Hi dionel33514362,
You can use either Adobe PDF Pack or Acrobat to convert Word documents to PDF.
Adobe PDF Pack is an online service, which allows you to upload files and convert them to PDF via a web interface.
See Acrobat Help | Create PDFs with Acrobat for information about creating PDF files in Acrobat. If you don't have Acrobat, please feel free to give it a try. You can download the free 30-day trial from the Acrobat link I mentioned above.
Please let us know if you have additional questions.
Best,
Sara
