On Windows you can also use File → Print → Microsoft Print to PDF for the same result.

Method 3: Google Docs (Free, No Software)

If you don't have Microsoft Word, Google Docs is an excellent free option — though it requires uploading your document to Google's servers.

Note: Google Docs may slightly alter the formatting of complex documents. It works well for text-heavy files but may struggle with precise table layouts.

LibreOffice is a free, open-source office suite that handles .docx files well and exports clean PDFs. No account required.

1. 1Download LibreOffice from libreoffice.org (free)

• Have Microsoft Word installed: use Word's built-in Save As PDF — most accurate for complex layouts
