How to Convert Word to PDF: Free Methods for Every Device

Converting a Word document to PDF locks your layout, fonts and images into a single file that looks the same on every screen and printer, which is why schools, employers and government forms so often ask for a PDF rather than an editable .docx. The good news is that you almost never need to pay for a converter or install anything extra: the ability to turn Word into PDF is built into Microsoft Word, Google Docs, LibreOffice, Apache OpenOffice and even the print menu on your phone. This guide walks through every free method, device by device, and flags the one approach — random online converters — that is worth thinking twice about.

What does converting Word to PDF actually do?

Converting Word to PDF creates a fixed, read-only snapshot of your document in the Portable Document Format. A Word file (.docx or the older .doc) is designed to be edited, so it can reflow and shift depending on the fonts, page size and app the reader uses. A PDF embeds the layout, fonts and images so the page looks identical everywhere, whether it is opened on a Windows laptop, a Mac, a phone or printed out.

That stability is the whole point. When you email a CV, submit an assignment, send an invoice or share a signed form, a PDF stops the other person accidentally editing it and stops your careful formatting from breaking on their machine. The trade-off is that a standard PDF is harder to edit afterwards — so keep your original Word file as the master copy and treat the PDF as the finished, shareable version. If you ever need to go the other way, our guide on how to open a PDF in Word explains what formatting survives the round trip.

Why do people convert Word to PDF?

People convert Word to PDF whenever a document needs to be shared, printed or stored exactly as designed. A few of the most common reasons explain why the format is almost a default for finished documents:

• Job applications. Recruiters and applicant-tracking systems usually prefer a PDF CV, because it opens cleanly on any device and cannot be accidentally altered.
• Assignments and theses. Universities and schools often require submissions as PDF so markers all see identical pagination and formatting.
• Invoices and quotes. A PDF invoice looks professional, prints correctly and cannot be edited by the recipient — important for anything with a legal or financial weight.
• Forms and contracts. PDFs can be signed, locked and, if needed, password-protected, which suits agreements and official paperwork.
• Long-term storage. The PDF/A archival standard is designed to stay readable for decades, so it is the format of choice for records you must keep.

In short, you create a PDF when the content is final and the look matters more than further editing.

How to convert Word to PDF in Microsoft Word

Microsoft Word has built-in PDF export on every modern version, so you do not need a plug-in or an online tool. The exact menu depends on whether you are on Windows, a Mac or the free browser version.

Windows: Save As or Export

On Word for Windows you have two routes that produce the same result. The quickest is File > Save As: choose where to save, open the “Save as type” dropdown, pick PDF, and click Save. The alternative is File > Export > Create PDF/XPS Document > Create PDF/XPS, which opens the same save dialog. Before you save, click Options if you want to export only certain pages, or tick “Document structure tags for accessibility” so screen readers can follow the headings.

There is also a third option that works in any Windows app: press Ctrl + P to open the print dialog and choose Microsoft Print to PDF as the printer. This is handy, but it produces a flatter file with no clickable links or accessibility tags, so prefer Save As or Export for anything you will share widely.

Mac: Save As

On Word for Mac, open File > Save As, set the File Format to PDF, and click Export. You can choose between a file optimised for electronic distribution (smaller) or for printing (higher quality). While macOS also lets you create a PDF from the Command + P print dialog using the PDF menu, Microsoft recommends using Save As on a Mac, because the Print route drops much of the underlying structure that assistive technology relies on.

Word for the web (completely free)

If you do not own a Word licence, the free browser version at office.com converts to PDF too. With the document open, click File > Export and choose Download as PDF. Word for the web gives you a clean PDF, or a version that includes your comments if you need reviewers’ notes preserved. You will need a free Microsoft account and your file stored in OneDrive. For more on what the browser edition can and cannot do, see our overview of Word Online free in New Zealand.

How to convert Word to PDF free with Google Docs

Google Docs is a reliable free converter if you do not have Word installed, and it only needs a browser and a Google account. The steps are:

1. Go to drive.google.com and click New > File upload to upload your .docx file.
2. Double-click the uploaded file, then choose Open with > Google Docs at the top.
3. Click File > Download > PDF Document (.pdf). The PDF saves straight to your device’s downloads folder.

Google Docs handles most everyday layouts — headings, tables, images and page breaks — well, and nothing is installed on your computer. The one caution is that complex Word formatting (custom fonts, advanced text boxes, tracked changes or intricate columns) can shift slightly when the file is converted into Google’s own format first. For a document where exact spacing matters, preview the PDF before sending it. If you also work in the other direction, our guide on converting a PDF to Google Docs covers the reverse task, including scanned files.

How to convert Word to PDF in LibreOffice or OpenOffice

LibreOffice and Apache OpenOffice are free, open-source office suites that open .docx files and export to PDF without any online upload — ideal when the document is private and you want everything to stay on your own machine.

LibreOffice Writer

Open your Word file in LibreOffice Writer, then use one of two options. Click the Export Directly as PDF icon on the toolbar to produce a PDF instantly with default settings, or choose File > Export As > Export as PDF to open the options dialog first. The dialog lets you set the page range, image compression, PDF/A archival format, and even password protection and permissions — useful if you need to stop the PDF being copied or edited.

Apache OpenOffice Writer

Apache OpenOffice works almost identically. Open the document in Writer and either click the Export Directly as PDF toolbar icon for a quick export, or choose File > Export as PDF for the full options dialog. OpenOffice’s PDF dialog has five tabs (General, Initial View, User Interface, Links and Security), so you can export bookmarks from your headings, include or hide comments, and set security options. If you do not already have the suite, our guide to downloading OpenOffice shows the safe, official sources, and our OpenOffice Writer overview explains the rest of the word processor. Because both suites export PDF natively, they are also the simplest way to turn OpenDocument files into PDF — see our dedicated walkthrough on converting ODT to PDF.

How to convert Word to PDF on a phone or tablet

You can convert Word to PDF on a phone without a computer, using either the free Microsoft Word app or the device’s built-in print-to-PDF feature.

iPhone and iPad

If you have the Microsoft Word app, open the document, tap the three-dot menu and look for the Export or Send a Copy option, then choose PDF. If you would rather not install Word, open the .docx in the Files app, tap the Share icon and choose Print; in the print preview, pinch outwards on the page thumbnail to open it as a PDF, then share or save it. Both routes are free and keep the file on your device.

Android

On Android, the free Microsoft Word app can export a PDF from its Share / Export menu. Alternatively, upload the file to the Google Drive app (tap + then Upload), open it, tap the three-dot menu and choose Print, then select Save as PDF as the printer. The PDF is saved to your phone or back to Drive. This print-to-PDF trick works from almost any app that offers a Print option, so it is a dependable fallback even if the app you are using has no obvious “export to PDF” button of its own.

One tip for phones: conversions done entirely through an app or the print menu stay on your device and your own cloud account, so they are safer for personal documents than pasting a file into a web converter in your phone’s browser. If you only ever need occasional conversions, the free Word app plus Print > Save as PDF covers almost every situation without extra downloads.

Converting Word to PDF with online converters: convenient, but mind your privacy

Free web converters such as the many “Word to PDF” sites can be tempting because they need no software, but they come with a real privacy trade-off: you are uploading your document to someone else’s server. For a blank template that is harmless, but for anything containing personal details, financial figures, contracts or client information it is a genuine risk. In New Zealand, businesses handling personal information also have obligations under the Privacy Act 2020, and uploading customer data to an unknown overseas service can sit awkwardly with those duties.

The safest rule is simple: if a document contains sensitive information, convert it offline using Word, LibreOffice or OpenOffice, where the file never leaves your computer. If you do use an online converter, stick to the official tool of a reputable company (for example Adobe’s own Acrobat online tools), check that the page uses an https connection, and prefer services that promise to delete uploaded files automatically after a short period. Avoid converters that bundle downloads, ask you to install a “viewer”, or push you toward a paid plan before they release your file.

Common mistakes when converting Word to PDF

Most PDF conversions go smoothly, but a few recurring errors catch people out. Knowing them in advance saves a round of re-sending files.

• Fonts look wrong in the PDF. This usually happens when a document uses a font the destination device does not have and the font was not embedded. Converting through Word, LibreOffice or OpenOffice embeds fonts automatically; a quick print-to-PDF sometimes does not. Always open the finished PDF and check it before sending.
• Links and bookmarks stop working. The print-to-PDF route (Ctrl+P / Save as PDF) flattens the page, so clickable hyperlinks and heading bookmarks can disappear. Use Save As, Export or Export as PDF to keep them live.
• Tracked changes or comments are exposed. If your document still has tracked changes or reviewer comments, they can carry into the PDF. Accept or reject changes and remove comments first, or use the “clean” PDF option where one is offered.
• The file is huge. High-resolution images can bloat a PDF to many megabytes. Choose the “minimum size / optimised for web” export option, or lower the image compression in the LibreOffice/OpenOffice export dialog.
• Trying to edit the PDF later. A standard PDF is not meant to be re-edited easily. Keep your Word file as the editable master and regenerate the PDF whenever you change the content.
• Uploading private files to unknown websites. As noted above, free online converters receive a full copy of your document. For anything confidential, convert offline instead.

Which method should you use?

The best method depends on what you already have and how sensitive the document is. If you own Microsoft Word, its built-in Save As or Export is the most reliable, because the layout you see is exactly what you get. If you do not have Word, Google Docs and Word for the web convert for free in any browser, which suits quick one-off jobs and Chromebooks. If the document is confidential, or you simply prefer to keep everything offline and free forever, LibreOffice or Apache OpenOffice export to PDF natively with no upload at all. On a phone, the free Word app or your device’s Print > Save as PDF handles it without a computer. For a wider look at the free suites behind several of these methods, compare the options in our guide to LibreOffice versus OpenOffice.

Frequently Asked Questions (FAQ)

Is converting Word to PDF free?

Yes. Every mainstream method is free. Microsoft Word, Google Docs, Word for the web, LibreOffice and Apache OpenOffice all export to PDF at no cost, and both iPhone and Android can save a Word file as a PDF using the free Word app or the built-in print menu. You only pay if you choose a premium online tool, which is rarely necessary.

Does converting to PDF change my formatting?

Exporting directly from Word, LibreOffice or OpenOffice keeps your formatting essentially identical, because the PDF captures the exact page layout. Converting through Google Docs can shift complex layouts slightly, because the file is first translated into Google’s own format. Whichever method you use, open the finished PDF and check it before you send it.

Can I convert a PDF back into an editable Word document?

Yes, though results vary. Microsoft Word can open many PDFs and convert them to editable text, and Google Docs can do the same, including running text recognition on scanned pages. Simple text-based PDFs convert well, while heavily designed or scanned documents may need tidying up afterwards.

How do I convert Word to PDF without any software?

Use a browser-based tool. Upload your file to Google Drive, open it with Google Docs and choose File > Download > PDF Document, or use the free Word for the web and pick File > Export > Download as PDF. Both need only a free account and work on any computer, including Chromebooks.

Are free online Word-to-PDF converters safe?

They are fine for non-sensitive files, but every online converter uploads a full copy of your document to its servers. For anything containing personal, financial or confidential information, convert offline in Word, LibreOffice or OpenOffice instead. If you must use a web tool, choose a reputable provider, check for an https connection and confirm it deletes uploaded files promptly.
