Document Layout

To do this, you need a picture of your letter sheet in the JPG format. Simply save an empty Word document with your template for business letters in a PDF file (File -> Export -> PDF). You can then use the free web service PDF2JPG (https://pdf2jpg.net) to convert this PDF document into a JPG picture.
