How to Convert a Word Document to PDF: Free (Windows, Mac & Phone, 2026)

Converting a Word document to PDF locks in your formatting so it looks identical on every device, prevents accidental edits, and produces the standard format for sharing contracts, resumes, and reports. The best part: you don't need any extra software. Word and your operating system already do it for free. Here's how, on every platform.

Convert Word to PDF on Windows

Microsoft Word has PDF export built in.

1. Open your document in Word.
2. Click File > Save As (or Save a Copy).
3. Choose where to save it.
4. In the Save as type dropdown, select PDF.
5. Click Options if you want to set a page range, include bookmarks from headings, or add accessibility tags.
6. Click Save.

You can also use File > Export > Create PDF/XPS Document, which does the same thing.

Convert Word to PDF on Mac

1. Open the document in Word for Mac.
2. Click File > Save As (or Save a Copy).
3. Click the File Format dropdown at the bottom and choose PDF.
4. Name the file and click Save.

Alternatively, use File > Print, then click the PDF dropdown in the print dialog and choose Save as PDF: this works from almost any Mac app, not just Word.

Convert Word to PDF on iPhone or Android

Using the Microsoft Word mobile app:

1. Open the document.
2. Tap the three-dot menu (or File).
3. Tap Export or Print.
4. Choose PDF and save it to Files or Google Drive.

On iPhone you can also open the print preview, pinch outward on the page, and share the resulting PDF.

Convert Word to PDF Using the Web Version

In Word for the web:

1. Select File > Export.
2. Choose Download as PDF (or Download as PDF with comments to include comments).
3. Confirm the download.

After You've Made the PDF

Once you have your PDF, you'll often want to do a little more with it, and PDF Zone's browser tools handle the next steps for free, with no uploads:

• Shrink it for email: the Compress PDF tool reduces file size so it slips under attachment limits.
• Combine documents: the Merge PDF tool joins your exported file with others into one.
• Sign it: the Sign PDF tool adds your signature without printing.
• Protect it: the Encrypt PDF tool adds a password before you share.

Every one of these runs entirely in your browser, so your document never leaves your device.

Why PDF Instead of Word?

• Consistent formatting: fonts, spacing, and layout stay fixed on any device.
• Harder to edit, recipients can't accidentally change your content.
• Universal. PDFs open everywhere without Microsoft Office installed.
• Professional: the expected format for applications, invoices, and agreements.

Yes. In Word for the web choose Download as PDF with comments, or in desktop Word use the Options button in the Save As dialog to include markup.
