There are no Word tools on this site yet, so this page is not in the sitemap. These are the quickest ways to do the common jobs today.
In Word, choose File › Save As › PDF (or Export › Create PDF). In Google Docs use File › Download › PDF document. In any other editor, print and pick Save as PDF as the printer.
Recent versions of Word can open a PDF directly (File › Open) and convert it into an editable document. Complex layouts and scanned pages may not convert cleanly, and we do not offer a converter here because it cannot be done reliably inside a browser without uploading your file.
