Creating PDF files Portable Document Format (PDF) files allow documents generated by programs such as word processors and desktop publishers to be published electronically, preserving their original appearance, for viewing and printing on any system. On Mac, no additional software is required. To save a PDF of your score, choose File > Print, and click the Save as PDF button. On Windows, Sibelius supports the creation of PDF files provided you have a suitable PDF creator installed on your computer. The official PDF creator is Adobe Acrobat, which is a commercial product available from www.adobe.com for both Mac and Windows, but there are several free alternatives available, including PDFCreator, which you can download from: https://pdfcreator.sourceforge.net PDF files are generated by software that installs and behaves like a printer driver. This means that creating a PDF is as simple as printing a file from Sibelius, choosing the PDF "printer" as you do so. For further instructions, consult the documentation that accompanies your PDF creation software. To view PDF files, you need to have the free Adobe Reader installed on your computer (on Mac you can use the built-in Preview application instead). You can download the latest version of Adobe Reader from: https://www.acrobat.com
