Known as the Portable Document Format or PDF for short, these files are primarily created by Adobe Acrobat although many word-processing applications and desktop-publishing tools support the creation of .PDF files through plug-ins.

These files are extremely popular when distributing digital copies of a document, as the format allows the document to be presented exactly how it looked when created - retaining original fonts, formatting etc regardless of the operating system or platform used to view it.

PDF files can be viewed using Adobe's free Acrobat Reader application, or one of the numerous free alternative viewers.
