Although iOS supports PDFs natively (just like Mac OS X) there are features in the PDF spec that aren't supported in iOS or may never be. One of the things that has made the Portable Document Format (PDF) a success is that with the Adobe Reader of Mac, Windows and other platforms you get to have a consistent experience no matter where you view them. Now that Adobe has officially released the Free Reader for iOS and Android, "rich" PDFs can now be shared across both desktop and mobile platforms with a consistent viewing experience once again!

Here's what the Adobe Reader lets you do:

View PDF files:

• Quickly open PDF files from e-mail, the Web or any application that supports “Open In…”

• View ePortfolio (PDF Portfolios), PDF Packages, annotations and drawing markups

• Read text annotations such as Sticky Notes

Access encrypted PDF files:

• Open and view password-protected PDF files

• Access files secured by Adobe LiveCycle Rights Management, which helps protect sensitive documents

• Supports the highest grade of PDF encryption, up to AES256

Interact with PDF files:

• Search text to find specific information

• Use bookmarks to jump directly to a section in your PDF file

• Select single page or continuous scroll modes

• Easily zoom in on text or images for a closer view

• Quickly navigate through large files using thumbnails

• Select and copy text from a PDF file to the clipboard

Print and Share files:

• Print wirelessly with AirPrint

• Share PDF files with other applications using “Open In…”

• Email PDF documents as attachments
