All ISS computers are equipped with Cute PDF Writer software, which includes a PDF printer spooler. You can "print" any document to this printer, which will then create a PDF file. Moreover new Office 2010 software is able to save any Word, Excel or Powerpoint file as PDF. Just click on Save As... and select PDF as file format.

For Windows users:

You need to install a PDF converter on your computer. There are different PDF converters available. A commercially available program is Adobe Acrobat Professional. That is a licensed program that you need to purchase. ISS students and staff can purchase discounted software at www.surfspot.nl. There are also free converters available for download. In most cases they offer less functionality or are putting commercial messages on the screen and sometimes even in your PDF documents. We have tested and advise the following software: Cute PDF Writer. It is a free of charge software with proper functionality and without commercial stamps created in PDF files.

Just Google "merge pdf online" and you will get many hits for online solutions where you can upload multiple PDF and get one merged PDF in return. One of these websites is http://www.mergepdf.net. But, many of these websites have a hidden or even obvious commercial goal and are not always to be trusted.
