Convert your documents e.g Words, Excel, Powerpoints into pdf format free online: http://www.zamzar.com/ https://www.pdfonline.com/convert_pdf.asp Just upload your file and the converted pdf will be sent to your email. By converting it to pdf format the file will be compressed (small in size and easy to be sent over email or uploaded to the web) and it is not so easy for someone to edit the file (e.g. the booklists which I had uploaded). This is very useful as for some competitions, the organiser actually request the files to be in pdf format.
