Adobe Reader software is the global standard for electronic document sharing. It is the only PDF file viewer that can open and interact with all PDF documents. Use Adobe Reader to view, search, digitally sign, verify, print, and collaborate on Adobe PDF files.
Adobe Reader XI provides full commenting capabilities, including text, stamps, file attachments and audio recordings, as well as drawing markups, like lines, arrows, shapes and free-form annotations. Do you have a PDF form that needs attention? Well, Reader is now able to fill, sign, save and send your forms without requiring printing and mailing. And, of course, you can do this on the most recent and popular operating systems, OS X Mountain Lion and Windows 8, which includes our new “touch-mode” for an optimal tablet experience.
