While there are a number of PDF writers like CutePDF and Doro that can easily convert any type of document in PDF format from virtually any Windows application, you can easily convert any Microsoft Word document to PDF format using a built-in option. This feature is available in both MS Word 2013 and 2010.
Saving Files To PDF Format using Microsoft Word 2013
To save a MS Word file in PDF format, simply go to the File menu, click Save As and select a location to save the document.
This will display a window from where you can select a format to save the file (using the Save as type drop down menu). The available formats not only include the old and new Microsoft Word formats (i.e. Doc and Docs) but also allow saving the file in PDF, HTML, HTM, Dotx, XPS and a range of other formats.
As is obvious, all you have to do is to select the format from this drop down menu and click Save. When you select the PDF format you will also be given the option to save the document in Standard format (for publishing online and printing) or in the Minimum size format (for publishing online).
Additional Document Settings
You can also specify additional settings for the document by clicking Options. This will open a new window from where you can configure additional PDF document settings such as enabling ISO 19005-1 compliance, enabling/disabling Bitmap text when fonts may not be embedded and Encrypt the document with a password.
