Whenever i am not on my PC, most of the time i get windows to work upon, (if Linux is not there). In such a scene if i have a need to convert .doc or .ppt like files into pdf , i just attach the file in one mail and send it across to the following id:
Shortly, i receive an e-mail containing the pdf version of the file i sent. So, isn’t my e-mail enough? Go for it!
