The document discusses the features of Adobe Reader and Acrobat Pro. Adobe Reader is free and allows users to view, search, print, and annotate PDFs with sticky notes, highlights, lines, and stamps. Acrobat Pro has all the features of Adobe Reader but also allows users to edit, convert, combine, and redact PDFs. It can recognize text using OCR, convert PDFs to Word and Excel, and combine multiple documents into a single PDF portfolio.
