Major help needed on PDF makers?

I have an existing PDF file that is a novel I wrote and need to submit to my publisher. Right now the size is 6X9inches, and they need it to be exactly 5.25X8 Inches.



I have both Nitro, and Adobe Acrobat 9.0 pro. I need to know EXACTLY how to change the PDF size to the one that I need.



Best answer to the person who knows exactly what to do. I have already gone to printer preferences, and added that size to the list of available sizes. I cannot for the life of me change the existing PDF I have though TO THAT SIZE.

Open your PDF in Photoshop %26gt; resize every page using the Image menu %26gt; Image Size. In Image Size dialog box using the drop down arrows change from pixels to inches in Width and Height boxes and enter the size you need. When all pages are resized, go to File %26gt; Automate %26gt; PDF Presentation. Click on Add Open Files and put in order the pages, then check Multi Page Document.

Once you click the Save button, Photoshop will ask you to save your PDF. Then the Save Adobe PDF dialog will appear, giving you the standard PDF output options: choose Press Quality. On the left click on Compression and choose High. Now you can click on Save PDF.



If you don't have Photoshop get a trial from Adobe:
