Adobe Acrobat is a platform for viewing, creating, manipulating and managing files in Adobe's PDF format.

The company will offer only one version of Adobe Acrobat 9 for Mac users, a Professional version, sources said. The company is discontinuing the Standard version on the Mac with the next release. However, Windows users will still have the option of choosing the Standard or Professional version of the product.

Moreover, users acquire Acrobat to create forms that can be completed electronically by users. That capability was previously available only in Acrobat Professional. But with Acrobat 9, this capability also will be in the Standard version, sources said
