The quickest way: use your document editor's built-in export

Most document editors have a Save As or Export option that lets you turn what you're working on into a PDF without installing anything extra. The exact steps depend on which program you're using, but the principle is the same across Windows, Mac, and Linux.

Open the document you want to save. Go to File in the menu bar, then look for Save As, Export As, or Export to PDF. A dialog box will appear asking where you want to save the file and what to name it. Change the file type dropdown to PDF, pick a location on your computer, give it a filename, and click Save or Export.

This method preserves your formatting — fonts, spacing, images, and page breaks all stay the way you designed them. The PDF will look identical whether someone opens it on Windows, Mac, or a phone.

Key Takeaways

  • Every major document editor (Microsoft Word, Google Docs, LibreOffice) has a built-in PDF export option under File > Save As or File > Export.
  • PDFs lock your formatting in place, so the document looks the same on any device or operating system.
  • Windows 10 and 11 include a built-in PDF printer that works with any program, even ones without native PDF export.
  • If you're converting scanned images or photos to PDF, use a dedicated tool like ImageMagick (command line) or an image editor rather than a document program.
  • PDFs created from your own documents are smaller and cleaner than those made by printing to PDF, because they preserve the original file structure.

How to save as PDF in Microsoft Word

Open your document in Word. Click File in the top left, then select Save As. A sidebar will open on the right side of the screen. Click Browse to choose where to save the file.

In the dialog that opens, type the filename you want. Below the filename field, find the dropdown that says Word Document (.docx) and click it. Scroll down the list until you see PDF, then click it. Choose your folder and click Save. Word will create the PDF in that location.

If you use Word online (through Microsoft 365 in a web browser), the process is slightly different: click File, then read, then read as PDF. The PDF will appear in your Downloads folder.

How to save as PDF in Google Docs

Open your document in Google Docs. Click File at the top left, then hover over read. A submenu will appear. Click PDF Document (.pdf). Your browser will read the PDF to your Downloads folder automatically.

Google Docs PDFs include all your formatting, comments, and tracked changes are not included in the PDF — only the final text and images appear. If you need to preserve comments or revision history, read as a Word document instead and convert that to PDF later.

How to save as PDF in LibreOffice Writer

Open your document in LibreOffice Writer. Click File in the menu bar, then click Export as PDF. A dialog will open with options for compression, security, and other settings. For most documents, the default settings work fine — just click Export.

Choose where to save the file, type a filename, and click Save. LibreOffice will create the PDF. If you want to set a password or restrict printing, you can do that in the export dialog before clicking Export — look for the Security tab.

Using the print-to-PDF method on any program

If your document editor doesn't have a PDF export option, you can use the print dialog instead. This works on Windows, Mac, and Linux with nearly any program.

Open your document. Press Ctrl+P on Windows or Linux, or Command+P on Mac. The print dialog will open. On Windows 10 and 11, look for a dropdown that says Printer and click it. Select Print to File (PDF) or Microsoft Print to PDF. On Mac, look for a PDF dropdown button in the lower left of the dialog and select Save as PDF. On Linux, the option is usually called Print to File and you can select PDF as the format.

Choose where to save the file, type a filename, and click Print or Save. The PDF will be created. This method works with any program — email clients, web browsers, spreadsheets, presentations — but the PDF file is usually larger than one created through native export, because it includes extra formatting data.

When to use PDF export instead of print-to-PDF

Native PDF export (using Save As or Export) creates a cleaner, smaller file because it converts the document directly from its original format. Print-to-PDF simulates printing, which adds extra layers and can make the file size larger.

Use native export whenever your program offers it. Use print-to-PDF only when native export is not available. If you're converting a scanned image, a photo, or a web page, print-to-PDF is often the only practical option — document editors are not designed for images, so use an image editor or a dedicated conversion tool instead.

Checking your PDF after saving

Open the PDF file you just created to make sure it looks right. On Windows, double-click the file and it will open in your default PDF reader. On Mac, the same applies. On Linux, you may need to right-click and select which program to open it with — common choices are Evince, Okular, or Firefox.

Check that all pages are there, text is readable, images are in the right place, and no content got cut off at the edges. If something looks wrong, go back to the original document, fix it, and export to PDF again. Do not try to edit the PDF itself unless you have a PDF editor — most PDF readers are view-only.

Frequently Asked Questions

Can I password-protect a PDF when I save it?

Yes, but only if your document editor offers it. LibreOffice Writer has a Security tab in the export dialog where you can set an owner password (which restricts printing and copying) or a user password (which requires a password to open the file). Microsoft Word does not offer this during export — you would need to use a separate PDF editor afterward. Google Docs does not support password protection at export time.

Why is my PDF file so much larger than the original document?

Print-to-PDF creates larger files than native export because it includes extra formatting data. If you used print-to-PDF, try using your program's native Save As or Export option instead. Embedded images also increase file size — if the PDF contains high-resolution photos, the file will be larger than a text-only document.

Can I convert a PDF back to a Word document?

Yes, but the result depends on how the PDF was created. If it came from a Word document, you can open it in Word and it will usually convert back with most formatting intact. If the PDF is a scanned image or was created from a complex layout, conversion is much harder and you may lose formatting. Online converters exist, but they send your file to a server — if privacy matters to you, use LibreOffice Writer instead, which can open PDFs locally on your computer.

What if the PDF looks different from my original document?

This usually happens because of font differences or page size settings. Check that your document is set to the right page size (usually Letter in the US or A4 elsewhere) before exporting. If you used uncommon fonts, the PDF reader might substitute them with similar ones. To prevent this, use common fonts like Arial, Times New Roman, or Calibri, or embed the fonts during export if your program offers that option.

Can I save multiple documents as PDF at once?

Most document editors do not have a batch export feature. The fastest way is to open each document, export it to PDF, and repeat. If you have many files to convert, command-line tools like LibreOffice's headless mode (on Mac and Linux) or ImageMagick can automate this, but they require typing commands rather than clicking buttons.
