How to Convert Word to PDF for Free: Every Method Compared

There are more ways to turn a .docx into a PDF than most people realize — some already sitting on your computer, some free online, and at least one that quietly costs you your formatting. Here's how they actually compare.

"Convert Word to PDF" sounds like a solved problem, and mostly it is — but the method you pick genuinely changes the result. Some tools reproduce your document's layout faithfully because they use the same rendering logic Word itself relies on for printing. Others approximate it, which is fine for a simple memo and risky for anything with tables, custom fonts, or a specific page layout you care about.

Word's own "Save As PDF" or "Export"

If you already have Microsoft Word open, this is the most direct option: File > Save As (or Export) > PDF. Because it's Word doing the exporting, using its own print engine, this is about as faithful a conversion as you can get — fonts, tables, headers and page breaks come out exactly as they appear on screen. The catch is obvious: you need a licensed copy of Word installed, which not everyone has, especially on a shared or public computer.

Google Docs' free "Download as PDF"

If you don't have Word but do have a Google account, you can upload a .docx to Google Drive, open it in Google Docs, and use File > Download > PDF. It's free and doesn't require installing anything. The tradeoff is that Google Docs isn't Word — it uses its own layout engine to interpret the .docx, which occasionally reflows complex formatting differently, especially with custom fonts, unusual table structures, or precise pixel-level layouts. For a straightforward text document it's usually fine; for a carefully designed one, it's worth double-checking the result before you send it anywhere.

LibreOffice (free desktop software)

LibreOffice is a free, open-source office suite that opens .docx files and exports to PDF from its own File menu, no account required. It's a solid option if you'd rather not touch a cloud service at all, and its layout engine is generally good at reproducing Word documents accurately. The downside is the same as Word itself: it's desktop software you have to install first, which is overkill if you just need to convert one file right now.

A browser-based converter

The fastest option when you don't have Word installed and don't want to sign into anything: a free online Word to PDF converter that runs entirely in the browser. Drop the .docx in, and it comes back as a PDF in seconds, with no account and nothing left behind on a server afterward. The thing to check with any online converter is what it actually does with your file while converting it — see our guide to document security basics if you're converting anything sensitive.

The Mac "Print to PDF" trick

On a Mac, if you can open a document in any app at all — Pages, Word, even a browser-based viewer — the system-wide Print dialog has a "Save as PDF" option in the PDF dropdown at the bottom left. It's a print operation rather than a true document export, so it's reliable for straightforward layouts but can occasionally miss things that only exist for editing, like tracked changes formatting.

Which method actually preserves formatting best

In practice, it comes down to how closely the tool's underlying rendering matches Word's own. That's exactly what separates a conversion that looks right from one that doesn't — we cover it in more detail in what actually happens when you convert Word to PDF. If a document has anything beyond plain paragraphs — tables, columns, embedded images, non-standard fonts — it's worth converting once and actually checking the result rather than assuming it's fine, whichever method you use. Our formatting troubleshooting guide covers the specific things to look for.
