Our Adobe Acrobat integration makes working with PDF documents simple. Open any PDF stored in your Dropbox account with the built-in Adobe Acrobat PDF annotator, and you can annotate, highlight text or markup PDF files from any device. When you edit a PDF, changes are automatically saved to your Dropbox, and you can easily share the updated version with your co-workers. PDF annotations
