The options give by the previous posters do not always work. The PDF converter does not always convert everything in your document. It has trouble with some fonts and with some equations and so on.
Alternatives include, printing the document and scanning the printed pages to pdf.
Alternatively, you can print the document and file it by mail. If you use ExpressMail by the post office, you get the date you mailed it as the "filing date".
You really need the assistance of a Patent Agent or Patent Attorney. If you are asking this question, the chances are pretty high that you dont know enough to file a successful patent application.
