About Portable Document Format Files

HTML, the code used to create Web pages, cannot maintain all of the original formatting and presentation of many documents. In such cases, AIRNow uses a different format called Portable Document Format (PDF). PDF documents maintain the look of the original document, and they can be viewed on any Macintosh, PC, or Unix computer. However, you must download and install the free Acrobat* Reader* program at http://www.adobe.com/products/acrobat/readstep2.html .Exit AIRNowPlease be sure to use the most current reader from Adobe to ensure compatibility for all PDF files on AIRNow's site.

Adobe provides online conversion toolsExit AIRNowfor Adobe PDF documents that help visually disabled users whose screen reader software is not compatible with the Adobe Acrobat Reader 5.0. These online tools convert PDF documents into either HTML or ASCII text, which can then be read by a number of common screen reader programs.
