How to Convert Word to PDF

Tools mentioned in this guide

Converting a Word document to PDF is one of the most common file tasks — whether you're sending a resume, sharing a report, or submitting a form. PDFs preserve your formatting exactly as intended, no matter what device or operating system the recipient uses.

This guide walks you through every method available, from browser-based converters to built-in desktop options, so you can pick the fastest approach for your situation.

Why Convert Word to PDF?

Word documents (.docx or .doc) look different depending on the software and OS used to open them. Fonts shift, spacing breaks, tables collapse. PDF is a fixed format — it looks identical everywhere. That's why contracts, invoices, resumes, and official documents are almost always sent as PDFs.

  • Universal compatibility — opens on any device without Word installed
  • Preserved formatting — fonts, layouts, tables, and images stay exactly as designed
  • Smaller file size — PDFs are typically smaller than Word files
  • Hard to accidentally edit — recipients can read but not change the content (unless they have a PDF editor)
  • Professional standard — expected format for CVs, contracts, applications, and reports

Method 1: Use FileNaut (Browser — No Software Needed)

FileNaut's Word to PDF converter runs entirely in your browser. Your file never leaves your device — nothing is uploaded to any server.

  1. Go to filenaut.com/word-to-pdf
  2. Click Choose File or drag and drop your .docx file onto the upload area
  3. Your document renders in the preview panel — verify it looks correct
  4. Click Convert to PDF
  5. Your browser's print dialog opens — select Save as PDF as the destination
  6. Uncheck Headers and footers in the print dialog (to avoid page URLs appearing in the output)
  7. Click Save and choose where to save your PDF

Tip: This method uses your browser's own print engine, which produces clean, selectable-text PDFs with accurate page breaks — no image-based compression or font substitution.

Limitation: Legacy .doc files (Word 97–2003 format) are not supported client-side. Convert to .docx first using Microsoft Word or LibreOffice, then use FileNaut.

Method 2: Save as PDF Directly in Microsoft Word

If you have Microsoft Word installed, this is the fastest method and produces the highest-fidelity output.

On Windows:

  1. Open your document in Word
  2. Click File → Save As
  3. Under Save as type, select PDF (*.pdf)
  4. Choose a location and click Save

Alternatively: File → Export → Create PDF/XPS Document → Publish

On Mac:

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

Pro tip: In the Save As dialog on Windows, click Options to control which pages to include, whether to embed fonts, and whether to optimize for print or screen.

Method 3: Print to PDF (Works on Any App)

Every major operating system has a built-in "Print to PDF" capability that works from any application — Word, LibreOffice, Google Docs, or anything else.

Windows (Microsoft Print to PDF):

  1. Open your file in any program
  2. Press Ctrl + P
  3. Under Printer, select Microsoft Print to PDF
  4. Click Print
  5. Choose a save location and filename

Mac (Save as PDF from Print Dialog):

  1. Open your file and press Cmd + P
  2. Click PDF in the bottom-left of the print dialog
  3. Select Save as PDF
  4. Name your file and click Save

Method 4: Google Docs (Cloud, Free)

If you don't have Word installed, Google Docs is a reliable free alternative.

  1. Go to docs.google.com
  2. Upload your .docx file: click the folder icon → Upload
  3. Open the file in Google Docs
  4. Click File → Download → PDF Document (.pdf)

Note: Google Docs may slightly reformat complex layouts (custom fonts, text boxes, complex tables). For critical documents, always review the PDF before sending.

Method 5: LibreOffice (Free Desktop Software)

LibreOffice is a free, open-source alternative to Microsoft Office that handles Word documents well.

  1. Download LibreOffice from libreoffice.org
  2. Open your .docx file in LibreOffice Writer
  3. Click File → Export as PDF
  4. Adjust settings (image quality, password protection, etc.) and click Export

LibreOffice also supports batch conversion from the command line:

libreoffice --headless --convert-to pdf document.docx

Common Problems & Fixes

Fonts look wrong in the PDF

The font used in your Word document isn't installed on the converting machine. Fix: embed fonts in the Word file before converting (File → Options → Save → Embed fonts in the file on Windows), or use common system fonts like Arial, Times New Roman, or Calibri.

Images are blurry

Many converters compress images by default. In Word, choose Optimize for: Print (not Minimum size) when exporting. In LibreOffice, set image quality to 90%+ in the PDF export dialog.

Tables are missing or misaligned

Complex nested tables sometimes break in non-Word converters. If possible, simplify the table structure in Word first, then convert.

PDF has incorrect page numbers in header/footer

When using browser-based Print to PDF, uncheck Headers and footers in the print dialog before saving.

The .doc file won't convert

Legacy .doc format (Word 97–2003) isn't supported by most browser-based tools. Open it in Word or LibreOffice and re-save as .docx first.

Frequently Asked Questions

Is it safe to convert Word to PDF online?
With FileNaut, yes — your file never leaves your browser. The conversion happens entirely on your device using client-side JavaScript. No file is uploaded to any server, so there's no privacy risk. For other online converters that do upload files, always check their privacy policy — sensitive documents like contracts or CVs should never be uploaded to untrusted services.
Will the PDF look exactly like my Word document?
If you convert using Microsoft Word itself (Save As PDF) or FileNaut's browser-based tool, formatting is preserved very accurately. Google Docs and LibreOffice may introduce minor differences in custom fonts, line spacing, or text box positions — especially with complex layouts. For critical documents, always review the PDF on the final page before sending.
Can I convert a Word document to PDF on iPhone or Android?
Yes. On iPhone, open your .docx in the Files app or Word mobile, then share → Print → tap the PDF preview and choose Save to Files. On Android, open it in Google Docs, then File → Download → PDF. You can also use FileNaut on mobile — it works in any mobile browser.
Does converting Word to PDF reduce file size?
Usually yes — a Word document with embedded images and fonts can be several MB, while the equivalent PDF is often 30–50% smaller. However, a PDF with very high-resolution images can sometimes be larger. If file size matters, choose "Optimize for screen" or "Minimum file size" in the Word export options.
Can I password-protect a PDF after converting?
Yes. In Microsoft Word, click File → Save As → PDF → Options and check "Encrypt the document with a password". In LibreOffice, the PDF Export dialog has a Security tab. You can also add a password to an existing PDF using FileNaut's PDF tools or other PDF editors after conversion.
What's the difference between .doc and .docx?
.docx is the modern Word format (XML-based, introduced in Office 2007). .doc is the legacy binary format from Word 97–2003. Most converters — including FileNaut — support .docx only. If you have a .doc file, open it in Word or LibreOffice and save it as .docx before converting.
Can I convert multiple Word files to PDF at once?
Batch conversion isn't available in free tiers of most browser tools. In Microsoft Word, you can use a macro or the LibreOffice CLI to convert multiple files at once. FileNaut Premium will support batch processing as a feature in a future update.
