The fastest way: use Word's built-in export

Open your Word document in Microsoft Word (or Word Online). Go to File in the top left, then select Save As. In the dialog that opens, look for the dropdown menu that says "Save as type" — click it and select PDF from the list. Choose where you want to save the file, name it, and click Save. That's it. Your PDF is ready.

This method works the same way in Word 2016, Word 2019, Word 2021, and Microsoft 365. If you're using Word Online (the free version in your browser), the process is nearly identical: click File, then Download, then Download as PDF.

The PDF will look almost exactly like your Word document looked on screen. Fonts stay the same, images stay in place, and page breaks stay where you set them. This is why converting to PDF is useful — it locks the document's appearance so it looks the same whether someone opens it on a Mac, a Windows computer, a phone, or a tablet.

Key Takeaways

  • Word's built-in export (File > Save As > PDF) is the simplest method and requires no extra software.
  • The PDF will preserve your document's formatting, fonts, and layout exactly as it appears in Word.
  • If you don't have Word installed, you can use free online converters like Smallpdf or ILovePDF, though you're uploading your file to someone else's server.
  • PDFs cannot be easily edited in most programs, so save your original Word file if you might need to make changes later.
  • Some features like tracked changes and comments won't appear in the PDF unless you accept or delete them first in Word.

What happens to formatting when you convert

Most of what you see in Word transfers cleanly to PDF. Text, headings, bold and italic formatting, bullet points, numbered lists, images, and tables all move over without problems. Page breaks stay where you put them, and margins remain the same.

A few things don't always translate perfectly. If your Word document uses tracked changes (the feature that shows edits in red), those marks won't show up in the PDF unless you accept or reject them first. Comments and notes in the margins also disappear. Hyperlinks usually work in PDFs, but some complex formatting — like certain text boxes or shapes with special effects — may look slightly different.

If you're converting a document with headers and footers (text that repeats at the top or bottom of every page), those will appear in the PDF. The same goes for page numbers. If your document has a table of contents that uses Word's automatic linking feature, those links usually work in the PDF too.

Using free online converters if you don't have Word

If you don't have Microsoft Word installed, you have options. Smallpdf, ILovePDF, and CloudConvert are three popular free online converters. You upload your Word file to their website, they convert it, and you download the PDF. The process takes a minute or two.

The trade-off is that you're sending your document to someone else's server. If your document contains sensitive information — financial details, medical records, passwords, or anything you wouldn't want stored on the internet — this method isn't the right choice. Read the website's privacy policy first. Most free converters delete files after a few hours, but you're still trusting them to do that.

Google Docs offers another free route if you have a Google account. Upload your Word file to Google Drive, open it in Google Docs, then go to File > Download > PDF Document. Your file never leaves Google's servers (it stays in your own Drive), and the conversion is free.

Why you might want to keep the Word file too

Once you convert a document to PDF, editing it becomes much harder. PDFs are designed to be read and shared, not edited. If someone sends you a PDF and asks you to make changes, you'd normally have to convert it back to Word (which doesn't always work perfectly), make your edits, and send it back.

For this reason, keep your original Word file if there's any chance you'll need to revise the document later. Save the Word version, then create a PDF version from it when you're ready to share or print. That way you have both: an editable version for yourself and a locked version for others.

If you only have the PDF and need to edit it, you can use free tools like Smallpdf's PDF editor or paid software like Adobe Acrobat Pro, but these are workarounds. Starting with the Word file is always easier.

Converting multiple documents at once

If you have several Word files to convert, you don't have to do them one at a time. In Word, you can open each document and export it individually — it only takes a few seconds per file. But if you have dozens of documents, that gets tedious.

Some online converters let you upload multiple files at once. ILovePDF and Smallpdf both have batch conversion options on their free plans. You select several Word files, upload them together, and download all the PDFs in a single zip folder. This saves time if you're converting a whole folder of documents.

If you're on Windows and comfortable with automation, you can also use a tool like XnConvert (free, open-source software) to batch-convert files on your computer without uploading them anywhere. The process requires a bit more setup, but it's useful if you convert documents regularly and want to keep everything local.

Checking your PDF before you share it

After you convert, open the PDF and scroll through it to make sure everything looks right. Check that images are in the right places, that text didn't wrap awkwardly, and that page breaks happened where you expected. Most of the time everything is fine, but occasionally a complex layout can shift slightly.

If something looks wrong, go back to your Word file, fix it there, and export to PDF again. It's much faster than trying to edit the PDF itself. Pay special attention to tables, multi-column layouts, and pages with lots of images — these are the most likely to shift during conversion.

If you're sending the PDF to someone else, consider whether they need to print it. If they do, check how it looks in print preview before you send it. Sometimes a document looks fine on screen but has awkward page breaks or margins when printed.

Frequently Asked Questions

Can I convert a PDF back to Word?

Yes, but it's not perfect. Word can open PDFs directly (File > Open > select your PDF), and it will attempt to convert it back to editable text. However, complex layouts, images, and special formatting often don't convert cleanly. If you need to edit a PDF, it's better to ask for the original Word file if possible.

Will the file size change when I convert to PDF?

Usually the PDF will be smaller than the Word file, especially if your document has lots of images. Word stores extra information about formatting and editing history that PDFs don't need. However, if your Word file is mostly text, the difference might be minimal.

What if my Word document has password protection?

You can still convert it to PDF using the same method. The PDF won't inherit the password protection unless you add it separately. If you want the PDF to be password-protected, you'll need to use a tool like Adobe Acrobat Pro or a free online PDF editor to add password protection after conversion.

Do I need special software to open a PDF after conversion?

No. PDFs open in any web browser (Chrome, Firefox, Safari, Edge) and in most email programs. You don't need to install anything. Windows and Mac both have built-in PDF readers too. This is one reason PDFs are useful for sharing — almost everyone can open them.

Can I convert a Word document with macros to PDF?

Yes, but the macros (automated scripts) won't work in the PDF. Macros are a Word feature and don't transfer to PDF format. If you need the macros to function, keep the Word file. The PDF will contain everything the macros would have produced, but you can't run new macros from the PDF.
