Conclusion: It doesn't do everything, but Adobe Acrobat is still the most powerful, stable, and mature PDF application, from the creator of the PDF format.
Pros: Vastly improved editing features for text and graphics; improved graphical interface for combining documents into a single PDF; enhanced export capacity; improved online web-creation and document-signing features.
Cons: Massive feature set can make navigation confusing; a minor annoyance requires multiple steps when performing OCR on some PDFs.
Summary: The eleventh release of Adobe’s venerable PDF productivity suite, Acrobat XI delivers a raft of new and enhanced features, ranging from all new text and image editing tools to greater integration with online cloud services, both from Adobe and others. Forms creation is also simplified in the updated product, as is the process of electronically signing documents using the online EchoSign service, acquired by Adobe in 2011.
