How to Change PDF Versionby Eric Brown
Since its creation, Adobe's Portable Document Format--or PDF--has undergone a lot of changes. Each version of Adobe Acrobat--the program used to create and edit PDF files--continues to add various types of functionality. Depending on your version of Acrobat or Acrobat Reader, you may not benefit from the functionality of certain PDF files. You can change the version of the PDF to extend compatibility to older versions of Acrobat to solve this issue.
Open the PDF you want to do a version change on. You can double-click the file to open it in Adobe Acrobat.
Click "Advanced" and select "PDF Optimizer" from the drop-down menu.
Click the drop-down menu labeled "Make Compatible with" and select the compatibility version you require. You can select from Acrobat 4 and up to Acrobat 9 and up. Click "OK" at the bottom of the window.
