There are many word to pdf converters free online or for downloading, convertword2pdf.com is a freeware online and simpo pdf creator lite is a free pdf creator for downloading.
But you don't need these software if you are using office 2007 and above.
For office 2007, you can download a 'save as PDF/XPS' add-in from Microsoft website, then save your word to pdf format as below steps;
If office 2010 used, this add-in is built in the office suite, no need to download it, just save the word document directly to pdf, open the office file -> go to share -> select create PDF/XPS document.
If you are using office 2003, no add-in can be used, you need support of third-party software like simpo pdf creator or online word to pdf converter.
