New” → File upload → select your .docx file.
  2. Right-click the uploaded file → “Open with” → “Google Docs”.
  3. Google converts it to an editable Google Doc automatically.
  4. Go to File → Download → PDF Document (.pdf).

Formatting (fonts, spacing, images) usually carries over well, though complex layouts with tables or text boxes may shift slightly.

LibreOffice Writer (free, open-source)

  1. Download LibreOffice (libreoffice.org) — free for Mac, Windows, and Linux.
  2. Open the .docx file in LibreOffice Writer.
  3. Go to File → Export As → Export as PDF.
  4. Adjust settings if needed (image compression, PDF/A) and click Export.

LibreOffice reads .docx files natively and generally preserves formatting closely.

Microsoft Word Online (free with a Microsoft account)

  1. Go to office.com and sign in with a free Microsoft account.
  2. Upload the .docx to OneDrive, or open it directly in Word Online.
  3. Go to File → Save As → Download as PDF.

No paid Microsoft 365 subscription required — Word Online’s core editing and export features are free.

How to convert Word to PDF on iPhone or Android

Google Docs app

  1. Open the Google Docs app and open or upload the Word file.
  2. Tap the three-dot menu → “Share & export” → “Save as”.
  3. Choose PDF document → save to your device or cloud storage.

Microsoft Word app (free, view and export)

  1. Open the Word app and open the document.
  2. Tap the three-dot menu → “Save As”.
  3. Change the file type to PDF and save.

The mobile Word app is free for viewing and basic exporting; editing on small screens (under 10.1”) does not require a subscription either.

All the methods above preserve clickable hyperlinks, bookmarks generated from headings, and most formatting. To double-check after converting:

  1. Open the resulting PDF.
  2. Click a hyperlink to confirm it navigates correctly.
  3. Check the table of contents (if any) — Word headings typically convert to PDF structural bookmarks automatically. See how to bookmark a PDF for free to view or add more.

How to batch-convert multiple Word documents to PDF

Windows: PowerShell + Word

For converting many files at once, a short PowerShell script driving Word’s “Save As PDF” automation can loop through a folder — search “PowerShell batch convert docx to pdf” for ready-made scripts if you’re comfortable running one.

Mac: Automator

  1. Open Automator → create a new Quick Action (or Application).
  2. Add the “Change Type of Images”… actually, use “Print Finder Items” with a PDF-only printer preset, or use a Run Shell Script action calling textutil (built into macOS) for .doc/.rtf files: 
    for f in *.doc; do textutil -convert pdf "$f"; done
    Note: textutil handles .doc, .rtf, and .txt well but has limited .docx support — for .docx files, batch conversion is more reliable through Word or LibreOffice’s command-line mode (soffice --headless --convert-to pdf *.docx).

Frequently Asked Questions (FAQ)

Does converting Word to PDF change the formatting?

Generally no — fonts, images, tables, and layout are preserved almost exactly, since PDF is designed to lock in a fixed visual layout. Minor differences can appear with unusual fonts not embedded in the document or very complex table layouts.

Can I convert a Word document to PDF without installing anything?

Yes — Google Docs (upload and download as PDF) and Word Online both work entirely in a browser with no software install, using only a free account.

Why is my PDF missing images after converting from Word?

This usually happens with linked images (inserted by reference to a file path) rather than embedded images. Re-insert the images directly (Insert → Pictures → This Device) rather than linking to them, then convert again.

How do I convert Word to PDF and keep it editable later?

Keep the original .docx file — a PDF is not meant to be re-edited as a document. If you need to edit content that only exists in a PDF, see how to edit a PDF for free for markup and text-overlay methods.

Can I password-protect the PDF while converting from Word?

In Word for Mac/Windows, click “Options” in the Save As / Export dialog to add a password directly during the PDF export. Otherwise, convert first and then see how to password protect a PDF for free.
