A PDF is the best way to present your files, when you pdf your document it will help ensure that whoever receives your files will see the same as what you see. There can be issues with fonts and formatting with some pdfs so whenever possible you should always check your files on another machine. If your PDF writer gives you the option, then always choose Convert To Curves or Outlines. TIP1. try to use standard fonts ie Times New Roman, Arial etc this will lead to less problems.
TIP2. ensure you set your pdf page to the size you want to end up with ie A4, A5 etc.
REMEMBER
Word & Publisher usually default to US Letter not A4 and in Australia we deal with A4, A5 etc.
