Adobe PDF

Adobe PDF is a file format which saves existing documents with all their original formatting. This means that, when you look at a PDF document, you will see the formatting and layout that the author intended, even if you do not have the program they originally created it in.

In order to view PDF documents, you will need to have the free Adobe Acrobat Reader software installed on your computer.

On the Adobe website, make sure that you choose the right options in the drop down boxes before you download. Make a note of where you are downloading the installation file to (e.g your desktop). After the download has completed, locate the installation file on your computer and double click on it. The installation programme will do the rest.

Once the Adobe Acrobat Reader software has been installed you will be able to read Adobe PDF files.

Saving a PDF

To save a PDF to your PC computer, right click your mouse over the PDF link and select 'save target as' or 'save link as'. If you have an Apple computer, click the link whilst holding down the 'option' key. You can then save the PDF where you want on your computer.

Accessible PDFs

We recommend that users download the latest version of Adobe Acrobat Reader to access Adobe PDF files. The latest version of Adobe Reader enables users to read and use Adobe PDF documents and forms more easily - and across multiple languages.

Adobe PDF troubleshooting

I have clicked on the link but my browser has just gone blank
Browsers have different ways of downloading PDFs. Most will ask you where you would like the file to download on your machine and show a progress meter as the file downloads. However, some browsers load in the PDF page by page and don't show a progress meter. In fact, the file is downloading - the first page should appear after a few minutes.

I've downloaded the file but nothing has appeared
You may need to go to where the file was downloaded on your local drive (probably your c:/windows/temp directory) and click on it from there. If it doesn't work, your Reader is not working properly and should be reinstalled.

For further troubleshooting suggestions, see Adobe technical support.
