It depends what you want to do. SOME functions work in Acrobat Standard. A very few functions even work in Acrobat Reader, but think of the SDK as a marketing tool so everyone needs Acrobat.
Thank You. So our need is converting multiple PDF files to XML files using Acrobat SDK. For that do we need Acrobat Pro DC tool?
Acrobat Standard might work. Unfortunately, there is no table of supported features. Which API do you propose to use for this? If not sure about API, which user interface feature? Acrobat exports multiple kinds of XML, entirely different.
