Viewing Non-HTML documents on the Assembly website

We may use the following non-html file formats, on our pages. If you dont have the software installed to use these formats you can use the following information to help you do so.

PDF (or Portable Document Format)

File extension:


Opening PDF files

Most web browsers have built-in PDF readers and when you access a link to a PDF, the PDF will open automatically in the web browser.

Standalone PDF programs or apps are also available to download. These may offer more advanced features compared with browser-based PDF readers. Adobe Acrobat Reader is one of the most popular PDF readers and is available free of charge from the Adobe Acrobat site or from the app store on your device. 

Adobe Acrobat Reader is by far the most popular free PDF viewer but there are others available for download, for example Foxit Reader, that will allow you to view and print PDF documents on a variety of platforms and devices.
