Office 2010 provided the option to save a document as PDF, and Office 2013 provides two more exciting features to PDF manipulation,

• Import and Edit PDF directly in Word 2013, so you can use Word 2003 as PDF Reader and PDF Editor
  When you open any PDF file in Word 2013,  it starts to convert it using Microsoft PDF Reflow.
  Microsoft PDF Reflow, will convert all the files contents, including its formatting like paragraphs, lists, headers, columns, footnotes , tables, etc, into Word content. You will be able to edit even the tables. I tried with various smaller PDF documents and it kept all its formatting, even after the conversion.

• Word 2013 and Excel 2013 can save password protected PDF

PS. if you want to remove the password of PDF document, please try the online version pdfdecrypt or pdfcrypt, and if you forgot the password, please try pdfcrack.

First, Convert every PDF page to image(for example jpeg), and view Jpeg on PSP,
PDF2PSP is a tool for converting PDF documents and print outs into JPEG images suitable for displaying on the Sony PSP handheld game console.
Second, directly View the really PDF on PSP, and you need Bookr,A document reader for the Sony PSP with native PDF rendering.
To use Bookr, you need a Sony PSP with firmware version 1.5, other firmware versions are not supported.
