Out of interest what software do you use for writing pdf documents. Been searching the web and there are loads. Some are very expensive too.
I have Adobe Acrobat Professional in work and use it all day long.
At home I use
convertword2pdf.com/.
Simple upload the file and then download the PDF version. It's free and you'll never be without it so long as you have internet access
The site above will convert many documents, see
here.
Good luck.
