Why use Adobe PDF (portable document format)?
Preserve the look and integrity of your original documents - Adobe PDF files look exactly like the original pages and can fulfill requirements for electronic filing and increased document security.
Share documents with anyone - Anyone using free Adobe Reader® software can open Adobe PDF documents across a wide variety of platforms and devices.
Easy to use - Adobe PDF files have a wide range of features to enhance usability, color profile information for more accurate color rendition across different systems, as well as tags in the document that reflow the pages for different screen displays.
More secure document exchange - With Adobe Acrobat® 8.0 software, you can password-protect PDF files to help prevent unauthorized viewing and altering.
Searchable - Adobe PDF files are searchable for words appearing in the text and in annotations, bookmarks, and data fields.
NOTE ADOBE FILES ARE LOCKED - so you can't change them.
